CHEMICALS

BEFORE BUYING OR USING CHEMICALS, PLEASE READ THE FOLLOWING INFORMATION CAREFULLY

UNDERSTANDING THE CLP LABELS The CLP Regulation is the new EC Regulation No 1272/2008 on Classification, Labelling and Packaging of substances and mixtures. The legislation has been introduced throughout the EU as a new system to classify and label chemicals based on the United Nations Globally Harmonized System or GHS. Why is it changing?

The new system is to allow uniformity within the United Nations so that all countries worldwide have the same classification for transporting and supplying chemicals. The GHS provides a single system to identify the hazards that will be the same in every country.

When is it changing?

The CLP Regulation came into force on 20th January 2009, however a transitional period was put into place so that industry and users could adapt. Newly purchased substances must be classified, labelled and packaged according to CLP on 1st December 2010, however, those chemicals already on the shelves can continue to be supplied under old legislation until 1st December 2012. The corresponding dates for mixtures are 1st June 2015 and 1st June 2017 respectively.

What are the changes?

Users will start to see new pictograms, hazard and precautionary statements, and signal words on chemical labels as suppliers switch to the GHS system. Many of the new GHS pictograms are similar to the existing EU system, but they have been re-designed with new shape and colour. They are not an exact translation of the old symbols and instead of a specific hazard word e.g. toxic, flammable; they are numbered and assigned to a range of categories of substances, an example of this is shown on the following page in the example table.

What are the Signal words?

The CLP Regulation has introduced two new signal words: ‘Danger’ and ‘Warning’. If the chemical has a more severe hazard, the label includes the signal word ‘Danger,’ in the case of less severe hazards, the signal word is ‘Warning’. In some instances chemicals may have a signal word but no pictogram. As was the case under the old system there are also a number of substances which carry no hazard warning pictograms or signal words.

What do these changes mean?

As the criteria for classifying chemicals have changed, some chemicals you have previously used may have changed classification, and some that were not previously classified as hazardous may now be labelled as hazardous. • If you use chemicals, you should: • Look out for the changes and check that you are doing what is needed to use the chemical safely. If you are an employer, alert your employees to these changes too. • Speak to your chemical supplier or CLEAPSS if you have any questions or if you don’t understand the changes that have been made. • If you are an employer, provide your employees with adequate information, instruction and training. • Follow the advice provided on the new labels and, where appropriate, in Safety Data Sheets.

Please note: The regulations governing the transportation of chemicals have also been subject to recent changes. The list of chemicals with special carriage requirements has expanded as a result of the ADR 2011 regulations (Carriage of dangerous goods European Agreement concerning the International Carriage of Dangerous Goods by Road). Those chemicals which carry ADR restrictions are indicated within the ‘Chemicals’ section which follows, by a statement and, as in previous years, are subject to an additional carriage cost. Contact Customer Service Department for further information and charges.

CARRIAGE SURCHARGE:

Certain chemicals e.g. lithium, potassium, methanol, bromine etc, may now only be transported by ADR vocationally trained drivers. This has forced us to implement a carriage surcharge (subject to application) per order which contains these chemicals (which are clearly marked in the chemical section). Please note: The regulations governing the transportation of chemicals have also been subject to recent changes. The list of chemicals with special carriage requirements has expanded as a result of the ADR 2011 regulations (Carriage of dangerous goods European Agreement concerning the International Carriage of Dangerous Goods by Road). Those chemicals which carry ADR restrictions are indicated within the ‘Chemicals’ section, which follows, by a statement and, as in previous years, are subject to an additional carriage cost.

Certain chemicals are of a hazardous nature and require special delivery and handling, which can be expensive or cause delays with the delivery. For this reason we separate chemical requirements from all enquiries and provide a separate quotation for hazardous chemicals. Contact our Export Customer Service Team on: 01 447 5277 or email: export@timstar.co.uk with all your enquiries.

HOW DO I WORK OUT THE MOLARITY OF A CONCENTRATED ACID FROM THE PERCENTAGE ASSAY? To work out the molarity from a percentage solution you need to know: •

Percentage concentration of the solution (assay)

•

Molecular weight (Relative Molecular Mass)

•

Density of the solution in g/litre.

€16,33

Molarity = density (g/l) x assay(%) ÷ mol. wt. 100 Example: Orthophosphoric acid • • •

Assay (concentration) = 85% Molecular wt = 98.00 Density = 1.7g/ml, = 1700g/litre 85 ÷ 98 = 14.75M solution. Molarity = 1700 x 100

For Orthophosphoric acid, 14.75M = 44.24N – as the Molarity and Normality depends on the number of Hydrogen atoms in the formula i.e. H3PO4 has 3 x H so 1M = 3N.

You can find the SD sheets by using this link: timstar.co/chemical-sd-sheets

Other examples: HCl has 1 x H so 1M = 1N; H2SO4 has 2 x H so 1M = 2N.

WHAT ARE THE BENEFITS OF USING TST STERILISATION STRIPS OR TAPE IN AUTOCLAVES? TST strips (Temperature, Steam and Time) and Autoclave Indicator Tape are useful, if not essential, when using autoclaves, as they give a clear indication that the sterilisation cycle has been completed correctly. This is particularly important when disposing of spent cultures, to ensure that all microbes have been properly destroyed. The TST strips will change colour when the correct conditions have been reached (i.e. temperature, steam & time) and Autoclave Indicator Tape will change colour to indicate that the contents have been autoclaved. (Please note that this is not as specific as the TST strips as it ONLY indicates that autoclaving has taken place, rather than that specific conditions have been attained). Timstar offers 3 types of TST strips - 121˚C for 15 minutes (AU00980); 126˚C for 11 minutes (AU100200) – as well as an autoclave indicator tape (AU00976). We strongly recommend the use of sterilisation indicators, to be sure that the correct sterilisation conditions have been achieved. Please note: Autoclaves should never be overfilled, as they will struggle to get to the correct temperature and pressure levels and sterilisation times will need to be longer. This should not be as much of an issue with the automated types of autoclave, but could still be a problem.

BALANCE CALIBRATION MASSES The table (right) will help you to select the correct class of calibration mass for your balance. All of our calibration masses are OIML approved and UKAS certificates or in house statements are available for an extra fee. OIML stands for the Organisation Internationale de Métrologie Légale (International Organisation of Legal Metrology). OIML standards fall into a number of different classes, the main classes being, in order of accuracy, E1, E2, F1, F2, M1, M2 and M3, with E1 calibration masses being the most accurate and M3 the least accurate – this being reflected in the prices. We offer ranges and sets of F1 masses and M1 masses, which provide the accuracy required for calibrating the majority of balances used in schools. E2 weights are also available on request.

Clifton Centrifuges

Max speed Acceleration / Deceleration time

NE 010 G Centrifuge, Mark II The newly reengineered Targa Centrifuge from Clifton spins at up to 4000 rpm, with an acceleration/deceleration time of less than 20 s. An audiovisual alarm sounds when deceleration is complete, and the lid is released automatically. The built-in timer allows operation for up to 100 minutes, or continuous use. It is supplied with a 6-place angle rotor, which includes 6 aluminium sleeves for 15 mL tubes. The rotor is removable for easy cleaning, and the push-button control is wipeclean. The rotor can only be energised when the lid is correctly closed and locked. A viewing window in the lid enables the rotor motion to be observed. To prevent debris leaving the rotor area, a rubber seal provides a barrier when the lid is locked in position. Fitted with rubber non-slip fit, it is built to the latest safety standards, and supplied with comprehensive operating instructions. • Imbalance cut-out • Lid drop protection • Lid lock • Auto door release

Designed specifically for use in education, the Clifton Targa Centrifuge has been reengineered, and features the key features of all the previous Clifton models. It is compact and robust, making it ideal for routine lowspeed configuration: perfect for fractionation of samples, and simple separation of biological cells.

Ohaus Frontier 5306 Mini Centrifuge

Although competitively priced to suit education budgets this centrifuge has been designed to be used in Medical and University research laboratories. Some of the main uses include separation of serum, plasma, urea and blood samples. With a speed range of 3004500rpm and a maximum rotor capability of 8 x 15ml tubes the clinical centrifuge allows precise control of time and speed ensuring an efficient separation process. The centrifuge also has 15ml cell culture tubes and a full line of collection tubes which is ideal for a clinical laboratory. The stable design and noise level of less than 56dB allows the centrifuge to work without becoming a disturbance in your laboratory. The centrifuge’s CPU controls all operating parameters including speed and time settings. Operation of the centrifuge can be timed from 30 seconds to 99 minutes or can be run in continuous mode. Timing will only commence when the set speed is reached ensuring that the separation time is highly accurate. The centrifuge breaks gently to preserve separation and not damage samples. The large, user friendly LCD screen displays all information including RPM and G Force. Parameters of the centrifuge can be set and modified after the set speed is reached. A quick spin mode is also available which is activated by pressing and holding the ‘PULSE’ button. The centrifuge can be accelerated to the required speed and held for as long as the button is held down and also has an automatic lid release. When the process is finished this saves time and protects samples from heat build-up. • Max. Speed [rpm]: 300-4500, increment: 100 • Max. RCF [xg]: 2490xg, increment: 100xg • Speed Accuracy [rpm]: ±20 • Rotor Capacity: 12x10ml/7ml/5ml; 8x15ml • Run Time: 30sec-99min-HOLD (Continuous operation • Driving Motor: Brushless DC motor • Safety Devices: Autolock lid when centrifuge is spinning • Quiet operation <56dB • User friendly Large LCD screen • Education price for Medical/ University specification • Quick spin Mode • CE marked • Spins to 4500rpm • Detailed Instruction Manual included

The OHAUS Frontier 5306 is a small but powerful mini centrifuge for simple and quick liquid separation. With an 8-place 1.5 mL or 2 mL tube rotor as well as a 4 place PCR 8-strip tube rotor, the Frontier™ 5306 can accommodate 0.2 mL 8 strip tubes or 32 individual PCR tubes. With the included adapter, 0.2 mL and 0.5 mL tubes can also be accommodated in the 8 place tube rotor. This centrifuge provides quiet, safe, and easy operation for your everyday quick spin-down applications. With a low voltage power input, quiet brushless motor and a rubber base that absorbs vibrations, the Frontier 5306 minimizes operational noise and reduces disruptions in the classroom. It is designed with operator safety in mind, and includes a rotor imbalance sensor and two safety switches which immediately stop the rotors should the lid open during use. It is also very easy to use - simply place your sample in the centrifuge, close the lid, and it will begin to rotate without the press of a button. • Speed: 0 – 6,000 rpm • Max. relative centrifuge force: 2,000 g • Max. capacity: 8 x 1.5 mL/2 mL tubes

Vortex Mixers Vortex Mixer The PV-1 vortex mixer from Grant-bio is compact, and has a low profile and small footprint, to sit in almost any location. Although small enough to fit in your hand, there is no compromise on performance. The reliable motor produces regulated and reproducible agitation throughout the speed range. It is also extremely quiet. With variable speed from 750 to 3000 rpm, the PV-1 can be used for gentle through to vigorous mixing and pellet re-suspension in 0.5ml, 1.5ml, and 15ml tubes. • Adjustable speed control: 750 to 3000 rpm • ‘Continuous’ or ‘touch’ operation • For tubes up to 20 mm diameter • Pressure sensitive cup accommodates tubes up to 20mm diameter • Reliable and extremely quiet motor produces regulated and reproducible agitation throughout the speed range • Extremely easy to operate - select either ‘continuous’ or ‘touch’ operation and turn the knob to adjust the speed from 750 rpm to 3000 rpm • In ‘touch’ mode, agitation starts in response to pressure on the pressure sensitive cup. • Exceptionally compact with a low profile and small footprint - fits into almost any location • Rubber suction pads hold tight to the work surface and prevent the unit from ‘walking’ - they also absorb vibration and prevent its transmission to the workbench

Signal Generator This has to be the best signal/function generator available for educational use! Developed in conjunction with physics teachers and designed specifically for education, this unit provides all the functionality you need for physics teaching. A really useful feature for those less familiar with using signal generators is that for basic use, you just operate two buttons: One for frequency and one for amplitude - that’s it! There is, of course, far more sophistication for those who require it. If you want to change waveform or to utilise the step and sweep modes, the display keeps you updated on the status of the generator. Unique frequency control: The frequency is set by a speed sensitive button. Turn slowly to set the display’s last digit, turn faster and the response accelerates - designed to work intuitively in practical experiments. Drives speakers, vibration generator etc. directly: The built-in 10 W power amplifier effortlessly drives power appliances e.g. vibration generator. The amplifier can deliver more than 1 amp for all frequencies between 0.001 Hz and 100 kHz. Step mode: In many applications you need to study a physical system at a fundamental frequency and at different multiples of that frequency. The special step feature makes this task incredibly easy. Once the fundamental frequency has been determined (e.g. of a spring connected to a vibration generator), other harmonics (or overtones) can be demonstrated by simply pressing a button, which changes the frequency to progressive multiples of the fundamental frequency. Sweep mode: The generator can sweep through a frequency range in order to discover eventual resonances. You decide the frequency range and the speed. You have the choice between a linear sweep (fixed number of Hz per unit time) and a logarithmic sweep (fixed number of octaves per unit time). Advanced Features: The generator connects to your PC through a standard USB cable and acts as a USB flash drive. Custom defined waveforms (e.g. created by means of a spreadsheet) can be saved to the generator. Sequences of settings can be programmed for automatic execution.

PURIFIED WATER FOR USE IN LABORATORIES Purified water for use in school science laboratories is essentially water which has had inorganic impurities removed to varying degrees, depending on the method, producing what is often called demineralised water. The most commonly used types of purified water in school laboratories and prep rooms are as follows:

Distilled Water

Deionised Water

• Water stills can be expensive to run (electrically) but produce

• Charged ions are removed in a deioniser containing ion-exchange resins, which consist of small resin beads composed of organic polymer chains with charged functional groups. These remove charged anions and cations from water as it passes over them.

• Salts and minerals are removed by boiling tap water in a water-still

and re-condensing the vapour (steam) produced, leaving dissolved minerals/salts behind. much larger quantities of purified water than deionisers before replacement parts may be needed (heating element for stills, resin cartridges for deionisers).

Reverse Osmosis (RO) Purified Water

minerals/salts from water using a semi-permeable • Life expectancy of deionising cartridges depends on water hardness, • Removes membrane under high water pressure purity of the tap water and volume of deionised water produced. In hard water areas deionising cartridges will not last long before the resin becomes exhausted, so this would not be a very cost-effective way to produce purified water.

108

• RO can also be used in conjunction with a deioniser to produce

very pure water. An added benefit of using RO as the first stage of the process is that deioniser cartridges (resins) last much longer, due to most of the impurities having been removed before reaching the deioniser - the resin therefore becomes exhausted less quickly

There is an overtemperature thermostat mounted in the boiling chamber as an additional fail-safe. The acrylic safety screen and the cabinet lid are removable giving easy access to the glassware components. Screw threads are incorporated on all water connections so hoses can be fitted and removed easily and safely without risk of breakage. The control is a simple and effective system which can be fitted to virtually any type of reservoir vessel. It will turn the still off when the reservoir is full, and restart it when the level in the reservoir drops, making it fully automatic. • 4 L/hour output • Highly efficient • Fully automatic • Built-in “clean” function • Wall mounting bracket included

Please note: These water stills should be direct wired to the mains power supply via a fused spur as they operate at about 13 Amps. It is not recommended that they are wired to a 3-pin plug.

RECYCLING BATTERIES Please consider recycling your old batteries when finished with or no longer required. Many batteries contain chemicals that are harmful to the environment when not dealt with correctly. The discarding of batteries in refuse bins means they will end up in landfill sites, causing pollution. Many shops and supermarkets, as well as council recycling points and waste disposal sites, have a battery collection point. All battery types sold by Timstar can be recycled (both rechargeable and non-rechargeable as well as button cells), as can battery packs from electronic and electrical equipment. It doesn’t matter if the batteries are full, completely discharged or part used. For further information go to:

CELL OR BATTERY? A cell (also called electrolytic cell or voltaic cell) is a device which has two electrodes in an electrolyte, producing electricity by electrochemical reaction. The output is a smooth direct current/voltage (dc). A battery consists of two or more electrolytic cells which are connected together to function as a single unit to give a higher dc voltage or current output (higher current when connected in parallel, higher voltage when connected in series).

NON-RECHARGEABLE BATTERIES

These are single-use only. Also known as primary cells or Leclanché cells, with a gel type electrolyte. Mostly used in devices which have a low current requirement although alkaline types can be used for both low current drain & high drain devices. Voltage is typically 1.5V from a single cell. Voltage falls steadily during use. TYPES Zinc-Carbon (ZnC) – These are usually the cheapest but have the shortest life during use. Zinc-Chloride (ZnCl) – Similar to ZnC but with a slightly longer life. Alkaline – These have the longest life and can also be used for high drain applications (e.g. cameras). Silver oxide button cells – These give a steady voltage discharge over a longer period before it drops off, with a longer operating life than the alkaline equivalents. Alkaline button cells – The voltage drops below the nominal quicker than with Silver oxide cells. They are cheaper but have a shorter life during use. Lithium coin cells – These have a high energy capacity to mass ratio and produce a higher voltage per cell – typically 3V.

RECHARGEABLE BATTERIES

Also known as secondary cells or accumulators. Voltage remains fairly constant during use until nearly exhausted, when it falls rapidly. Voltage is typically 1.2V from a single cell - due to the chemistry involved this is the limiting factor. TYPES Nickel Cadmium (NiCd) – These are an older type, now replaced by NiMH types. They tend to suffer from ‘memory effect’. Nickel Metal Hydride (NiMH) – The universally used type of rechargeable cells & batteries for general use. Memory effect is not really a problem. NOTE: Both NiCd and NiMH types self-discharge during storage due to the nature of their chemical and physical properties so it is always worth recharging again before use if stored or unused even for short periods. ‘ReCyko’ – This is a brand name of a newer type of NiMH rechargeable cells & batteries, which arrive fully charged and will not discharge as readily as normal NiMH types. They should retain up to 85% of their charge when stored for a year – far more than standard NiMH cells & batteries. Lithium-ion – These have a high energy capacity to mass ratio and no memory effect. Often used in laptops, digital cameras, camcorders and other portable devices. They do not readily self-discharge and give a higher voltage per cell – typically 3.6V. Lead-acid – These are ‘wet cells’ but more recently ‘gel cells’ where the electrolyte is either liquid or gel. Usually used for vehicle batteries and alarms and are able to deliver a high current, although they are usually larger and heavier than other types of battery, for the same voltage rating.

AMP HOURS

Rechargeable batteries usually have the capacity specified in milli-Amp hours (mAh) or Amp hours (Ah). This is the amount of current the battery should be able to supply in one hour. For example a battery rated at 2300mAh should be able to supply 2300mA for one hour. Of course if the current drain of the device being powered is lower or higher, the battery life (discharge time) will be longer or shorter.

Battery Tester, Professional This professional type battery tester, made by Ansmann, gives a true indication of the capacity of a whole range of commonly used battery types. Not only does it give a voltage reading but also indicates the remaining battery capacity as a percentage relative to full capacity (100%). Most simpler battery testers will only indicate the voltage of a battery without a load connected (i.e. not powering a circuit), which can often be misleading as once a load is connected the voltage can drop very quickly if the battery capacity is low - even though the voltage reading may have been fine. The Ansmann professional tester eliminates this possibility, giving a reliable indication of the actual capacity of the battery being tested. The tester can be used to test: Alkaline, Lithium photo, Lithium button, Zinc-Air, NiCd, NiMH battery types including all commonly used 1.5 V alkaline cells (AAA, AA, C, D), 9 V PP3, 1.5 V button cells, 3 V Lithium coin cells, 3 V Lithium photo batteries, 6 V Lithium photo batteries, 12 V alkaline (A23), 1.44 V Zinc-Air and 1.2 V NiCd and NiMH rechargeable batteries (AAA, AA, C, D). Simply place the battery onto the tester and check the reading, or connect the probe to one end of the battery cell then check the reading (depending on type being tested). The LCD indicates Voltage along with battery capacity in 10% steps and includes a self-test button to test the internal battery capacity. Includes 9 V PP3 battery, test probe, instructions and two year warranty.

Compact Battery Tester Test the condition of your batteries using this low-cost, versatile and compact battery tester. The tester uses the power of the battery you are testing to power itself, so does not require batteries. • Suitable for checking the state of Zinc chloride, Alkaline and Rechargeable batteries • Will test AAA, AA, C, D, 9V PP3 and N batteries €40,62 ea

Microslide System

Top quality specimens are photographed under optimum conditions, magnified, labelled and turned into strips of colour transparencies in sets of related pictures. The notes are clearly and precisely written with all the important words highlighted. The viewers are tough, child-proof magnifiers. They can also be used as simple low-power microscopes for examining soil samples, pollen, parts of flowers, small insects, etc.

Biosets Microslides Microslides are sets of 8 related 35mm images, as photographed through a microscope, and designed to be viewed through a Microslide Viewer (Bioviewer – MS88800). Arrows and callouts help the students locate important features being studied, accompanied by a detailed text folder designed to stimulate, inform and question the students about the topic. Each text folder has a handy pocket to store the Microslides. Supplied in packs of 10.

• Superb Quality photographs • Every student looks at the same image • No searching or focusing problems • No breakages • Students can work at their own rate

Bioviewers Microslide Viewer (Bioviewer) BioViewers are tough styrene instruments, almost unbreakable and made for years of wear in classroom conditions. They do not need any special treatment or care, they can even be washed. No lamp is needed; the white reflector stage provides sufficient light for a bright image. They can be used in any room at any time or even outdoors. With BioViewers you can stop worrying about expensive apparatus in inexperienced hands.

Protein Models

Amino Acid Starter Kit

Beta Globin Folding Kit

Explore the primary, secondary and tertiary structure of proteins with the captivating models and tools in this dynamic kit. Students learn the chemical properties of the 20 amino acid side-chains with dynamic, accurate, side-chain models featuring embedded magnets in a durable plastic. Side-chains feature dual colouring schemes - a coloured band at the base of each side-chain indicates chemical properties, while embedded coloured balls in the model show atomic structure. Understanding protein structure begins with this unique combination of structure and chemical properties of the amino acid side-chains. Through the kit’s engaging hands-on activities, students gain a basic knowledge of protein folding. Then they discover the importance of secondary structure with an additional folding activity. Each kit includes: 1 magnetic chemical properties circle, 1 amino acid side-chains list, 22 amino acids, 1 4-foot Mini-Toober (a flexible foam modelling rod with a soft wire core), 15 metal clips and 6 hydrogen bond connectors, a CD with teacher notes, student hand-outs and interactive Jmol visualisation (an open-source Java viewer for chemical structures in 3D). The 3 group kit contains 3x each of the above.

Proteins become real in your students’ hands with this as they fold 3 Mini-Toober ß-Globin fragments and discover the primary, secondary and tertiary structure in this model. Maps guide your students in folding the Mini-Toobers into ß-Globin’s 3-D shape. This Kit is the next step in helping your students understand proteins, after engaging in the Amino Acid Starter Kit© activities. The Mini-Toober ß-Globin Folding Kit© includes Mini-Toobers, folding map guides, amino acid sidechains, haeme group, iron atom, oxygen atoms, and an assortment of parts to mark and connect the fragments. The Folding Kit can be used successfully by 6 to 9 students working in 3 teams. Available as a kit for self-construction, or a ready-made, pre-folded model.

DNA Models continued

Twist! Untwist! Replicate! Transcribe! Now students can do it ALL with theDynamic DNA Kit! Whether making health care decisions for themselves and their families or preparing for careers in medicine, research or drug development, today’s students need to understand DNA. Research shows that while students know DNA contains genetic information, they have trouble understanding how that genetic information is revealed and used.

Dynamic DNA Kit

DNA Starter Kit Students will immediately become engaged with this interactive foam model of double-stranded DNA and single-stranded RNA. The DNA Starter Kit© is a schematic model that transforms from the familiar ladder shape to the double helix with a twist. Students can explore the structure of colour-coded DNA bases showing purines and pyrimidines which connect to a continuous sugar-phosphate backbone. Then they can delve into replication and transcription. Using individual nucleotide triphosphates, they can synthesize a new strand of DNA - one base at a time - showing the semi-conservative replication of DNA. Finally they can synthesize mRNA - one base at a time - to show the process of transcription. Each kit includes: 51 bases (12 red adenine, 12 yellow thymine, 12 blue cytosine, 12 green guanine, 3 white uracil), 4 continuous grey backbones, 24 grey sugar-phosphates, 12 lavender sugar-phosphates and 48 orange phosphates.

The kits contain the following: 2 Base Pairs 6 A-T and 6 G-C base pairs; 5’ hydrogen and 3’ oxygen parts; oxygen atoms to model RNA; removable carbons for uracil; ATP, TTP, GTP and CTP models; display stand; teacher resources and lessons 6 Base Pairs 3 A-T and 3 G-C base pairs, 5’ hydrogen and 3’ oxygen parts, oxygen atoms to model RNA; removable carbons for uracil; ATP, TTP, GTP and CTP models; teacher resources and lessons 12 Base Pairs Includes 6 Dynamic DNA 12 base pair sets; 5’ hydrogen and 3’ oxygen parts; oxygen atoms to model RNA; removable carbons for uracil; ATP, TTP, GTP and CTP models; 6 display stands; teacher resources and lessons

Detailed and accurate dissectable 6 part human eye model with detachable base and photocopiable key. Approximately 3 x life size. Dimensions (W x D x H): 90 x 90 x 150mm.

This innovative functional eye model is an open design model, offering high visibility, which does not involve the injection of liquid*! It is composed of a flexible lens with an adjustable focal length, which constitutes the crystalline lens for comprehensive visualisation. The adjustment of the crystalline lens is made by mechanical stress on the flexible lens, which is similar to the action of the ciliary muscles. The screen represents the retina that can slide along the optical axis to simulate vision problems (myopia, hyperopia). The lens holder is placed in front of the eye to allow a corrective lens to be put in place. The crystalline lens is equipped with an adjustable focal, without the need for further injection of a liquid*, which enables the study of vision problems and their correction. Contents: eye model and a kit of corrective lenses. *a one-time injection of liquid is required when setting up the apparatus for the first time only.

Biotechnology, Electrophoresis & PCR Introduction to Biotechnology Genetics & DNA Kit See genetic material with your own eyes as you isolate the DNA from a tomato in a test tube. Investigate inheritance and learn how traits are passed down from parents to children. Learn about dominant and recessive genes and play inheritance games to determine how traits will be expressed. Learn about the biology of reproduction, the components of cells, and how chromosomes are combined and copied. Assemble a model to see the elegant double-stranded helical structure of DNA. Then crack the genetic code and find out how the different parts, called nucleotides, fit together. Analyze DNA evidence to identify suspects and solve a crime. Breed your own bacteria colony to experiment with survival of the fittest. Read about how mutation affects genes and how scientists clone plants and animals. Head into the lab for an in-depth investigation of genetics, the branch of biology focused on heredity and variation in organisms, and DNA, the acid that holds the blueprints for life. Complete with 48-page colour manual.

D IN SEARCH OF THE KISSING DISEASE

Simulated ELISA Kit This kit has been designed for pupils in secondary education to give an extremely realistic simulation of ELISA, while being low cost and requiring very little preparation. There are multiple ways to use the kit, but the recommended practical experiment is the simulation of the outbreak of disease and identification of the source. The practical can be done in an hour, or comfortably in two 40 minute lessons. The kit contains: • 10 strips of 8 plastic wells • 20x small, empty plastic pipettes • 20x 1.5 mL centrifuge tubes containing ‘serum’ samples • 2x 1.5 mL centrifuge tubes containing positive ‘serum’ samples • 1x bottle containing 30 mL of ‘wash buffer + detergent’ • 10x sealed pipettes containing enzyme substrate • 10x sealed pipettes containing positive control • 10x sealed pipettes containing negative control • 10x sealed pipettes containing ‘primary antibody’ • 10x sealed pipettes containing ‘secondary antibody’ Stored in the fridge, the kit will last UP TO 4 weeks. Stored in the freezer above -20 °C, it should last up to 6 months.

Enzymes Basic Enzymology Kit

Enzyme Kits Enzymes are biological catalysts, they increase the rate of a reaction without being used up, they are found naturally in the environment and work at optimum temperatures and pH, at this point their activity is at the greatest. The kits below can be used to investigate various effectsof temperature/pH on reactions to determine optimumtemperature/pH and help illustrate how enzymes work.

Introduction To Enzymes Kit Demonstrates the effects of pH and temperature and the specificity of enzymes. Emphasis is placed on good experimental technique and appropriate deductions from the results obtained. Includes guide notes.

It is good practice to use tape to secure the lid of a petri dish during incubation to prevent contamination. However, it is important not to make an air-tight seal around the edge, as this will encourage growth of anaerobic bacteria. Instead, two small strips of tape on opposite sides should attach the lid to the base. Correct Way: Tape on top with label, two small strips attaching lid to base.

Petri Dishes, Glass Resistance glass.

Wrong way: Tape around circumference of where petri dish lid joins base risks making an air-tight seal, encouraging growth of anaerobic bacteria.

Choice Chambers Timstar Choice Chamber

CA1856

At last, the once ubiquitous Choice Chamber is readily available again, at an affordable price! Robustly made from injection moulded Acrylic, this is a modification of the ‘classic’ design. With four compartments for holding desiccating and humidifying components (e.g. silica gel or anhydrous calcium chloride and water or cotton wool soaked in water) a piece of fine mesh is placed over the compartments and the lid placed on top to hold the mesh in place. This mesh layer ensures the organisms cannot come into contact with the desiccant etc. below. The clear lid of the chamber has slightly raised ridges which divide it into quarters, to facilitate the placement of tracing paper or card segments, creating different levels of opacity or for light to be blocked out completely. This allows a range of condition gradients within the chamber to be created. The edges of the lid can also be blacked out if required, to augment the dark conditions. The organisms being tested (e.g. woodlice or maggots) are then introduced via the single 18 mm diameter hole in the lid. The lid fits onto the base in such a way that the top segment guides align with the compartment walls below, which means the different light level sectors of the lid will match the compartments in the base precisely. Available in a range of base colours with clear lids, the choice chambers come without the mesh material, which is available separately. Dimensions (Diameter x D): 200 x 35 mm.

Spirometer, ‘Clifton’ For investigating tidal volumes, respiratory rate, pulmonary ventilation, reserve volumes and vital capacity. Oxygen consumption can also be measured which is useful in metabolic rate studies. A simple lever control enables the subject to be connected either to the atmosphere or to the float for recording. A container for soda lime crystals is fitted which absorbs the CO2. The spirometer is designed to offer minimal resistance to airflow. This provides the user with greater comfort and ensures accurate results. The float is constructed from lightweight plastic and is calibrated in 0.5 litre steps with a maximum capacity of 7 litres. A pen arm allows attachment of a fibre tipped pen for recording results or for attachment to a position sensor for datalogging. The pen arm was originally designed to be used with a Kymograph. However, these are no longer available so we suggest using with LogIT datalogging sensor DA61263 (Movement & Position sensor). Two flexible corrugated breathing hoses 0.8m long are provided. Supplied with two mouth pieces and a noseclip. Complete with full instructions.

The food calorimeter offers a superior method of measuring the energy in foodstuff, compared to burning it under a boiling tube of water. The enclosed vessel and copper tube ensure that more of the food’s energy is used to heat up the water, and less heat is lost to the environment, increasing the accuracy of the experiment. The unit comprises a glass jacket with a bell jar inside. A spiral copper tube draws air through the bell jar, in which food is burning, transferring more of the heat to the water. The lid has holes for a thermometer and stirrer. The base unit has clips to hold the calorimeter unit securely, a crucible holder, and posts for a replaceable ignition coil. The bottom of the base has 4 mm sockets for connecting a power supply to the ignition coil. A sample of food is placed in the crucible, the calorimeter unit placed over the top, and filled with water. The power to the ignition coil is turned on, and the food ignited. The temperature of the water is recorded, and the energy released can be calculated from the temperature change. To increase accuracy further, the calorimeter can be calibrated using a spirit with known energy density. Also required: a 12 V power supply, 4 mm plug leads, a 0.1 g resolution balance and a crucible. Please note that the calorimeter unit and base are sold separately, and both are required.

Disclosing Tablets Disclosing Tablets help to identify plaque (a mixture of acid producing bacteria and sugars) on teeth by dyeing the plaque a bright colour. This indicates the areas that need to be cleaned more thoroughly. The tablets are chewed then spread around the teeth using the tongue.

Our range of taste strips offers tests for genetically linked taste test ability. Consisting of paper strips impregnated with a harmless quantity of a test substance (or untreated in the case of the control strips), subjects will be able to detect (or not) varying tastes or degrees of intensity of taste. The ability to taste these substances is known to be genetically linked (inherited) and depends on the presence of dominant or recessive genes. Having the ability to taste one substance does not necessarily imply that a different substance will also be detected. PTC (phenylthiocarbamide) test strips have a bitter taste for some individuals, the intensity of which can vary. Thiourea test strips also have a bitter taste sensation for some people. Sodium benzoate test strips have a taste which varies from person to person and can be perceived as sweet, salty, sour or bitter (or, in some cases, no taste at all). Control test strips are untreated paper strips, used to provide a negative response for comparison to the taste test strips.

The majority of our burettes are constructed of borosilicate glass, with ‘class A’ burettes offering the best accuracy (for analytical work) along with traceability (each has its own unique serial number). There are many different styles of burette available but ultimately the choice is down to personal preference, practicality, accuracy or price. The following is a brief summary of some of the differences.

Pinch clip burettes are an older and simpler design mainly used in education. Glass key stopcocks are the traditional type and are preferred by some teachers and technicians because of the smooth action, greater control and longer life than PTFE key stopcocks. These usually require light lubrication, using Silicone grease. PTFE key stopcocks are now the most frequently used because they do not need any lubrication, are less likely to jam than glass stopcocks, and are regarded as a lower maintenance option. Modular PTFE key stopcocks are made entirely of PTFE and are particularly suitable for schools as they are less delicate than the other types and all of the parts are replaceable separately. ‘Rotaflo’ type burettes have a screw in/out PTFE key which allows for fine drop control.

Pipette Rinsing System

E C

Pipette & Burette Rinsing System This useful washing/rinsing system allows pipettes and burettes to be automatically rinsed when connected to a tap and drain outlet. Particularly useful where unpleasant or hazardous liquids have been used, the apparatus holds pipettes and burettes up to 600mm in length. For convenience and flexibility, the washing/rinsing system is available as separate components. 1. The polyethylene rinser/washer fills via the spray nozzle on the top rim. Contaminated water will syphon out totally, once the syphon point at the top of the rinser has been reached via the large diameter drain situated at the lowest point, before refilling automatically. 2. During washing the pipettes/burettes are housed in a specially designed basket, which minimise breakages as it buffers the glassware tips against the soft polyethylene base. 3. A soaking jar is available, which will hold a pipette/burette basket, to allow the glassware to soak before rinsing. Low water flow rate is NOT a problem, but it is better to adjust the flow for a cycle of about 90 seconds.

Each cell consists of a 75 x 25 mm glass cylinder with a 2 hole rubber stopper fitted with 2 carbon electrodes. Electrical contact is made through the crocodile clips and a piece of insulating material between the electrodes prevents short circuiting. The gases evolved are collected in two 75 x 10 mm test tubes suspended over the electrodes by a piece of wood and rubber bands (not supplied).

This amazing clock is powered not by batteries but by damp earth! Simply fill the pots with earth, push in the metal rods and the clock will start. It is also possible to insert your own graphic designs into the clock face. Comes complete with metal electrodes.

CHEMISTRY

Electrolysis

Voltameters A voltameter is an instrument for measuring the quantity of electricity (i.e. the amount of electric charge). This is done by measuring the amount of element deposited or released at the cathode. In schools, they are typically used to demonstrate the composition of water being two parts hydrogen to one part oxygen.

Student Gas Voltameter

Hofmann Voltameter

For student experiments. Embedded platinum electrodes are connected via 4mm sockets. Two miniature test tubes are included for gas collection.

Comprises three parallel tubes, joined at the bottom with a horizontal tube. The central tube has a funnel for filling with water, and the side tubes have open ends at the bottom to allow bungs that hold electrodes to be fitted, and jets with stopcocks at the top for collecting gas in test tubes. The side tubes are graduated 0-50 x0.2 mL so that the volume of gas in each can be measured. Clamps and support base (sold separately) are recommended so the unit can be mounted on a retort rod.

FLAME TESTING Flame testing is best done using platinum wire, although this is very expensive. A cheaper alternative is to use nichrome wire, which works well but tends to give a trace of orange colour in a flame.

Metal compound (salt)

Flame colour

Barium

Pale green / green

Boron

Green / bright green

It is more effective to use a flame test wire with a loop at the end, as this allows more of the sample being tested to adhere to the wire.

Caesium

Blue / violet

Calcium

Orange-red / brick red

Copper

Blue-green / green or blue (depending on which ion)

Indium

Blue

Iron

Yellow-gold

Lead

Grey-white

Lithium

Red / crimson

Manganese

Light green / yellow green

Then the end of the wire or loop should be moistened again in the acid, dipped into the sample being tested (so that some sticks) and placed back into the Bunsen flame.

Potassium

Lilac / pink / violet

Rubidium

Red / red-violet

Sodium

Orange / orange-yellow

The table lists typical flame test colours for various metal compounds (salts). Please be aware that this is only a guide and colours may vary from sample to sample, depending on the source and purity.

Strontium

Red

Thallium

Green

Zinc

Blue-green

Wires should be cleaned first by dipping the end or loop into concentrated hydrochloric acid (HCl) and then placing in a hot (blue) Bunsen burner flame. This process should be repeated until no colour comes off the wire in the flame. Concentrated acid works best but diluted HCl can be used instead, although less effectively, if safety issues are a concern – the flame colours may not be so intense.

Please note: For all bottled gases, the volume of gas stated for each cylinder is the volume the gas will occupy at atmospheric pressure. For example, a 34 litre cylinder has an actual (water) volume of approximately 1Â€litre, due to the gas being so compressed and a 110Â€litre cylinder has an actual cylinder volume of approximately 1.6 litres. If using the bottled gases to fill rubber or latex balloons, due to the surprisingly large volume of a balloon (e.g. a 9”/23cm spherical balloon would have a volume of approx. 6.3 litres) and also to the pressure the balloon walls exert on the gas, the number of balloons which can be filled will be considerably fewer than expected – probably only 3 or 4 from a 34 litre cylinder (depending on the size of balloon) and perhaps only 1 from a 14 litre bottle.

Fragrance Compounds

Gel Wax

Suitable for aromatherapy devices, etc, these are genuine essential oils mixed with a volatile medium. Using a simple delivery system - e.g. a small fan blowing air over a moistened pad - a minute quantity can fragrance a room. The fragrances can also be used in other design and make contexts where a background aroma is called for. Supplied in 10ml glass bottles with a built-in dropper. One bottle will provide enough fragrance for 10 students. Please note: These fragrances are not suitable for use as body scents.

This unusual gel may be combined with fragrance compounds to produce DIY air fresheners. The gel melts at just 70°C so can easily and safely be poured into a mould. Colour it when molten by adding wax dye and fragrance it with aromatherapy oils. The correct mixture requires experimentation. If too much oil is added the gel will not set. If not enough oil is added there will be too little scent to permeate the atmosphere.

Shapes of Molecules Set The Molyorbital™ 8 model collection set contains sufficient parts to make the eight atomic models shown in the picture. The different shapes are examples of the orientations of the bonds and cover coordination numbers 1 to 6. Lone pairs are represented by brown spheres or brown pear shaped parts. The 2 extra pear shaped parts are included in the set to enable protonated models to be made. e.g. Acid/Base theory, the formation of H3O+ as a result of the migration of H+ from hydrogen chloride. Models: linear, HCl (hydrogen chloride); linear, BeCl (beryllium chloride); Bent, H2O (water); trigonal planar, BH3 (boron trihydride); Pyramidal, NH3 (ammonia); tetrahedral, CH4 (methane); trigonal bipyramidal, PCl5 (phosphorus pentachloride); Octahedral, SF6 (sulphur hexafluoride).

Mole Set This Mole Set contains samples of four different metals and helps students to visualise a mole of a substance in a solid state, as well as developing a better understanding of the concept of the mole, mass, molar mass, along with the differing properties of the various metals. The set contains four element specimens: copper, iron, zinc and aluminium, each containing approximately one mole (6.023 X 1023 atoms) of the element. Comparison of each sample, side-by-side, clearly shows that the same molar amount of different elements have different masses and occupy different volumes, due to each element having a different atomic mass and density.

Atoms Molymod Vibrating Atoms Model This vibrating atom model demonstrates how atoms making up a solid (e.g. a crystal) are held together by spring-like forces. If the model is held at arm’s length (easier on a firm board) and shaken lightly, the individual ‘atoms’ will vibrate and move independently due to the springs holding them together, but they remain in the same formation within the model, as they do in a solid. Best used for demonstration purposes due to the ease with which the springs can be bent or misplaced. Comprises 9 white ball atoms arranged in a 3 x 3 x 3 lattice, connected by 54 springs.

Periodic Table

Elements Poster, Extra Large

Elements Poster, 3D Lenticular

This beautiful double-sided periodic table poster uses images from Theodore Gray’s library of thousands of element samples; many collected or re-photographed especially for these posters. (A few highly unstable elements show a picture of the person or place after which the element is named, or a mineral that contains trace amounts of the element.) The posters are laminated on both sides and printed on the highest quality paper, using special processes which result in razorsharp images. Poster dimensions: 68 x 134cm (27” x 53”).

This amazing 3D version of Theodore Gray’s original Periodic Table of the Elements poster is printed using lenticular technology, which uses linear lens elements laminated over a specially processed image to display different views to each eye, creating a convincing stereo 3D effect so that the element samples appear to stand out from the surface of the paper. On the back of the poster is a listing for each element that includes: name, atomic number, atomic weight, melting point, boiling point in ºC and density in g/ml. Poster dimensions: 59 x 28cm (22” x 11”).

Deionised water (last resort to prevent drying out) • Electrodes should never be stored in de-ionised water, unless as a last resort to prevent drying out, testing sample or solvents • Electrode tips should always be rinsed after use • If electrodes need cleaning physically, use a soft tissue and mild detergent or propan-1-ol, (PH25000) • Regularly inspect electrode glass for cracks or chips; if any are present, replace the electrode • It is not unusual for electrodes to have salt deposits present - these will disappear when rinsed • If bulb becomes dry during storage, soak in storage solution, pH 7 or pHÂ€4 buffer for at least an hour prior to use Please Note: most manufacturers of pH electrodes will not guarantee them for more than 3 or 6 months.

Quickfit/Jointed Glassware 14/23 Single Joint Set (‘BU/M Set’)

Jointed Glassware Sets Micro Scale Kit The Quickfit® Microscale Chemistry Kit was designed to perform organic chemistry experiments, but on a much smaller scale. This reduces your cost of everything involved - smaller amounts of reagents, lower disposal costs and less clamping equipment. Most standard organic chemistry sets may be performed using this set. The main benefits are: cheaper (reduced solvent costs), safer (smaller amounts of chemicals and no Bunsen burners required), quicker (reduced times for experiments), versatile (many assemblies can be constructed - reflux, distillation, fractional distillation etc.) and easy to assemble (combination of standard Quickfit® ground glass joints and sealing ‘O’ rings and plastic screwcaps). Dimensions (L x W x D): 40 x 25 x 20 cm (unpacked). Contents: • Air condenser • Drying tube • Still head • Jacketed condenser • Thermometer adapter • 25 mL Pear shaped flask • 10 mL Pear shaped flask • Bag of spare caps, seals and ‘O’ rings • 25 mL Round bottom flask • 10 mL Round bottom flask • 10 mL Erlenmeyer flask • 25 mL Erlenmeyer flask • Receiver

These sets have been designed to cover the essential requirements for the teaching of organic chemistry in schools and colleges, and are difficult to beat for versatility. The sets, made from borosilicate glass, comprise nine items of glassware housed in a foam insert within a cardboard box (Value Version) or polystyrene insert within a Gratnells tray (Standard Version). Items included are: • Air Leak/Steam Inlet tube • Still Head • 50 mL Dropping Funnel • Screw thread Adapter • 50 mL Pear Shaped Flask • Receiver Adapter • Liebig Condenser • Stopper • Thermometer

QUICKFIT & TIMSTAR JOINTED GLASSWARE Quickfit is regarded as the ‘Premium’ jointed glassware and offers the best overall quality. Timstar jointed glassware is considered to be a ‘Standard’ quality equivalent, offering good quality at a more affordable price. The two ranges are compatible with each other. A Socket is a part that has other pieces fitted into it - usually located at the top. A Cone is a part that fits into other pieces (sockets) – usually found at the bottom. A Joint is like a cone but situated on a side arm or side fitting. Explanation of socket/cone/joint sizes, using examples: A socket, size 14/23: This means that the widest Internal Diameter (ID) of the socket– the top of the socket - is 14mm and the length of the socket (the actual ground glass part) is 23mm. A cone or joint, size 24/29: This means that the Outside Diameter (OD) of the widest point of the cone or joint (i.e. the top of the ground glass part) is 24mm & the length of the cone or joint (the actual ground glass part) is 29mm. A cone or joint, size 19/26 will fit into a socket size 19/26, and so on.

Ideal set for basic organic chemistry. 14/23 joint size. Set comprises: • Leibig Condenser • Air Leak Tube • Receiver Adapter • 100 mL Separating Funnel • 50 mL Round Bottom Flask • 100 mL Round Bottom Flask • 250 mL Round Bottom Flask • Reduction Adapter • Multiple Adapter • Receiver Adapter • Stillhead • 250 mL Conical Flask • Thermometer Pocket • Stoppers

THE SMARTQ DIFFERENCE Beneath SmartQ’s simple and bright exterior is a revolutionary architecture that dramatically enhances the intelligence, accuracy and value of the entire range of sensors. Among many of the remarkable improvements of the SmartQ design is the incorporation of a microprocessor that enables the production team to individually calibrate every single sensor digitally. You willbe astounded by the accuracy and reliability of the sensors

Accelerometer The accelerometer is an electromechanical device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or dynamic - caused by moving or vibrating the accelerometer. There are 2 accelerometer sensors, one recording accelerations to a maximum of 10g and one recording accelerations to a maximum of 40g. The lower range sensor can record acceleration in one of 3 axis or the resultant force of the 3 axis. It will also measure vibration forces and angle. The higher range sensor is restricted to 2 axis and resultant forces of both axis. Both sensors will show the acceleration as multiples of g or as ms-2. Low g Accelerometer Ranges: • ±2.5g 3 axis (xyz) • ±10g 3 axis (xyz) • ±25ms-2 3 axis (xyz) • ±100ms-2 3 axis (xyz) High g Accelerometer Ranges: • ±40g 2 axis (xy) • ±400ms-2 2 axis (xy)

This sensor demonstrates that packaging does make a difference. The upper circular lid casing has been cleverly designed to form sealed chambers using standard laboratory beakers and conical flasks. The casing also provides ports for inserting additional sensors into the chamber such as temperature, pH, and O2. The actual sensing element resides in a vented capsule that protrudes from the lower side of the sensor. The sensor can be set at two ranges enabling measurements from a wide variety of sources.

Force Sensor The Force sensor is supplied with a 20N spring, cushioned and non-cushioned stops, and a hook. It can be clamped to a stand, or attached to the Dynamics System. The hook is used with the spring for simple harmonic motion investigations, with stretchy rubber for bungee jumping, and with a stiff wire for investigating centripetal force in a pendulum. The cushioned and non-cushioned stops are used when investigating collisions and crumple zones, where a car or trolley on a ramp collides with the sensor. Range: • ±50N

Drop & Bubble Counter This sensor offers exceptional value as it performs a dual role. In Chemistry its primary role is as a drop counter measuring accurately the volume of titrant added during a titration. However, this sensor can also be used to monitor bubbles produced during gas production from either a chemical reaction or a biological process. When operating as a drop counter, titrant is uniformly dripped from the supplied reservoir and optically recorded. If desired, the drops can be automatically converted to a volume measurement by following a simple calibration procedure. As a bubble counter, the sensor optically counts the number of bubbles, from either a chemical or biological source, ascending through the plastic tubing. This method is unique in that it accurately measures the range of gas production and is ideal for biological investigations. Ranges: • 0 to 10,000 count • 0 to 120 cm3 volume at a drop rate from 23 to 29 drops per cm3

Rotary Motion Sensor

Speed of Sound Pack

This 8 range sensor is a must for every Physics department. It is highly accurate with an extremely low friction pulley capable of measuring a variety of motions including: pendulum, angular, linear (pulley) and linear (using the Linear Rack accessory). The sensor can be used on its own or coupled with the linear rack and another SmartQ sensor, such as Light Level, to investigate the inverse square law and Young’s slits. If this sensor is used for measuring motion, it is best used with the Dynamics System. The optional accessory kit (see below) widens even further the range of investigations this sensor can achieve. • Pendulum with two adjustable masses. • A 250mm plastic rack which allows for the accurate measurement of linear displacement. It can be used with a Light Level sensor and the Laser Module to accurately measure distance moved in Young’s single and double slit experiments. Similarly, attaching a Magnetic Field sensor, an accurate plot of field strength versus distance can be obtained. • Two discs for studying Angular Momentum. • 11mm Pulley: ±200mm distance • 31mm Pulley: ±2000mm distance • 49mm Pulley: ±2000mm distance • Angular Position: 0 to 360° • Angular Velocity: ±40rads per second • Angular Velocity: ±4 revs per second • Pendulum: ±20° • Linear Rack: ±200mm

The speed of sound pack contains two SmartQ Stethoscope sensors. The difficulty of recording the speed of sound in solids with traditional sound sensors has been with the positioning of the sensors on the test surface, involving clamp stands, sticky tape and pieces of modelling clay. The SmartQ Stethoscope sensor has a shape that allows the sensor to be placed directly onto the surface, no additional apparatus is required. The bell structure of the Stethoscope sensor is more effective in isolating the sounds being recorded from the environment and makes collection of the data simple and repeatable. The support documentation comes complete with tested experiments and full advice on how to use the sensor.

Seismograph Model

Volcanoes & Earthquakes Kit

This simple apparatus allows students to simulate earthquake measurement. Pull the paper as the table is rocked and the pen will record the intensity of the movement. Full teachers notes are provided to ensure students understand the “Richter Scale” and the power of earthquakes. Spare paper rolls are available separately.

Earth is constantly changing - massive pieces of its outer layer are slowly sliding under, over, away from, or past each other. Earthquakes shake the continents and oceans, and volcanoes spew out the molten insides of our planet. By studying these awe-inspiring and devastating natural phenomena, you can learn more about the inner workings of Earth. A full-colour, 48-page experiment manual is included. • Build and erupt a model volcano with plaster-based “lava” that hardens after each eruption. • Volcano can be erupted multiple times - volcanic cone builds up with each eruption, like a real volcano. • Learn about the different types of volcanoes. • Build a working seismograph and simulate earthquakes to see how scientists measure earthquake forces. • Discover plate tectonics, and see how volcanoes and earthquakes are caused by the constant movement of the planet’s parts. • Assemble a plate tectonics puzzle and a geological globe. Play a volcano quiz game to learn about well-known volcanoes.

RICHTER SCALE

Volcano Model Safely demonstrate the principles of volcanos with this realistic model that erupts internally. Eruption and continuous foaming action can be controlled by hand pressure using the unique bottle and tube delivery system. Totally safe with no heat or flames. Provided with comprehensive, fully-illustrated teacher and student literature, as well as step-by-step set up and operating instructions. Dimensions (Diameter x H): 300 x 100mm.

The Richter scale, devised by Charles Richter in 1935, is a quantitative measure of the magnitude of an earthquake. It is a Base 10 Logarithmic scale i.e. each whole number increase corresponds to a 10 times increase in amplitude. For example, an earthquake of magnitude 5 on the Richter scale will be 10 times more powerful than a magnitude 4.

€51,92 ea

EA81320

An increase in magnitude of 1 unit also equates to an approximately 32 times increase in energy released overall during an earthquake. The Amplitude of the Seismic (shock) waves gives a measure of ground movement during an earthquake i.e. the speed or acceleration of sudden ground movements (shaking) – detected by Seismometers, recorded by Seismographs and represented graphically as Seismograms. The Richter Scale has no specified upper limit but is generally quoted on a scale of magnitudes between 0 and 9 (and decimal fractions in between) – due to the fact that no earthquakes have yet been recorded above magnitude 9.

Stream Table This equipment set will help study stream erosion and development, erosion cycles and landform development. Contains a 1,270 x 356 x 76mm heavy duty tray with drain; a 930 x 50mm radius trough, a support to change the tray elevation and siphon tube with clamp. Includes a teacher’s guide.

MAINS VOLTAGE AND FREQUENCY Mains power consists of alternating current (AC), with different voltages and frequencies in different countries. In general, the range lies between 100 and 240 volts, at frequencies of either 50 or 60 hertz (i.e. the number of times the current reverses its direction per second, being 50 or 60). The following mains voltages and frequencies apply: UK 230 V 50 Hz Europe 230 V 50 Hz USA 120 V 60 Hz

242

Previously, Europe operated on 220 V and the UK on 240 V.Â€ However, this was later standardised to 230 V, which is within the 10 % tolerance of both of the old standards, so no change is required in either system.Â€ With the exception of filament bulbs, equipment used in Europe is designed to work on any voltage in the accepted range. Therefore, an appliance rated at 230 V will work on voltages between 220 V and 250 V (which is still in use in some parts of the UK).

LED MAINS LIGHT BULBS – WATTS, LUMENS & COLOUR TEMPERATURE • LED bulbs consume far less energy than traditional incandescent (tungsten filament) or halogen bulbs and, unlike fluorescent and compact fluorescent bulbs and tubes, they do not contain any mercury. Also, they do not take time to warm up to full brightness but glow at full brightness almost as soon as they are switched on • Traditionally the brightness of light bulbs is rated by power (in Watts). However, since the introduction of LED mains lighting, the brightness of bulbs is starting to be rated in lumens - the higher the number of lumens, the brighter the light. This is because LED bulbs use so much less power and it is difficult to know how bright the bulbs are without stating an equivalent rating in Watts, for comparison with the old-type incandescent bulbs. The actual power rating should still also be stated (in Watts) • Please be aware that LED bulbs can only be used with dimmer switches if they are of the dimmable type, and dimmable LED bulbs require a trailing edge dimmer switch Equivalent brightness of different bulb types (approximate only) Tungsten filament (incandescent)

Brightness (Lumens)

As a rough guide: halogen bulbs use approx. 30% less energy than incandescent bulbs; Compact fluorescent bulbs use approx. 80% less energy than incandescent bulbs; LED bulbs use approx. 85% less energy than incandescent bulbs.

Colour Temperature

Colour temperature is used to describe the type of white light emitted. Incandescent bulbs generally emit a ‘warm-white’ light, (yellow-white) and are suitable for less harsh (‘cosy’) house lighting etc. Halogen bulbs tend to emit a cooler white light. Fluorescent lights vary, being internally coated to emit different types of light e.g. warm-white, cool-white or light which is biased towards different parts of the light spectrum (e.g. blue or red, for plant growth etc.). LED bulbs use a colour temperature rating to indicate the type of white light emitted, which is stated in degrees Kelvin (K). LED Colour temperature White light type Equivalent light source

ELECTRICITY & ELECTRONICS Joulemeter, Low Voltage, Premium

Joulemeters Joulemeter, Low Voltage This updated USB version of the low voltage Joulemeter includes datalogging and an improved specification and can be used with or without a computer. Designed to be simple enough to use at KS3, and flexible enough for more advanced use at KS4 and beyond, the Joulemeter simply requires an input supply and a load to be plugged in (e.g. a solar panel and a motor) and the meter will display the values of the power and the energy transferred. For simplicity, the instrument automatically adjusts the display to show suitable units and an appropriate number of decimal places, so that it can deal with a very wide range of values (e.g. for energy, from 100 nanojoules up to 1.75 megajoules). This version of the Joulemeter functions almost identically to the previous version but in addition the meter also keeps a log at the chosen sample rate when the total energy transferred is being measured; the data can then be loaded on to a PC using free minidatalogger software. The function button allows any of four settings to be selected for the required quantity to be measured (energy and time; power; average power; voltage, current and power). • Current range: ±7 A (current can flow in either direction) • Voltage range: ±25 V • Log memory: 2500 samples • Log sample period: 1, 2, or 4 seconds • Powered via USB or using the 5 V mains adaptor (included)

This meter is capable of measuring energies from 1 mJ to 9999 J or power from 1 mW to 200 W in AC or DC circuits. Two ranges selected by a switch labelled mJ/mW and J/W are available. The auto-ranging four digit display will give direct readings of energy or power. The maximum current input is 10 A. All electrical connections are via 4 mm sockets. • Supply voltage: 20 V DC, 14 V AC (rms) • Input resistance: (No load) 2Mâ—¦ • Max load current: J/W range - 10 A, mJ/mW range - 10 mA • Max energies: J range - 9999 J, mJ range - 9999 mJ • Max power: W range - 200 W

Twelve non-electrolytic capacitors selected by a rotary switch mounted on the outer casing. Capacitance values available: 100pF; 220pF; 470pF; 2.2nF; 4.7nF; 10nF; 22nF; 47nF; 220nF; 1µF. Connection by 4mm sockets.

This is a highly useful demo board, it makes the student to understand the charging and discharging of the capacitors. Here the external + 12V DC supply is used for charging the capacitors through the current limiting resistors. The charging curve/time can be viewed on CRO. Once the capacitor is fully charged, it can be discharged with the help of toggle switch (turning towards discharge). Again the discharge curve/time can be viewed on CRO. This phenomenon can also be demonstrated using current meter, only the polarity of motor should be connected properly. Here three different combinations of C & R are provided for observing different wave forms.

Blood Analysis

Forensics Using Simulated Blood

Chemiluminescence In Blood

Though the use of blood type in a forensic investigation is not enough to prove guilt, it may aid in exonerating a potential suspect. In this activity, students act as lab technicians and assist investigators by examining evidence collected at a crime scene. Students first use a presumptive blood test to determine if a substance on a stained piece of cloth may be blood, and then determine the blood type of a sample collected at the scene. Students then compare their results to those of samples provided from two suspects. Kit contains enough materials for 10 groups. Teacher’s Manual and Student Study Guide copymasters are included. Kit includes: • 40 Blood typing trays • 10 Cotton swabs • 1 Cloth • 1 bottle 70% ethanol • 1 bottle Blood detection reagent #1 • 1 bottle Blood detection reagent #2 • 4 Simulated blood samples: Victim, Suspect #1, Suspect #2, Crime Scene Evidence • 1 bottle Simulated anti-A serum • 1 bottle Simulated anti-B serum • 1 bottle Simulated anti-Rh serum

Crime scene investigators examine the scene of a possible violent crime for evidence, such as fingerprints, hair, fibre, etc. After collecting the evidence, they notice there is no visible blood. Someone sprays the area with a liquid then turns out the lights. A strange, faint glow appears in certain areas of the scene. Learn how Luminol is used in scenes like this everyday. The special Luminol formulation does not require a separate hydrogen peroxide catalyst. Simply re-hydrate and use with the simulated blood haemoglobin to show your class. This activity includes an instruction manual with suggested activities. There is enough material for several demonstrations. Kit Contents: • 1 bottle Luminol • Re-hydrating Solution • 1 bottle Luminol powder • 1 bottle simulated blood haemoglobin

Forensic Chemistry of Blood Types Blood typing is a method of classifying blood based on the presence or absence of specific proteins (erythrocytes), on the surface of red blood cells. Blood type, an inherited characteristic, is valuable to know in that it affects medical procedures, such as surgery and transfusions, paternity testing, as well as serving as evidence in criminal investigations. Determining blood type can help provide supporting evidence or eliminate a possible suspect’s involvement in a crime. This activity includes a teachers manual and student guide and analysis copy-masters. There is enough material for 15 groups. Note: This activity uses Innovating Science Simulated Blood and is safe for classroom use.

It allows the visualisation of latent prints which otherwise may go undetected when using conventional processes. Suitable for either rough or contaminated surfaces or multi coloured surfaces where it may not be possible to choose a conventional powder which separates the latent print from its background. Easily applied with a soft brush, this powder fluoresces at slightly different wavelengths to provide a choice when dealing with problematic backgrounds.

Bench Mounted Fume Cabinets The TechFlo range of bench top air extraction cabinets offer an excellent and more versatile alternative to full sized fume cupboards.They are not intended as direct replacements for fume cupboards in all aspects, but offer a more affordable alternative for certain applications. They are suitable for use with organic chemicals, smoking experiments, microbiology and any lower-level fume and dust experiments, but not suitable for use with chlorine, bromine, hydrogen chloride, sulfur dioxide etc.These units are UK designed and manufactured to offer a storable plug-andplay alternative when a full size lab fume cupboard is impractical or too costly, but where contaminant capture is necessary to meet Health and Safety standards and legislation. They are ideal for reducing risks to health posed by monomers, adhesives, hazardous powders and particulates, resins, solvents etc. The easily accessible hoods and shields feature service access ports for balances and equipment. Their convenient size, ability to offer first class air filtration or extraction in such a compact system, and ability to be moved and/or stored easily means they can be a valuable tool within the education sector.

BUNSEN BURNER INFORMATION The following information refers to our Premium Range of Bunsen Burners ONLY Our Premium Range burners are constructed using a heavy pressure die-cast base, which is finished in a chemically resistant blue acrylic paint and nickel plated brass chimneys. All burners are factory tested for flame quality and leakage before packing, using the standard gas pressure and specified gas type for each burner. Base diameter: 80mm. Natural Gas Burners

Typical flame temperatures with the air inlet open (‘blue flame’) will be 900 to 1000˚C. This temperature is achieved at the tip of the blue flame. Typically the flame temperature with the air hole closed (‘yellow flame’) will be 750 to 800˚C. A yellow flame is not only cooler but also ‘dirtier’ than a blue flame and is likely to coat heated objects with a black carbon deposit. The temperatures achieved depend on the mains gas pressure and chemical composition of the gas. Standard mains gas pressure in the UK is 20millibars (mb). LPG Burners These burners are designed to be used with propane (at a gas pressure of 35mb) or butane (at a gas pressure of 28mb). The appropriate pressure reduction valve must be fitted to gas cylinders or tanks. Typically, the flame temperatures reached (with air inlet fully open) are rather lower than those achieved when using natural gas, being in the range 850 to 950˚C. Due to the nature of L.P.G. gases, all L.P.G. burner jets are sealed with a jointing compound to prevent leakage. If for any reason a burner jet has to be replaced, a jointing compound MUST be used.

FILTER PAPER GRADES Timstar offers a range of cellulose filter papers suitable for qualitative use, with Whatman and more economical unbranded types available. The table below refers to Whatman papers and provides a brief summary of the properties of different grades. However, many other branded and unbranded types are graded with reference to the equivalent Whatman grades. WHATMAN GRADE

RETENTION* SIZE, MICRONS (µ)

FLOW RATE# (FILTRATION SPEED)

NOTES / TYPICAL USES

Student Grade (grade 91)

10 µ

Medium/fast

Creped and wet strengthened but manufactured to less critical standards

Grade 1

11 µ

Medium

Most widely used grade for general purpose medium flow applications e.g. Separating liquids from solids

Grade 2

8µ

Medium

More absorbent than grade 1 but slightly slower flow rate. Uses include holding soil nutrients in plant growth trials

Grade 3

6µ

Medium

Twice the thickness of grade 1, giving higher wet strength, so more suitable for use in buchner funnels. Also high absorbency (useful as sample carrier)

Grade 4

20-25 µ

Very fast

Excellent retention of coarse particles and gelatinous precipitates

Grade 5

2.5 µ

Slow

Capable of retaining the fine precipitates encountered in chemical analysis. Excellent clarifying filter for cloudy suspensions and also for water and soil analysis

*refers to size of particles retained by the paper # refers to liquid flow rate through the paper

Buchner Funnels

Diameter 43 mm 55 mm 70 mm

Rubber Cones For use with Buchner Funnels as an alternative to boring a large hole in a rubber bung. The seal between the Buchner funnel and flask forms around the tapered base of the funnel and not the stem. It is therefore necessary to select a cone that fits the neck of the flask and not the funnel stem.

The medium and larger rubber bungs (stoppers) with holes have approximately 5mm diameter holes (small sizes have approx. 3mm diameter holes). The best size glass tubing to fit into these is 6mm outside diameter as this gives a tighter fit that will not leak. If the glass tubing is too tight to fit into the bung easily, a small amount of washing-up liquid applied to the end of the tubing will make fitting much easier. Rubber tubing with a 5mm bore (N5) fits nicely onto 6mm OD glass tubing, for connection purposes.

Test Tubes

TEST TUBE GLASS TYPES SODA GLASS test tubes are suitable for general laboratory work and can withstand moderate warming (e.g. in a water bath) but NOT direct heat. They are an economical choice for situations where direct heat is not involved. NEUTRAL BOROSILICATE GLASS test tubes can withstand moderate temperature changes but should not be used straight from cold to a hot Bunsen flame without pre-warming first (e.g. by moving tube in and out of a Bunsen flame). These glass tubes have good chemical resistance and are a cheaper alternative to borosilicate glass, when only gentle heating is required. BOROSILICATE 3.3 GLASS test tubes are suitable for most laboratory applications and may be used for heating samples up to boiling point etc. This glass type has very good heat and chemical resistance. CARE! With all test tubes and other types of glassware, continuous intensive heating of the same spot will result in softening and deformation of the glass, regardless of glass type or brand.

Partial immersion (PI) thermometers are designed to be immersed in the test liquid up to a line marked at (usually) 76mm from the base of the thermometer. Total immersion thermometers should be immersed in the test liquid up to the top of the liquid column (i.e. the meniscus) or can be completely immersed in the liquid/gas (also known as Complete Immersion).

An explanation of why laboratory thermometers can appear inaccurate when measuring water boiling.* Water boils at 100°C only under controlled laboratory conditions. To accurately test a thermometer at 100°C in a UKAS Laboratory, our supplier uses an oil bath controlled by a calibrated master platinum resistance thermometer, and controls environmental issues such as ambient temperature, pressure and humidity with air conditioning and conversion tables. This situation is impossible to replicate when boiling water in a beaker in a classroom environment. • Tap water contains impurities which will elevate or depress its boiling point. • Atmospheric pressure has a similar effect. • It is necessary to know whether the thermometer is a partial or total immersion model and to use it correctly; for instance, the emergent stem of a partial model when exposed to steam will be heated inappropriately and consequently over-read. Thermometers are designed to be at their most accurate at the mid range position. Therefore, if 100°C is the important temperature, the appropriate model would be one covering -10/150°C or -10/200°C, rather than the usual -10/110°C types found in schools. In practice, rather than attempting to prove that water boils at 100°C, teachers could use the visible discrepancy apparent during classroom experiments to illustrate the effects of the factors listed above! * Information provided courtesy of Brannan & Sons Ltd.

Object There are several factors to take account of when using an IR thermometer it is not as simple as pulling the trigger and reading the measurement. Reflected, transmitted and emitted energy need to be accounted for as well as spot size and emissivity.

INFRARED THERMOMETER EMISSIVITY The spot size is a ratio of distance The spot size is a ratio of distance from IR from IR thermometer to object thermometer to object being measured. being measured. Spotsize size Spot IRIRThermometer Thermometer

Distance Distance

Emissivity is an objects ability to emit radiated heat. The scale ranges from 0.1 to 1.00 and takes into account the objects reflective nature, colour and surface finish. 0.1 is for a polished reflective surface. 1.00 is for a flat black surface. Emissivity can cause an error of up to 30% in the accuracy of a measurement. The easiest way to overcome this is to paint a small piece of masking tape matt black and apply it to the surface of the object being measured.

MICROSCOPES ANNOTATED DIAGRAM OF A ‘TYPICAL’ MICROSCOPE

EYEPIECE Typically x10 widefield magnification.

EYEPIECE TUBE

ARM

HEAD (TURRET)

NOSEPIECE Revolves and holds objective lenses. OBJECTIVE LENSES Typically x4, x10 and x40 but may have x100 for oil immersion.

STAGE STOP If present, located at rear of stage.

STAGE May be fixed or mechanical.

STAGE CLIP Holds slides in place.

CONDENSER If present, to focus light on specimen.

COARSE FOCUS ADJUSTMENT

DIAPHRAGM Controls amount of light to specimen. May also have filter fitted.

FINE FOCUS ADJUSTMENT

ILLUMINATION May be light source or mirror.

BASE

LIGHT INTENSITY CONTROL

GLOSSARY BASE

The base normally contains the illumination system CONDENSER

MECHANICAL STAGE

The condenser consists of a lens or set of lenses that focus the light onto the specimen. There are different types of condenser. The stage condenser N.A 0.65 incorporated in the stage. The Abbe condenser N.A 1.25 this is under the stage and is able to focus light.

A mechanical stage may be fitted or supplied with the microscopes and retains the prepared slide. Mechanical movement allows the slide to be manipulated in ‘x’ and ‘y’ directions.

DIAPHRAGM

Applies to objectives and condensers. This is a function of resolution.

There are different types of diaphragm used in microscopes. The disc diaphragm is a revolving plate with a series of different sized holes fitted beneath the stage. The iris diaphragm is used with the Abbe condenser: a set of interlocked leaves that can be adjusted to improve contrast.

NOSE PIECE

DIN STANDARD

This stands for Deutsche industrie Numer (an industry standard). EYEPIECE

A primary image is formed by the objective lenses: the eyepiece forms a secondary image, which is what you view. Two types of eyepieces are commonly available. Widefield – large field of view. Huygenian – narrow field of view, graticules can be fitter to appropriate eyepieces. The eyepieces fit onto the eyepiece tube or ocular tube. FIELD OF VIEW

The area which is seen through the eyepiece when the microscope is in focus. FOCUSING

There are two types of focusing mechanisms. Rack and pinion – separate coarse and fine focusing controls. Coaxial focusing – comprising both the coarse and fine focusing controls around a common axis.

N.A NUMERICAL APERTURE

Accepts the objectives. The nosepiece rotates the objectives that provide the view of the specimen. The nosepiece of the microscopes may hold 3 or more objectives. OBJECTIVE LENSES

The main objective lenses are 4x, 10x, 40x (spring loaded) retractable and 100x (oil immersion) retractable. Objective lenses will be engraved with magnification, numerical aperture, tube length and cover slip acceptable thickness. OBJECTIVE LENS TYPES

Achromatic objectives are standard objectives. Other are improvements, e.g. ASC (Achromatic Superior Contrast) or plan Achromatic. The terms refer to optical correction. OIL IMMERSION OBJECTIVE

The 100x objective is lowered in to a drop of immersion oil placed on the slide. Oil immersion lenses should be used in conjunction with an Abbe condenser. The oil is the same refractive index as the objective lens and cover slip. PARCENTERED

Applied to each objective viewing – the same centre point in turn. PARFOCAL

The ability of the microscope to stay in focus when the objectives are changed. Applies when high magnification to low magnification is selected.

HEAD

RMS

Assembly that hold the eyepiece(s). this may be monocular, tutor, binocular or trinocular. The head is capable of rotation through 360 degrees.

Royal Microscopical Society. RETRACTABLE OBJECTIVE

ILLUMINATION

The high power objective lens is spring loaded and will retract protecting the prepared slide from damage.

Illumination can be provided in several ways. • Mirror – a plano-concave mirror situated on the base which collects light form a lamp or neutral light and then adjusted to give the best illumination through the specimen. • Bulb – a mains or low voltage lamp either tungsten or halogen generally adjustable fro brightness to illuminate the specimen. • Fluorescent – fluorescent illumination gives an even white and cool light to the specimen. • LED – a cool even light source very close to natural light. No issues regarding heat on specimens.

SLIP CLUTCH

The slip clutch prevents the gears being damaged if you try to rack further than the normal stop position. STAGE

This is the flat, black table where the prepared slide is held in place by the stage clips. An adjustable stage stop protects slides and microscope. STORE CLIPS

The clips that hold the slide in place on the stage.

MAGNIFICATION

WORKING DISTANCE

Total magnification is the eyepiece magnification multiplied by the objective magnification.

The distance between the top of a specimen and the bottom of the objective lens when the sample is in focus.

These Bright-Line (Rhodium coated) glass Haemacytometers are designed for accurate counting of cells in blood or other fluids, with one-piece glass construction, an H-shaped moat to form two counting areas (plateaus) and a “V” slash at the loading side of each plateau. Each plateau features enhanced Neubauer rulings, the ruled surface being 0.1 mm below the cover glass, limiting the volume of blood or fluid over a square mm to 0.1cu.mm and over each of 400 squares (within the central square mm) to 0.00025 cu. mm. Contact of the flat, polished cover glass surfaces with cover glass supports produces an exact volume of fluid over the counting area. The difference in surface tension characteristics between the metallic surface on the chamber and the polished cover glass assures smooth capillarity for precise loading and more even cell distribution. Supplied as a double chamber with two cover glasses or a kit which includes a double counting chamber, cover glasses and red and white pipettes, all in a protective case. Spare/replacement glass cover glasses are also available, as a pack of 2. • Bright Line (Rhodium coated) counting chamber • Improved Neubauer ruling pattern • Cell Depth: 0.100 mm ±2 % • Volume: 0.1 µL To clean the counting chamber after use: remove the cover glass and clean with water or a mild cleaning solution (e.g. 10% bleach solution). Dry the counting chamber with a soft cloth/wipe, or rinse with acetone.

Atoms & Nuclei Radiation Film Badge (Dosimeter)

Atoms “Proton” And “Neutron” Demonstration This set is designed to demonstrate the stabilizing effect of neutrons on the atomic nucleus. The “protons” are made of disc magnets while the “neutrons” are made of browned iron discs. The “protons” will, because they are magnetized, repel one another when placed on a flat surface or overhead projector. The stabilizing effect of the “neutrons” is illustrated by placing them between the “protons”, thereby eliminating the repulsive force. The “protons” are supplied with a red marking, the “neutrons” with blue. Supplied as single pieces.

This apparatus has been designed as a means to demonstrate a chain reaction, using ordinary matches. The apparatus consists of an aluminium plate with holes and a mounting rod. One side of the plate has a level surface but the other side has concentric protective channels milled out of the solid aluminium. Six metal pins are included for damping the chain reaction. Ordinary matches are required for the demonstrations but are not supplied as standard. Experiments should preferably be carried out in a fume cupboard, due to amount of smoke generated by the matches burning. Please note: each experiment uses approx. one small box of matches. The apparatus can be used to demonstrate: An uncontrolled chain reaction; a controlled chain reaction; a partly controlled chain reaction. Replacement metal pins are available separately.

Radiation Film Badge Dosimeters are routinely used by workers to monitor radiation exposure and these badges can be opened to show the different types and thicknesses of filters contained within. The badge has six filters: • An open window which allows all incident radiation that can penetrate the film wrapping to interact with the film. A thin plastic film which attenuates beta radiation but passes all other radiations •A thick plastic filter which passes all but the lowest energy photon radiation and absorbs all but the highest beta radiation. •A dural filter which progressively absorbs photon radiation at energies below 65 keV as well as beta radiation. •A tin/lead filter of a thickness which allows an energy independent dose response of the film over the photon energy range 75 keV to 2 MeV. A • cadmium lead filter where the capture of neutrons by cadmium produces gamma rays which blacken the film thus enabling assessment of exposure to neutrons. Please note that these badges are not functional, and are supplied without film. They are for demonstration purposes only.

The Protactinium Generator is ideal for demonstrating radioactive decay. The half life of the isotope is short enough that students can complete the decay curve within a single lesson and is perfect for use with a datalogger and GM tube sensor or a standard GM tube and counter. The generator is completely sealed in a leak proof enclosure and consists of uranyl nitrate and an organic solvent. These settle into two distinct layers but when shaken together react and produce a short term burst of beta radiation with a half life of the order of about 1 minute. This can be observed using a GM Tube with either a counter or datalogger. The generator comes complete with an SDS and has a recommended storage period of up to 8 years. Specifications: • Radioactive Half Life: 70Â€s • Experiment Time: 5 to 10 minutes • Radiation Type: Beta Decay of Pa234 • Maximum Product Lifetime: 8Â€Years • Active Ingredient: Uranyl Nitrate

Frederiksen Spark Detector

Spark Discharge Apparatus

The Alpha particle Spark Detector from Frederiksen has been developed to enable visualization of alpha particles. The apparatus can be likened to a GM tube, but using atmospheric air instead of the diluted quenching gas in the tube. When alpha particles ionize the air in the spark gap of the detector, bright sparks can be both seen and heard. The apparatus incorporates a transparent lid, which allows clear observation of the sparks. The detector requires connection to a safe high voltage (EHT) power supply with a voltage range of 0-5 kV or 0-6 kV. The apparatus can be safely used directly on a bench top or table and includes a removable threaded steel rod for mounting the unit on a radioactivity bench (RA95610) or squat retort base with thumbscrew (ST96274). • Gives clearly visible and audible response to alpha radiation • Demonstrates the ionization of air by alpha particles • Detects alpha radiation from radioactive minerals or radioactive sources • Allows study of range in air & shielding by different materials

An instrument useful in showing the random nature of radiation, it produces spectacular bright sparks when alpha particles are ionised between the electrically charged circular wire grid and steel electrode.

Muons

A pack of five 148 x 148 x 3 mm steel plates, for use as replacement or additional plates with the Muon Observatory.

Muon Observatory Every second, each square meter of the Earth is hit by some 10,000 particles originating from cosmic radiation. Most of these are muons produced in the uppermost part of the atmosphere, where even more energetic particles collide with air molecules. The purpose of the muon observatory is to facilitate the study of these particles. Muons occur as both positively and negatively charged particles. A muon is approx. 200 times heavier than an electron. Muons are unstable with a half-life of 2.197 µs.

Shower Mode The particles from the cosmic radiation often spread out their energy in a shower of secondary particles, which in special cases can be enormous and hit an area of several square kilometres of land surface. In the shower mode setup, a shower is recorded as a coincidence event from three GM tubes arranged in a triangle. This geometry ensures that no single particle can be detected in all three tubes. Evidence of showers may be facilitated by allowing the radiation to pass through something that is slightly denser than air – e.g. a number of steel plates.

Telescope mode In telescope mode two (or three) GM tubes are arranged in a line, and if a muon passes through all tubes in the setup, a pulse is output from the coincidence box. Placing steel plates between the tubes ensures that only very high-energy radiation is recorded. The third GM tube is used if you want additional suppression of random coincidences. The telescope can be set at different angles relative to vertical. Measurements To register coincidence between two or three GM tubes, a Coincidence Box (RA170505) is required. The output from the coincidence box goes to an Electronic Counter (TI170300), which is set to count with manual start and stop. Contents Muon observatory 25 x 3 mm thick steel absorber plates Also required: • Coincidence Box (RA170505) • Extra sensitive (large area) GM tubes x 3 (RA95592 x3) • Please note: identical detectors must be used • Electronic Counter (TI170300) Optional • Additional absorber plates (RA170502) - up to a total of 40 (max.)

Coincidence Box The coincidence box is used for the detection of simultaneous events in a GM tube and can be used in nuclear physics and in the study of cosmic radiation. It is required in order to use the Muon Observatory correctly. The output of the box sends a pulse to an external counter when two (or three) of the inputs receives a pulse simultaneously (in reality this means within 1 microsecond). The coincidence box can use both conventional GM tubes with BNC connectors and GM tubes with 6 mm Jack plugs, provided that the detectors are identical. Each of the three inputs can be enabled or disabled by means of a switch. The device is powered by a mains adapter (included). The output pulses are registered by a GM counter (RA67530) or the Electronic Counter (TI170300). Comprehensive instructions are included.

Electron Diffraction Tube The electron diffraction tube illustrates the wave nature of electrons by allowing observation of interference caused by a beam of electrons passing through a polycrystalline graphite target on to a fluorescent screen. The wavelength of the electrons can be calculated for various anode voltages from the radius of the diffracted rings and the distance between the crystal layers in the graphite. The electron diffraction tube is a highly evacuated tube with an electron gun consisting of a pure tungsten heater filament and a cylindrical anode all contained in a clear glass bulb. The electrons emitted by the heated cathode are constrained to a narrow beam by an aperture and are then focussed by means of an electron-optical system. The resulting tight, monochromatic beam then passes through a micro-mesh nickel grating situated at the aperture of the gun. Onto this grid, a thin layer of polycrystalline graphitised carbon has been deposited by vaporisation. This layer affects the electrons in the beam much like a diffraction grating. The result of this diffraction is seen in the form of an image comprising two concentric rings that become visible on the fluorescent screen. A spot resulting from the un-deflected electron beam continues to be visible at the centre of the rings. Also requires an EHT power supply. Specifications: • Max. filament voltage: 6.3 V AC • Max. anode voltage: 5 kV • Anode current: approx. 0.1 mA at 4 kV

The diode gun, a tungsten wire “hairpin” filament and a cylindrical collimating anode, projects a narrow beam of cathode rays into the evacuated experimental zone. This beam traverses the sphere to impinge on the luminescent screen in a spot about 4mm in diameter. The narrow beam may be deflected in a vertical plane to enter the Faraday cage by using Helmholtz Coils. A further and horizontal deflection can be obtained using an Auxiliary Coil, thereby constructing a simple cathode ray oscilloscope. All connections are made on the Universal Stand.

Fine Beam Tube (Neon-Filled) with Connector Base The Fine Beam Tube is used for investigating the deflection of cathode rays in a uniform magnetic field produced by a pair of 300mm Helmholtz coils. In addition, it can also be used for quantitative determination of the specific charge of an electron e/m. Located inside a glass bulb with a neon residual gas atmosphere is an electron gun, which consists of an indirectly heated oxide cathode, a Wehnelt cylinder and a perforated anode. The gas atoms are ionised along the path of the electrons and a narrow, well-defined, luminescent beam is produced. Incorporated measurement marks facilitate a parallax-free determination of the diameter of the circular path of the beam deflected in the magnetic field. The Fine Beam Tube is mounted on a base with coloured connectors. In order to protect the tube, a protective circuit is built into the base, which shuts off any voltage in excess of the base’s pre-set cut-off voltage. The protective circuit prevents excessive voltages from damaging the heater filament and ensures a “smooth” switch-on response once the voltage is applied. Requires a 0-300 V DC power supply and 300 mm Helmholtz coils. • Filament voltage: 4 to 12 V DC • Filament current: 300 to 450 mA • Anode voltage: 200 to 300 V • Anode current: < 0.3 mA • Diameter of fine beam path: 20 to 120 mm • Division spacing: 20 mm • Tube diameter: 160 mm • Total height incl. base: 260 mm • Base plate: 115 x 115 x 35 mm • Weight: approx. 820 g

PHOTOELECTRIC EFFECT

The work function of zinc is 4.3 eV, which requires light of wavelength no greater than 288 nm to cause photoelectric emission.

Electrostatic Charge Indicator This charge indicator allows for easy, rapid investigation of electrostatic effects. When it is moved towards a charged object, one of the LEDs will light up - red indicates that the object is positively charged, and green indicates a negative charge. When a polythene rod is rubbed using a piece of cloth, for example, the green LED comes on when it is brought near the polythene, and red LED when near to the cloth. This demonstrates how negative charge has been transferred from the cloth to the rod. Requires 1x PP3 9V battery (not included).

Electrometer Used as a picoammeter, this electrometer is useful for photoelectric effect experiments (e.g. determining Planck’s constant) and ionisation experiments when used with the ionisation chamber RA150000. As a nanocoulombmeter, it is possible to determine the capacitance of a parallel plate capacitor EL120700, and measure electrostatic induction in Faraday’s Ice Pail experiment. The instrument’s design almost completely eliminates leakage currents, for increased accuracy. Two 4 mm sockets provide output for connection to a data logger or meter. It uses a 9 volt battery, which gives approximately 25 hours use. • Current ranges: ±5, ±50, ±500 pA • Charge ranges: ±5, ±50, ±500 nC • Output : 4 mm sockets ± 0.5 V FSD

Electric Fields E-Field Apparatus This apparatus allows visualisation of electric fields between various electrode configurations, in a similar way to how iron filings allow visualisation of magnetic fields. It is constructed from transparent acrylic, which allows it to be placed on an overhead projector for class demonstrations but can also be used on a white surface for use with visualisers or for direct observation by smaller groups. In order to create electric fields large enough to influence the particles, a high voltage, low current 2-5kV EHT power supply is required. Apparatus includes electrodes, clear acrylic base with 4mm sockets to clamp electrodes and connect power supply, petri dishes and instructions. Also requires liquid paraffin (PA4452 or PA4454 and semolina (not supplied). Base dimensions (L x W x H): 150 x 150 x 65 mm.

Relay Demonstration

Electromagnet Kit

The Relay Demonstration Unit allows the investigation and study of how a relay functions, in a clear and practical manner. A useful property of this unit is that the circuit powering the coil is easily seen to be completely separate from the circuit switched on by the relay. This is one of the reasons relays are used where a safe low voltage circuit can be used to control a high voltage circuit. When a current flows through the coil an electro-magnetic field is produced. This field attracts the iron armature whose end makes the contact, completing the circuit and illuminating the lamp. When the current is switched off, the contact will open again, switching the circuit off. Specifications: • Control input voltage: 2 V DC • Switched supply voltage: 12 V Max

Current Balance (BIL Coil)

Motor Kit

This current balance apparatus (BIL coil) consists of a printed circuit board coil mounted on a support handle. The board has 2 coils – one with 5 turns and one with 10 turns, rated at 2A. The apparatus can be used to measure the force on a current carrying conductor in a magnetic field. A permanent magnet should be placed on the pan of a digital balance (a yoke with 2 ceramic magnets will work) and the BIL coil mounted in a vertical plane between the magnets. When connected to a low voltage power supply and ammeter, the balance will be deflected and the new reading can be taken. The force on a current carrying conductor and field strength can then be calculated.

This self assembly motor kit is very robust and clearly demonstrates the constituent parts of a DC motor.

Magnetic Field Viewing Film This amazing flexible sheet ‘visualizes’ the direction of magnetic field lines. The sheet is coated with translucent microspheres (hollow capsules) containing very small magnetic nickel flakes suspended in an oil. The flakes inside the spheres align along the field lines when a magnetic field is present. The alignment of the flakes, and thereby the magnetic field direction, is visible because of reflected light from the flakes. Useful for quality control, product demonstration, reverse engineering, and educational purposes. Two types and sizes are available: laminated and non-laminated ‘raw’ film. The laminated film is ideal for student use as it is more durable and less easy to damage. The non-laminated film is great for demonstration purposes as it can be cut to any size or shape as required, is highly flexible and can easily be wrapped around objects. A good example is to wrap it around a copper tube to ‘view’ the progress of a neodymium magnet as it slowly descends through the tube. The film is also useful for viewing complex magnetic pole geometry close to the magnetic poles, although it does require fairly strong magnetic fields.

The kit demonstrates the levitation of a small rare earth magnet above the high temperature superconductor, caused by the partial expulsion of the magnetic flux from the HTSC sample. Liquid nitrogen (not supplied) is required as a coolant, to bring the superconductor below its critical temperature. When the superconductor is cooled, under a weak magnetic field, to a temperature below its critical temperature, it becomes superconducting i.e. loses its electrical resistance. The magnetic field becomes expelled from the superconductor, causing it to become perfectly diamagnetic. At this stage, the sample is said to be in the Meissner state. Please note: liquid nitrogen is required, but not supplied Kit Includes: • Insulated Styrofoam holder • Superconducting HTSC disk • NdFeB rare earth magnet • Tweezers • Instructions, including advice for handling liquid nitrogen

Gauss Guns

Floating Magnets

Magnetic Accelerator Kit (Gauss Gun)

Floating Magnets, Coloured

The gauss gun (also known as a gaussian gun or rifle) is an example of a magnetic linear accelerator and uses powerful neodymium magnets to launch a steel sphere at high speed. Magnets are held in place part way along the tube (using the steel washers provided), with two steel spheres on the ‘downhill’ side. Another sphere is rolled slowly towards the magnets and as it gets closer the magnetic attraction causes the sphere to accelerate considerably, resulting in the sphere impacting with the magnets, transferring energy to the sphere at the opposite end of the magnets causing it to shoot off at high speed (similar to how Newton’s cradle works). Even faster speeds can be achieved by using a series of magnets and spheres. The magnets and steel spheres are contained within a clear plastic tube for safety reasons (neodymium magnets are brittle and can splinter, the spheres can be accelerated with some force). Kit includes 6 magnets and 5 steel spheres, washers and clear plastic tube with rubber end stopper to stop sphere. Instructions for use included.

Plastic coated magnets, comes as a set of five different coloured magnets or a set of three coloured blue & red to indicate polarity. Each set is supplied complete with free-standing rod and presentation box.

Gauss Gun This demonstration of the Gauss gun effect uses a 660 mm long section of acrylic tube to house rare earth (neodymium) magnets and ball bearings. One end is raised slightly to allow the first ball to begin its movement and there is a rubber stopper at the other end to prevent the ball bearings from flying out. The Gauss Gun demonstrates acceleration of a body in a magnetic field and the conservation of momentum, using neodymium magnets to accelerate ball bearings. The moving components are safely enclosed in a clear plastic tube. This apparatus provides great discussion points on the nature and strength of magnetic fields, momentum, conservation of energy etc.

The apparatus consists of a 450 x 28 mm copper tube which has a metal gauze fitted inside, at a pinch point part way up from the base. The tube should be supported by a retort clamp towards the top, away from the heat, and a blue Bunsen burner flame directed into the base and onto the gauze for a few seconds only. Shortly after removing the flame, the tube emits a loud ‘foghorn’ sound as air is drawn up the tube by heat rising from the hot gauze. If the tube becomes too hot it will stop emitting sound, in which case it should be allowed to cool before trying again.

SEP Mini Wind Turbine The SEP mini-turbine can be used to introduce basic principles of a wind turbine. It consists of a small electric motor attached to a propeller and connected to a pair of terminal posts. To demonstrate how the turbine can generate an electrical current, it can be connected to an LED or electric motor. To measure the output, it can be connected to a voltmeter or digital multimeter - the faster the turbine turns, the higher the voltage reading. The mini-turbine can be used to carry out simple investigations into the effects of different wind speeds and angles on output, using a desk fan, for example. The wind speed can be varied by using the settings on the fan. The mini-turbine can be held in the hand or, for a more quantitative approach, held in a clamp stand, which allows distances and angles to be measured more accurately.

The solar thermal collector is used to demonstrate how solar energy can be converted directly into heat energy. The apparatus includes a peristaltic circulation pump, along with an acrylic reservoir with heat exchanger (copper coil). The reservoir can illustrate how the water heater in a house works or, if used without water, to illustrate how a radiator heats up the air in a room. The apparatus can also be used with a halogen lamp as a light source (to replace the sun). Solar radiation is absorbed by the black absorber plate, which consists of a metal plate with attached copper pipes, insulation behind the absorber and a transparent acrylic front plate to reduce heat loss. The black copper pipe mounted on the collector is connected with plastic tubing to the pump and copper coil in the reservoir. The pump circulates water through the pipe and tubes and transports thermal energy from the absorber to the reservoir. When the temperature and amount of water in the reservoir are known, the heat input can be calculated from the temperature rise. The reservoir/storage tank includes a rubber stopper with holes for a thermometer and a thermocouple, for data collection. The collector has a hole at the top to allow the copper pipe temperature rise to be monitored. The solar thermal collector can be set at different angles to ensure the highest possible solar intensity. • Area of the absorber: 29.0 x 29.4 cm = 852.6 cm2 • Reservoir: 94 mm internal diameter, 3 mm wall thickness acrylic • Overall dimensions: 31 x 31 x 6 cm • Water pump: 12 V DC / 1.5 A

Thermal Conductivity Bars

Ice Melting Kit, Advanced

These are safe, clean (no wax) and easy to use. The durable liquid crystal strips embedded in the bars show how a red zone of 40°C moves up the bars. The colours give a dramatic view of conduction and the marked difference in temperature gradients in the bars is also visible. By immersing the heated bars into cold water shows how conductivity applies to heat leaving the metal. The tops of the bars are designed to be touched with a finger tip to reinforce the colour observations.

This advanced ice melting kit nicely demonstrates the thermal conductivity of materials by using different types of metal blocks to melt ice cubes. The kit consists of an acrylic base with sump, an acrylic tube, two cylindrical copper blocks and two cylindrical steel blocks. The apparatus is set up by placing one of the copper blocks on top of the acrylic base. The base has an integral sump, which will contain the meltwater from an ice cube. The acrylic tube is then placed over the copper block, in order to contain the metal blocks and ice cube. An ice cube is then dropped down the tube onto the block and the second copper block is placed on top. Immediately the ice begins to melt, due to the high thermal conductivity of copper (along with a large thermal mass), and in a matter of 10-15 seconds the ice will have melted and disappeared. By repeating the experiment using the steel blocks it can be seen that the ice melts more slowly, due to the lower thermal conductivity of steel. Each experiment can be timed, for a more accurate comparison between the two different metals. The kit also includes two plastic insulating discs, which can be placed between the ice and the metal blocks to show that it is not simply the pressure of the top block which is causing the ice to melt. If repeating the experiment using the same blocks, it is better to allow the blocks to come back up to room temperature first (if repeatable results are required). Contents: • Acrylic base and tube • 2 x 0.5kg copper blocks • 2 x 0.5kg steel blocks • 2 x plastic insulating discs Also required: Ice cubes, preferably quite large.

Drinking Bird A classic toy that is really a heat engine! This simple, inexpensive device demonstrates the cooling effect due to evaporation. Simply duck the bird’s head into a container filled of water to begin the bobbing motion. Subsequently, the bird will continue to drink by dipping its head into the water, so long as there is water in the container. The evaporation of water from the material on the bird’s head cools the vapour of the special liquid inside the bird, which in turn causes a pressure drop in the head allowing liquid to rise from the base. This alters the balance of the bird on its pivot and the bird dips back down into the liquid again to repeat the cycle. Please note: model supplied may differ from the image.

Thermal Radiation Thermopile (Heat Radiation Detector) This sensor is sensitive to electromagnetic radiation in the wavelength region from 0.25Â€µm to 20Â€µm, i.e. from the ultraviolet through the visible to the far infrared. Thus it is sensitive to thermal radiation in the near IR (0.3-3Â€µm) and far IR (3-20Â€µm) regions. Because the sensor uses a black absorbing surface and a thermopile detector, the response of the sensor is uniform over its wavelength range. The output signal is proportional to the incident power per unit area striking the detector surface. The sensor is adjusted so that an output of 4Â€V corresponds to 1000Â€W/m2Â€±3%. The cable is terminated in a 5 pole male DIN connector compatible with the power supply / adapter box below, to provide the necessary 5Â€VÂ€DC bias voltage. When using the battery box an ordinary digital voltmeter, multimeter or oscilloscope can be used to read the output signal.

NEWTON’S LAWS Newton’s laws of motion are three physical laws that together laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to said forces. They have been expressed in several different ways over nearly three centuries, and can be summarised as follows. First law: When viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force. Second law: The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object: F = ma. Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body. The three laws of motion were first compiled by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687. Newton used them to explain and investigate the motion of many physical objects and systems. For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler’s laws of planetary motion.

Forces & Motion Force Board Kit

Forces Force table This Force Table enables demonstrations and hands-on experimenting by students into the parallelogram of forces (vector addition of forces). The apparatus consists of a polypropylene table mounted on three legs, with three free-running pulleys which can be fitted arbitrarily around the edge of the table. The magnitudes of the three acting forces can be altered using the three supplied slotted mass sets. The kit includes: • Graduated scale and rotating protractor • 3 legs • Spirit level • Central locating ring • Thread • 3 pulleys with clamps • 3 mass holders (10 g each) • 3 mass sets (each set comprises 1 x 50g, 5 x 20g, 1 x 10g, 2 x 5 g)

The Force Board is a good way to introduce students to Newton’s Laws and vector addition, demonstrating the principles of the parallelogram and polygon of forces. The board, pulleys and masses (all included) allow for easy set-up of equilibrium conditions and consequent measurement of the forces involved. The background grid helps to visualise the direction of force and thereby to calculate the resultant vector. The back board is bench-standing and hard-wearing, with a printed background grid, and has detachable feet for easy storage. The set includes ball bearing pulleys, three hooks, thread and a mass set. Board dimensions: 40 x 55 cm (W x H)

PARALLELOGRAM LAW OF FORCES

A larger version Force Board, useful for demonstrating parallelogram of forces / relationship between forces acting at a point. The apparatus comprises a sturdy board approximately 60cm x 50cm, 2 x 50mm diameter clamping pulleys, 12 x 50g slotted masses and 3 mass hangers.

The parallelogram law requires the two forces to be adjacent. Another way of constructing the parallelogram is to place the origin of the second vector at the terminal point of the first. Because parallelograms have opposite sides that are congruent, the result remains the same. Although construction and measurement of the resulting vector provides a close approximation to the resulting forces, mathematically, it is possible to solve for the resultant force using either the sine law or the cosine law from geometry. Physics views forces as vector quantities. They have both magnitude and direction. If two forces act on an object in the same direction, the vectors add. When three forces act on an object from multiple directions, the physicist determines the resultant of two forces and repeats the procedure using the vectors for the first resultant and the third force.

The pendulum wave is both attention grabbing, and a great demonstration of simple harmonic motion. The apparatus comprises a row of 15 steel ball pendula of different lengths so that they will swing at a unique frequency. The frame is minimalist in design, so the apparatus can be viewed from the front or side to best effect. Using the supplied wooden board, the pendula are raised to the same height, and then released simultaneously. At first, they will all be in the same position, but as they start to swing out of phase due to their different natural frequency, they will begin to form beautiful patterns, before eventually returning to swing in phase again. Hypnotic to watch, it will leave students asking for an explanation as to how it works! Dimensions (L x W x H): approx. 40 x 15 x 22 cm

Guinea & Feather Apparatus Apparatus to show the equality of acceleration under gravity between light and heavy objects in the absence of air resistance. Comprises a 100 cm acrylic tube with bungs at either end. A valve with stopcock at one end allows a vacuum pump to be attached, and the air evacuated from the tube. Inside the tube is a coin, and a piece of paper (various laws prevent supply of a feather for this apparatus). When air is in the tube, the coin falls quickly but the paper is subject to air resistance and falls more slowly. With the air evacuated, the only force acting is gravity, so the two fall at equal rate, despite the difference in weight.

‘g’ by Freefall Apparatus Kit

Monkey & Hunter

This premium apparatus, from Frederiksen, allows accurate and reproducable free fall experiments to be carried out. The release mechanism at the top sends a start pulse to the timer when the ball is released, and a stop pulse is generated when the ball hits the contact plate at the bottom. • Connections via standard 4 mm safety connectors • No external power supply required so no risk of overheated coils • Four gold-plated steel balls and a ping-pong ball with metal thumb tacks included • Includes a mirror to minimize parallax errors Requires separate timer (FO140110), stand and cables (not included).

This fun and useful apparatus helps to demonstrate the ‘Monkey and Hunter’ experiment, to show how gravity affects projectile motion. The apparatus consists of a projectile ‘gun’ which fires a ping pong ball (‘bullet’) and a model animal (‘monkey’) on an electromagnet release mechanism. The monkey is released at exactly the same time as the ball is fired, so should the gun be aimed directly at the monkey or just below it to allow for the distance it falls? Theory and practice will show that the gun should be aimed directly at the monkey, as both ball and monkey will fall at the same rate due to gravitational force.

Inputs are via DIN 6 pole connectors (for Frederiksen photocells and microphones) or 4 mm safety sockets (for free fall experiments or other equipment). Compatible with the following equipment: • SO150400 microphone • TI170200 photogate • TI170100 speedgate • FO140105 freefall apparatus • Range: 0.03 ms to 27 hours • Resolution: 0.01 ms • 5 digit LED display with floating decimal point • Manually controlled stopwatch option • Accepts start and stop signals from microphones, photocells or any on/off switch connected to the 4 mm sockets • Power: 6 x AA batteries or mains adapter (included)

This simple but effective apparatus demonstrates that two projectiles launched at the same time, but with different trajectories, will hit the ground at the same time due to the force of gravity. In this case, one steel sphere is launched horizontally from a spring-loaded L-shaped arm at the same time as an identical steel sphere is allowed to fall freely from the same height, but vertically. Both spheres will hit the ground at the same time. Launching mechanism is mounted on a wooden block, which can be clamped to a bench top, and comes complete with 2 steel spheres. The wooden block also incorporates an integral storage pocket for the spheres. Dimensions: 180 x 60 x 30 mm.

Frederiksen Speedgate

Millisecond Timer

A double photogate with built-in timer and display, which is capable of precise speed measurements, in addition to all the usual tasks of a single photogate. • Incorporates timer with display – no separate timer required • Easy to operate • Double light barrier – direct readout of speed • Laser optics give high precision measurements • Expandable with external sensors (e.g. microphones) • Use two SpeedGates for all the traditional collision experiments • Several SpeedGates can be daisy chained • Pendulum period mode prevents off-by-one errors • Auto rotating display Speedgate can be used as a stand-alone unit or a pair can be used to carry out all the experiments you can do with two traditional photogates and a universal timer plus much more: with the precisely spaced double laser system you get speed readings without length measurements or calculations. The traditional passage time measurements are still possible, if preferred, for teaching purposes. The display divides into two parts giving you immediate access to all results. An adjacent status area shows when light rays are blocked, the state of external inputs etc. SpeedGate is battery powered so can be used as a stand-alone unit no cables are required. However, the apparatus can also be powered via a USB cable if preferred. It is operated using three pushbuttons, which control primary mode, secondary mode and reset. The reset button also functions as a power switch. The primary and secondary modes each correspond to one part of the display. Suggested experiments: • Kinematics of uniformly accelerated motion • ‘g’ by freefall • Newton’s second law • One-dimensional elastic and inelastic collisions • Mathematical pendulum • Speed of sound (requires 2 x SO150400 microphones) Two SpeedGates can be used for collision experiments; the double display will show the two latest measurements. Connect two (or more) SpeedGates together, using the Speedgate Cable, to measure the time interval between the gates e.g. for acceleration experiments. The whole chain is reset with one button press. The timer functions can even be used with external signals e.g. two microphones (SO86270) and a SpeedGate makes a complete setup for measuring the speed of sound. Easy to work with – the display even orients itself automatically when rotated. The Bundle TI180110 comprises two Speedgate units & a connecting cable.

This timer is most suited for an investigational approach for students to gain a sound understanding of the concepts of time and motion. Two pairs of sockets alternately start and stop the timer, one pair operating in make mode, the other in break mode. The start/stop switches can be either mechanical or electronic. The timer is auto-ranging for ease of use and has a clear 13mm digital display and has a robust metal case with a durable powder coat finish. An illuminated on/off switch is mounted on the rear panel adjacent to a fused appliance inlet. • Electrical Supply: 220-240V AC 50-60Hz • Dimensions (W x L x H): 179 x 190 x 85mm • Mass: 1.6kg • Ranges: 0 to 9.999s; 10 to 99.99s; 100 to 999.9s; 1000 to 9999s • Accuracy: ±0.01%

TI110900

Light Gate (Photo Timing Gate) For use as a light operated timing gate. Comprises photodetector and light source each housed in a robust ABS case spaced 40mm apart on a plastic rod. Light source housing has battery compartment and on/ off switch. Photodetector housing is fitted with a pair of 4mm sockets to allow connection to electronic timers. When the timing gate is switched on it creates a short circuit between the two output sockets, this then becomes an open circuit each time the light beam is interrupted. Consequently the timing gate can be used as a remote switching device in a wide range of dynamics experiments.

PHYSICS Joly’s Bulb, Metal

Gas Laws Boyle’s Law, Improved A much improved version of the Boyle’s Law Apparatus, which is reliable and easy to use. The apparatus comprises a reservoir with a bourdon gauge, connected to a vertical glass tube. The reservoir has a needle valve to control pressure, and a high-quality tyre-type valve for attaching the supplied pump. Air does not escape when the pressure is increased, until the needle valve is opened. The pressure is displayed on a bourdon gauge, which has a transparent back, allowing students to see the internal workings. Pressures of up to 3.5x atmospheric pressure can be measured, which provides a good range of measurements. The tube is of strong construction, and is further protected by a plastic safety screen. It has graduations so that the length of the air column can be measured, and is of uniform cross-section, so the volume of air is proportional to the length of the air column. Unlike traditional Boyle’s Law apparatus, this unit has no rustable materials, so water can be used instead of oil, which offers superior results, as well as reduced hazard and mess. The water is pumped into the tube, and the pressure and volume of air is measured at regular intervals. The inverse relationship between pressure and volume at constant temperature is easily observed.

This 80 mm diameter hollow metal sphere is connected to a manometer (Bourdon) gauge, for demonstrating changes of pressure in a closed volume of air when either heated or cooled. Immersing the ball in a heated water bath or ice bath allows the relationship between pressure and temperature of the enclosed air to be investigated. The metal sphere is more robust than glass versions and responds to temperature changes a little faster.

This apparatus vividly demonstrates the rise in temperature that occurs when a fixed mass of air in a transparent cylinder is compressed by a hand operated piston. A piece of tinder, which is provided, ignites in the transparent cylinder: much as a diesel engine obtains ignition. The cylinder and piston can also be used to demonstrate the effect of decompression, being the immediate lowering of temperature and the consequent condensation of water vapour inside the cylinder - the cloud formed can easily be seen.

Kinetic Theory Model

Ball and Ring

A model that simulates the behaviour of particles in a gas. An electric motor running at 4-12 V DC vibrates a small platform inside a transparent tube, which in turn vibrates several steel balls inside the transparent tube. A lightweight float on top of the balls is held almost stationery by the “pressure” of the steel balls. The “temperature” of the gas can be increased by supplying more power to the motor – an control knob on the base allows this to be varied. The “pressure” of the gas can be increased by adding additional mass on top of the float – cardboard discs can be used for this purpose. The “volume” of the gas is represented by the height of the float. The cross-section of the tube is uniform, so the height of the float is directly proportional to volume. By altering the “temperature” and “pressure” of the gas, ideal gas laws can be demonstrated. Requires a 4-12 V DC power supply, and 2x 4 mm plug leads.

Demonstration Bimetallic Strip

To demonstrate the unequal expansion of two metals by the curvature produced when the bar is gently heated. Comprising two metal bars, steel and brass, riveted together with brass rivets. Fitted with a wooden handle. Not intended for intensive heating. Dimensions (L x W): 200 x 15mm.

This Demonstration Bimetallic Strip consists of a bimetallic strip fixed to a base, with a 12V halogen bulb mounted below the strip. When the power is switched on, the heat produced by the bulb will heat the bimetallic strip causing it to bend upwards, which breaks the circuit and the bulb switches off. As the bimetallic strip cools down it returns to its original shape, thereby completing the circuit again, which switches the bulb back on and the sequence repeats over and over until the power is disconnected. A miniature version of this concept is used in flashing bulbs and Christmas lights. Base Dimensions (L x W x H): 130 x 80 x 30 mm.

Optics Colour Mixing Apparatus

Colour Mixing Multicoloured LED bulb This LED mains bulb uses red, green and blue LEDs in a frosted glass globe to create a diffuse light source of controllable colour. It can be used to show a consumer application of colour mixing principles, and also as a convenient source of coloured light for experiments in reflection and absorption of colour. Supplied with a remote control to choose the colour and select the mode (flash, strobe, fade and smooth). The remote control takes a CR2025 battery (included). • Voltage: 230 V • Power: 3 W • Luminous flux: 70 lm • Fitting: E27/ES

An upright case contains three, high powered, accurately colour matched LEDs, each of which has infinitely adjustable brightness. Also supplied is a large, free standing, primary colour shadow mask, a hand held secondary colour mask and a 12 V plug top power supply. The system allows the teacher to project large primary and secondary colour mixing disks onto any vertical surface and to adjust the colour saturation to mix virtually any colour (how do you produce brown). Unlike other systems the purity of the resulting white is outstanding. The unit is extremely easy to use, is easily transportable and comes with full instructions. The only other requirements are a white wall and a darkened/blacked out room. The system may be used to demonstrate both secondary and primary colour mixing, colour shadows and colour reflection/absorption.

Use the RGB Colour OUR EXPERT SAYS... Changing bulb in a desk lamp to create a convenient, portable source of coloured light, which can be used to light up different objects, and study how they reflect and absorb light of different colours.

Colour Mixing Box This unit contains three coloured light sources (red, green and blue) projected onto a screen in overlapping circles. The unit is selfcontained, meaning no setup is required, and can be used comfortably by 2-3 pupils at a time. The brightness of each light can be controlled independently, allowing any combination of the three. This allows the demonstration of composition of any colour using just the primary colours. Requires 3x AA batteries.

PRIMARY & SECONDARY COLOURS IN OPTICS In Optics (and science in general), Primary and Secondary colours are the colours & colour combinations resulting from emitted light. The Primary Colours (known as ‘Additive’ Primary colours) consist of: Red, Green, and Blue (RGB). The Secondary Colours resulting from combining the Primary colours are: Yellow, Magenta and Cyan. When R+G+B are combined in the correct proportions or intensities, white light should result – although in practice this often appears ‘off-white’.

For information: In Art or Painting, ‘Primary’ and ‘Secondary’ colours are historically different and refer to colours and colour combinations from reflected light. These are: Primary Colours (known as ‘Subtractive’ primary colours): Red, Yellow and Blue (RYB) Secondary Colours: Green, Purple and Orange In the printing industry, the Primary Ink Colours are Cyan, Magenta and Yellow. Along with black, these give the CMYK colour system (‘K’ referring to black or ‘Key’ colour).

Colour Mixing Apparatus, Premium

Newton’s Colour Disc

A powerful and effective colour mixing apparatus, comprising three LEDs (RGB) in a hexagonal housing, which projects a circle of light of each colour, which can be overlapped to show the effect of mixing the colours. The intensity of each colour can be controlled independently using the controls on the housing, or turned off completely. The LEDs are factory adjusted, ensuring a convincing white light in the middle. The 3 watt LEDs are very bright, ensuring the whole class can see. The projected circles can be up to 40 cm diameter. The housing is of robust black aluminium hexagonal construction, with ventilation to ensure the LEDs have a long life. The apparatus does not get dangerously hot. A removable 10 mm diameter rod is included, allowing the apparatus to be mounted in a retort clamp. A 12 V power supply is included. Dimensions: 38 x 14 x 12 cm. Weight: 780 g.

This Newton’s Disc consists of an aluminium plate with coloured segments printed on it. The colours represent the colours of the visible spectrum (red, orange, yellow, green, blue, indigo and violet). When the disc is rotated and the speed increased, the colours start to blur and fuse together and then mix so that the eye, unable to respond rapidly enough, sees this effect as white light. Mounted on base with handle at rear to turn the disc. Weight: 0.8 kg. Dimensions (L x W x H): 250 x 150 x 250mm.

Newton’s Colour Wheel This motorized Newton’s colour wheel is useful for demonstrating that white light is composed of a combination of different spectral colours. Comprises a disc with different coloured sectors mounted on a low voltage (6V DC) motor box with integral 4mm sockets. When the disc is rotated at a fast enough speed the colours merge to form white (usually off-white). Requires a standard variable laboratory power supply (1-6 V DC).

Laser

Multifunction Laser

This laser emits an intense monochromatic red beam of wavelength 630 - 640nm at 0.9mW (Class II operation). Typical beam divergence is approximately 1 millirad. The laser beam can be modulated by applying an external digital or analogue waveform to the 3.5mm jack socket on the rear panel. Alternatively the beam can be modulated by the internal generator which produces 0.1µs pulses at approximately 1MHz. This allows speed of light experiments to be easily performed. The passage of light through light guides and optical fibres can be demonstrated by filling a glass or plastic tube or U-tube with very dilute milk.

This multifunctional laser provides an extremely versatile solution for laser optics. It offers the facility to use a single light beam for laser experiments, a horizontal plane light beam for the study of wave propagation and 1 or 3 light beams in a vertical plane for ray optic experiments. The unit also allows studying transmission through a fibre optic using the modulated input for the laser beam. The magnetised base means it can also be used on magnetic boards, for easier demonstration. Can be powered by 2 x 1.5 V batteries (not included) or mains power adapter (included). Specifications: Wavelength: 650nm Power: 1mW (class II) Modulation: TTL signal (5 V) with 4mm safety plug Power supply: 2 x 1.5 volt battery or mains adaptor provided.

Dimensions (L x W x H): 68 x 120 x 36 mm.

This kit comprises a red laser which attaches and rotates around a graduated plate, which makes it easy to see and measure the incident beam angles for both reflected and refracted beams. It can be used in a vertical plane with the cylindrical tank with water or in a horizontal plane with the glass optical accessories, which are included. Useful to demonstrate: Verification of the Snell’s law of refraction with a semi-circular block or a cylindrical tank; Total or diffuse reflection with a plane mirror; 90° reflections in a 90° prism; Double refraction with parallel faces; Determination of the angle of a prism; Multiple reflections and refractions in a trapezoidal prism.

Determining Wavelength Of Light Apparatus The apparatus is designed to measure the wavelength of light by studying the interference pattern from a double slit. The equipment is well suited for student lab exercises. The device contains a 12 V / 15 W festoon lamp with a holder for colour filters and a millimetre scale with moveable markers. The light is viewed at a distance of about 3 metres through a double slit. The viewer directs a co-worker to adjust the markers so that the distance between them corresponds to 10 interference maxima. Afterwards the precise distances can be measured and the wavelength of the light can be calculated. Red and blue colour filters and a double slit are provided. Power source required: 12 V AC/ DC, 1.3 A

This apparatus is designed to determine the approximate value of Planck’s constant, using a range of LEDs of known wavelength, to allow the electron/photon energy to be calculated. There are 7 LEDs, covering the light range from deep blue at 470 nm to near IR at 940 nm, mounted on a box with 4 mm sockets for attachment to a voltmeter and ammeter for voltage and current measurements. By monitoring the voltage at which each LED just begins to emit light, a graph of energy input as a function of light emitted frequency can be plotted and an approximate value of Planck’s constant can be deduced. Requires a 9 V DC power supply (standard lab power supply).

Frederiksen Planck’s Constant Apparatus

Fibre Optic Cable, Unsheathed

This apparatus is designed for the determination of Planck’s constant. The knee voltage in the characteristic curve of a light emitting diode (LED) is closely related to the energy of the emitted photons. By graphing knee voltages for a range of LEDs as a function of the frequency of the emitted light, a linear relationship is established. The LEDs used emit UV (ultraviolet), NIR (near infrared) and three wavelengths in the visible region. The LEDs have been carefully selected to emit light within a narrow, well-defined wavelength interval. Either the built-in 9 V block battery or an external 9-12 V DC adapter can be used as power supply.

This unsheathed cable illustrates the magical qualities of optical fibre light transmission. Dimensions (L x Dia.): 1 metres x 1mm.

Speed of Light Frederiksen Speed of Light Apparatus Watch the progressive delaying of light pulses as they travel longer and longer. Demonstrate that Light has a finite speed Determine the speed of light Fast and easy setup Direct time-of-flight measurements with pulses of light Experiments can be performed easily in a standard classroom Very short but powerful pulses of light are emitted from the box. When the light pulses hit the special retroreflective foil of the reflector they are directed back towards the source – with no need for tedious adjustments. Via a beam splitter, the light pulses finally hit a high speed photodiode, converting them into electric pulses to be displayed on an oscilloscope. A separate synchronization signal marks the time of pulse emission and constitutes a reference for timing the pulses. Please note: The speed of light apparatus also requires an oscilloscope. We recommend using the apparatus with our 60 MHz PC Oscilloscope, EL170110, as this has a high bandwidth and also allows projection onto bigger screens via a PC. The apparatus can also be used with most other oscilloscopes and PC oscilloscopes. A bandwidth of at least 25 MHz is recommended, along with an adequate sample rate to display the signal on a 5-10 ns/div time scale. Coax cables, user manual and mains adapter are included.

PHYSICS Polaroid Stress Analyser

Newton’s Rings Newton’s Rings Apparatus This simple apparatus nicely demonstrates Newton’s rings. It consists of a slightly convex lens, mounted against a flat glass plate. Interference fringes, known as Newton’s rings, can be observed as a series of light and dark concentric circles around a central dark spot where the lens and glass plate meet. This phenomenon is usually observed using a monochromatic light source such as a sodium lamp. The pressure on the glass can be varied by using the fitted screws. Glass Dimensions (Dia.): 60mm. Please note: a sodium light source and low power microscope e.g. a vernier or travelling microscope will be required to see the rings properly.

The Polaroid stress analyser allows students to view stresses which exist in clear plastic materials. This simple apparatus consists of two crossed Polaroid filter squares (i.e. axes perpendicular to each other), 65 x 65 mm, on a plastic handle. A gap between the Polaroid squares allows clear plastic shapes (or even a clear ruler) to be placed between them, to view any stresses within the material - the stresses show as coloured areas and lines within the plastic. The analyser comes with two cut-out shapes which can be compressed to alter the stress patterns. Additional shapes are also available separately.

Tungsten metal (aka wolfram) has a very high density, 19.25 g/cm3, which is comparable to that of uranium and gold. It has a melting point of 3422 °C, which is the highest of all the non-alloyed metals. Tungsten is used in incandescent lightbulb filaments, where it emits bright light when heated to very high temperatures. It is also used in the form of tungsten carbide (compound with carbon) for wear-resistant abrasives and cutting tools. Tungsten is an effective radiation shielding material; it’s used in the nuclear industry as a non-toxic replacement for lead. Tungsten and gold have almost the same density and tungsten is used as a core material in counterfeit gold bars. It is impractical to cast tungsten because of its high melting point. Instead, powdered tungsten is pressed to shape and sintered at a temperature much lower than its melting point. Sold as a rod with dimensions: 6 mm diameter x 95 mm length, and weight 51 g.

Microwave Probe Detector

Used to demonstrate the properties of electromagnetic waves and as an aid to teaching the behaviour of visible light. The value of using microwave radiation for this purpose is two fold. Firstly, the concept that visible light is a small section of a much wider band of frequencies may be introduced. Secondly microwave radiation shares so many common properties with visible light that many experiments can be undertaken, which would otherwise be impossible due to limitations on time or equipment costs. The kit contains both the Transmitter and Receiver. The individual units are available separately and are compatible with similar 2.8cm systems from other manufacturers.

This battery operated microwave probe detector allows the student to measure, plot and investigate the microwave field intensity. The probe is slightly less sensitive than the normal receiver, and is largely nondirectional. The unit benefits from a built in amplifier with variable gain and meter displaying the relative signal strength.Output can be taken via the BNC connector either to an oscilloscope or meter. The probe detector is compatible with most 2.8cm microwave educational systems on the market. • 2.8cm microwave probe receiver •Â€Mobile, easy to use, battery operated •Â€Built in illuminated signal strength meter •Â€BNC terminated output for use with oscilloscope, meter or audio amp •Â€Gain control •Â€Non-directional

Microphone probe

Resonance Tube This apparatus is ideal for all resonance investigations in air columns particularly the Salters MUS Activity 9. The main tube takes a high power sound wave generator unit plugged in to one end. The generator is driven by a standard laboratory signal generator and as the frequency is adjusted the various resonance modes are detected by increased loudness of the note. The open pipe can be studied or a variable length closed pipe can be used by inserting the piston assembly provided. By using a higher amplitude on the generator, Kundt’s tube investigations can be undertaken. Fine cork or polystyrene dust is distributed throughout the tube and at resonance the powder gathers at the nodes. Wavelengths can be easily measured. To get a good response a closed tube is preferable, to reduce the sound levels in the laboratory while producing a measurable effect. The apparatus comes complete with two supports for the tube, sound wave generator, resonance tube, closing bung and full instructions. Dimensions (L x Dia.): 1 metre x 50mm.

The microphone probe is used for measuring sound pressure – especially in difficult accessible places. The microphone capsule is placed at the end of a 8 x 950 mm carbon fibre tube. The microphone is almost a point-size and transforms pressure variations into voltage variations. Due to its sensitivity, the microphone is well suited for experiments with our resonance tube SO150200. A cable is not included – however it must be used with a HE190105 power supply, which includes a cable. If it is to be used with the older HE110105 power supply, then a SO190109 DIN cable is required.

A bright point light source is held overhead, which shines down through the water in the tank, and casts a shadow of the waves on the bench below. The following accessories are included: Concave, convex, & rectangular Perspex plates; curved reflector; two large & one small barriers; two point dippers; plane wave dipper; hand stroboscope; banana leads; instructions. The motor requires a continuously variable 0-5 V DC power supply, and the lamp requires a 6 V 20 W supply. Alternatively, the ripple tank can be driven by the SO180324 ripple tank & LED driver.

This excellent quality Ripple Tank kit provides a comprehensive demonstration of the general properties of waves. Wave propagation phenomena are projected onto a screen. Teachers notes and experiments are provided in a superb manual. Kit comprises: • Variable vibrator • Ripple tank • Wave dampers • Electronic stroboscope projection mirror • Screen (30 x 33 cm), Wave dippers, and Accessories • Now comes complete with power supply and flashing LED strobe instead of a rotating disc PLEASE NOTE: Tripod not included (ST110120).

LED & Driver for Ripple Tanks This driver and LED lamp is designed for the classic overhead projection type ripple tank. It features a variable DC output for the motor, and another output for the LED. Electronics in the unit measure the oscillation of the unbalanced motor to calculate the frequency of the waves it generates, and can therefore modulate the LED to freeze or slow down the waves without the need of a stroboscope. The LED can be set to: • ON – where it is on constantly • FREEZE – where the frequency matches the waves • CUSTOM – the strobe frequency is controlled independently, allowing the waves to appear to move slowly or even in reverse! Compatible with ripple tanks SO58320, SO180320, and most similar ripple tanks from other suppliers. An exclusive product developed by Timstar in partnership with IPC Electronics, designed and manufactured in the UK.

Loudspeaker Signal Generator This has to be the best signal/function generator available for educational use! Developed in conjunction with physics teachers and designed specifically for education, this unit provides all the functionality you need for physics teaching. A really useful feature for those less familiar with using signal generators is that for basic use, you just operate two buttons: One for frequency and one for amplitude - that’s it! There is, of course, far more sophistication for those who require it. If you want to change waveform or to utilise the step and sweep modes, the display keeps you updated on the status of the generator. Unique frequency control: The frequency is set by a speed sensitive button. Turn slowly to set the display’s last digit, turn faster and the response accelerates - designed to work intuitively in practical experiments. Drives speakers, vibration generator etc. directly: The built-in 10 W power amplifier effortlessly drives power appliances e.g. vibration generator. The amplifier can deliver more than 1 amp for all frequencies between 0.001 Hz and 100 kHz. Step mode: In many applications you need to study a physical system at a fundamental frequency and at different multiples of that frequency. The special step feature makes this task incredibly easy. Once the fundamental frequency has been determined (e.g. of a spring connected to a vibration generator), other harmonics (or overtones) can be demonstrated by simply pressing a button, which changes the frequency to progressive multiples of the fundamental frequency. Sweep mode: The generator can sweep through a frequency range in order to discover eventual resonances. You decide the frequency range and the speed. You have the choice between a linear sweep (fixed number of Hz per unit time) and a logarithmic sweep (fixed number of octaves per unit time). Advanced Features: The generator connects to your PC through a standard USB cable and acts as a USB flash drive. Custom defined waveforms (e.g. created by means of a spreadsheet) can be saved to the generator. Sequences of settings can be programmed for automatic execution.

This 4W, 8 Ohm Mylar-cone loudspeaker comes mounted on an acrylic base, so that it can be used either vertically or horizontally. The front of the speaker has a hard protective cover with drilled holes. Dimensions (Speaker Dia.): 60 mm. Overall Dimensions (H x W x D): 120 x 90 x 40 mm.

Bell in a Jar Experiment An improved version of the classic Bell in a Jar experiment. The base is fitted with a rubber sheet which ensures a good seal between the jar and pump plate, without the need for vacuum grease. The pump plate is lightweight aluminium, mounted on a heavy tripod base, with a tube connection to the central pillar to evacuate air from the bell jar on top. A stopcock allows the chamber to be sealed, allowing the vacuum to be kept when turning off the pump. The bell jar is robust acrylic which is safe in the event of implosion, measures 25 x 14 cm, and has a flat flange to ensure a good seal with the pump plate. The bell is suspended by wires to reduce conduction of sound to the bell jar. Connection is by 4 mm sockets on the top bung. The bell can be heard getting quieter as the air is evacuated. Then, by closing the tap, turning off and disconnecting the pump, and then slowly allowing the air back in, the bell can be heard getting louder, as air is required to conduct the sound. The high-quality bell operates on 4-6 V DC or AC. Requires a suitable vacuum pump, and heavy-walled vacuum/pressure tubing.

Spillage Chemical Spill Kit

Uni-Safe Chemical Binder

This kit is suitable for small chemical spills and is often found in laboratories. Comprising of pads, socks, disposable bags and ties. Comes with instruction sheet, all contained in a clear plastic bag.

UNI-SAFE has been developed by the German Chemical Industry in close cooperation with fire brigade specialists and it is designed to effectively absorb all liquid chemicals. The composition of UNI-SAFE does not allow any dangerous reactions, even with strongly reacting and oxidizing substances such as nitric acid, oleum, bromine, sulphuric acid, or hydrogen peroxide. For example, when nitric acid is bound by UNI-SAFE there is no formation of nitrous gases when using a copper splinter. The main component of UNI-SAFE is a polymer with an extremely high absorbency rate. Therefore UNI-SAFE is able to bind liquids with a volume of up to 75 times its net weight. 2 g of UNI-SAFE can absorb 150ml of water. While UNI-SAFE physically absorbs nonaqueous substances through its capillary action, aqueous substances are bound in a chemical-physical process.

Chemical Spillage Pads These chemical absorbents are designed and manufactured to deal with all chemical spillages, including most common acids, alkalis and solvents. They should be used where any aggressive chemicals are spilt and benefit from fast action, high absorbency, coloured for visual recognition, are simple to use and are heat bonded to prevent delamination during use. Non toxic and non reactive they reduce clean-up costs and time. Once contaminated, these absorbents must, of course, be treated with the same hazard caution as the chemical they contain and should be neutralised/ disposed of accordingly. Box Weight: 3.8kg. Sorbency: 0.55 litres per pad. Pad Dimensions (L x W): 400 x 500mm. Supplied in a pack of 100.

Modified Polycaprolactone (PCL) (CoolMorph)

Super Snow

Hard, tough mouldable plastic material which melts at just 42 °C. This is a modified variant of polycaprolactone (Polymorph), which has been modified to reduce the melting point from 60 °C to 42 °C. It can be shaped by hand after only a few minutes in hot water, and can be reheated and reshaped over and over again. The lowered melting point means the soft plastic can be handled with little risk of burning hands or fingers. This also allows more time to shape the material before it solidifies. Polycaprolactone (PCL) is an industrial polymer used for applications such as hot-melt glue and laminating pouches. It is non-toxic, biodegradable and can be coloured with dry colour pigments. This low melting point variant is used for sculpting, model making, and prototyping. Supplied in a bag of 1 kg.

Make ‘snow’ in a matter of minutes with this amazing Super Snow polymer, which expands to over 100 times its size and last for weeks without rewetting. In addition, the ‘snow’ can be reused. Simply add to water and stir until expansion occurs, creating a wet looking ‘snow’. Pack includes 60 g of Super Snow, colouring tablets (to create different coloured ‘snow’) and instruction sheet.

Polyox

Hydrogel

(Polyethylene oxide) In a non-toxic, longchain polymer with a high molar mass. Because of extensive hydrogen bonding, it is soluble in water. A solution of Polyox (approximately 1% w/v) behaves as an ‘elastic liquid’ i.e. it ‘self-siphons’. If you quickly drag some of the solution from a beaker with a spatula or spoon, it will continue to move out of the beaker. You can even draw it up into a syringe even though the tip of the syringe is above the liquid level (5g is sufficient to make about 500 cubic cm of the fluid). Please note: Propan-2-ol is required for use with this item.

These completely non-toxic crystals absorbs up to 500 times its own weight in water and is the ‘secret’ ingredient used in applications ranging from babies nappies to perpetual growing plants. When exposed to water, the powder transforms into a gel which holds the water for an extended period. Supplied in a bag of 500 g.

Thermochromic Smart Cord

UV Beads

This temperature reactive extruded polythene cord (mono filament) contains a thermochromic pigment which changes colour at 31°C – from red to pale pink. Normally, when a mono filament is extruded (like a nylon fishing line) the cord is mechanically stretched to align the molecules along the length of the cord. This provides the strength, i.e., when the cord is stretched, it thins down but gets stronger. This smart cord is un-stretched and when pulled the molecules realign and the cord becomes stronger (this has to be done quite slowly). Also, when you stretch the cord, the realignment of molecules generates heat and the cord warms up and changes colour! Dimensions (Dia. x L): 1.5mm x 10 metres.

These low cost beads are extremely sensitive to natural light and change colour dramatically from white to various colours when taken outside even on an overcast day. Containing trace amounts of a photochromic pigment that responds the ultraviolet component of daylight, the beads have many different uses ranging from scientific testing of (UV) sun block materials to the creation of ‘smart’ jewellery.

UV Fluid

Photochromic Pigments

Non-toxic liquid paraffin containing a UV sensitive photochromic dye. Indoors it appears as a clear liquid but when exposed to natural light it immediately becomes coloured. This colour increases in intensity when exposed to direct sunlight. The colour change is reversible, although it takes about 60 seconds for the liquid to become clear again. Makes a fantastic demonstration of photochromic phenomena. The same dye chemistry is used in photochromic lenses, special window glass etc. Photochromic cells, for quantitative measurements, can be made, by trapping a drop of the fluid between microscope slides or petri dishes. The material can be activated by UV LEDs. Provided in a 50 mL pot.

A selection of pigments that change from pale to stronger colours in the presence of UV light. The pigments take the form of a thick cream. The active photochromic dye is contained in micron-size microcapsules dispersed in water to make up the pigment ‘cream’. It is especially sensitive to UV light which produces an almost instant colour change. The pigment then takes several minutes to decay back to its original pale colour. When mixed with a binder (e.g. acrylic base SM76260 or acrylic paint), the pigment can be permanently applied to almost any surface. The more dilute the pigment, the less dramatic the colour change; the mixing proportions are therefore a matter of trial and error. The practical applications of the pigments are almost limitless. Uses range from UV warning systems to ‘smart graphics’ in publications and packaging and garment design. Methods of application include: brush painting, block printing, stencilling, screen printing etc. Housed in 3 g syringes.

€12,94 ea

Gadolinium is an important member of the ‘rare earth’ (lanthanoids) group of elements and is used to regulate neutron activity in nuclear reactors and may be alloyed with other rare earths for applications such as magnetic recording heads. Of particular interest is that it has an exceptionally low Curie point - the threshold at which a material changes from ferromagnetic (attracted to a magnet) to paramagnetic (not attracted). The Curie point for gadolinium is approximately 20°C, which means its magnetic properties can be readily investigated at temperatures easily obtained in the classroom. Although expensive, and reactive in air when pure, gadolinium is available as embedded particles in a polythene extrusion, which also contains a thermochromic dye as a useful visual marker of the transition point. If the (normally red) cord is floated on cold water it will be attracted to a small neodymium magnet. If floated on hot water the cord loses its colour and is no longer susceptible to magnetic attraction - i.e. when the cord is red the embedded gadolinium is ferromagnetic and when colourless paramagnetic. Sold by the metre.

Silk Cocoons These cocoons are the source for all silk thread and fabrics and reveal something of the amazing story of silk. Each cocoon contains up to 0.5 miles of silk woven into a hard shell by the silk worm. To extract the silk, each cocoon is placed in hot water to soften the natural binding agent. A loose end of thread is then wound onto a reeling drum along with the threads of several other cocoons to form a thicker fibre. As the cocoons are exhausted, others are added to the reeling thread. This is a labourintensive operation conducted on a gigantic scale considering the world tonnage of silk now consumed. The material itself has one of the highest strength to weight ratios known and past uses reflect this - e.g., it has been employed for armour, parachutes and (in single strands) for cross wires in scientific instruments. The raw cocoons - which have the ‘feel’ of small hard eggshells - have recently found new and unusual uses in product design including diffusers for LED lighting. To unwind the silk, simply place the cocoon in very hot water for about 1 minute and then pick up a loose end of the wrapping and lift it vertically. As you lift, the silk will come away in a continuous thread - for up to 0.5 mile! Cocoon Dimensions (L): 24mm. Supplied in a pack of 10.

Make a circle, join hands, use the Cosmic Ball to complete an electric circuit and watch as it lights up, pulses brightly and emits a sound when the circuit is completed.

This toy has a serious scientific purpose because it provides a stunning demonstration of vortex formation and transmission. When the toy is ‘fired’ a doughnut shaped ring of air (the vortex) is generated and moves outwards at high speed. It has sufficient energy to create a noticeable impact at some distance - hence the toy interest. Ideal as a design project to attempt to recreate the same effect using cardboard boxes, etc.

Rulers & Geometry Best Fit Line Ruler This is a revolutionary new stationery instrument. It has all the uses of a traditional ruler, but can also help you to draw the best fit line on a scatter graph much more accurately and easily than you can with a traditional ruler. With the grid pattern, you can be really sure that you have the points equally spaced on either side of your best fit line, and as close to it as possible all the way along. Plus it has centimetre and millimetre markings so you still get all the functions of an ordinary ruler! Use the BFLR to draw your graph and plot the points as normal, then use the grid to locate the best position for the best fit line, as indicated by the central slot in the middle of the ruler. Slide your pencil along this central slot to produce a crisp and accurate best fit line. RU105900 RU105901 RU170100

Elements Poster, Extra Large This beautiful double-sided periodic table poster uses images from Theodore Gray’s library of thousands of element samples; many collected or re-photographed especially for these posters. (A few highly unstable elements show a picture of the person or place after which the element is named, or a mineral that contains trace amounts of the element.) The posters are laminated on both sides and printed on the highest quality paper, using special processes which result in razorsharp images. Poster dimensions: 68 x 134cm (27” x 53”).

Elements Poster, 3D Lenticular This amazing 3D version of Theodore Gray’s original Periodic Table of the Elements poster is printed using lenticular technology, which uses linear lens elements laminated over a specially processed image to display different views to each eye, creating a convincing stereo 3D effect so that the element samples appear to stand out from the surface of the paper. On the back of the poster is a listing for each element that includes: name, atomic number, atomic weight, melting point, boiling point in ºC and density in g/ml. Poster dimensions: 59 x 28cm (22” x 11”).
