CHEMICALS

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

UNDERSTANDING THE CLP LABELS

INFO

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.

Product Name

Acetaldehyde LR (Ethanal)

Alternative Product Name Hazard Statements/ Precaution Statements: see pages 6-7 for the full list of definitions.

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.

Flash Point Signal Word

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 Support Team on: +44 (0) 1743 812 201 or email: export@timstar.co.uk with all your enquiries.

INFO

Relative density or specific gravity is the ratio of the density of a substance to the density of a given reference material. The standard reference material is water @ 4 °C. The term “relative density” is often preferred in scientific usage. It is defined as a ratio of density of particular substance with that of water.

HOW DO I WORK OUT THE MOLARITY OF A CONCENTRATED ACID FROM THE PERCENTAGE ASSAY?

INFO

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. Molarity = density (g/l) x assay(%) ÷ mol. wt. 100

LOOKING FOR SOMETHING? To complement our extensive range of chemicals, Timstar offers a comprehensive range of glassware, including beakers, conical flasks, burettes, and test tubes. Timstar also offers a range of glass reagent bottles which are ideal for long term storage of concentrated nitric acid. The full range is available online: timstar.co/labware

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

Centrifuges Clifton Tara Centrifuge

The Targa Centrifuge (NE010G) 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 wipe-clean. 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 lock • Lid drop protection • Auto door release

ISG Clinical 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 3004500 rpm and a maximum rotor capability of 8 x 15 mL tubes the clinical centrifuge allows precise control of time and speed ensuring an efficient separation process. The centrifuge also has 15 mL 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 56 dB 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]: 2490 x g, increment: 100 x g • Speed Accuracy [rpm]: ±20 • Rotor Capacity: 12x10 mL/7 mL/5 mL; 8x15 mL • Run Time: 30 sec to 99 min - HOLD (Continuous operation) • Driving Motor: Brushless DC motor • Safety Devices: Autolock lid when centrifuge is spinning • Quiet operation <56 dB • User friendly Large LCD screen • Education price for Medical/University specification • Quick spin Mode • CE marked • Spins to 4500 rpm • Detailed instruction manual included

All Clifton water baths feature a powder painted body which provides a durable finish and protection against corrosion and incorporates “active anti-bacterial technology”. This paint finish actively inhibits bacterial growth, improving hygiene requirements and is effective against major strains of bacterium including E-coli and S-aureus, resistant strain. Within its formulation the active anti-bacterial ingredient is bound into the coating during application and curing, which ensures it will remain effective over time.

Irwin School Water Bath

A water bath specifically designed for Science Departments, utilising a deep Gratnells tray, turning it into a water bath. The control head slots on and off the end of the bath for easy storage in the tray, which can be stored in any Gratnells rack or trolley. The control head is multifunctional, allowing control with a precision of 1 °C and has a number of failsafe functions including memorising the last setting should it be accidentally switched off. It can be locked to prevent students from changing the settings and has a wandering thermostat which can be placed in vessels in the bath to maximise control of the temperature for the items under investigation or in preparation.

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.

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.

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 fitted 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. HEAD

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

Illumination can be provided in several ways. • Mirror – a plano-concave mirror situated on the base which collects light from 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 for 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.

N.A NUMERICAL APERTURE NOSE PIECE

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. RMS

Royal Microscopical Society. RETRACTABLE OBJECTIVE

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

Frederiksen 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. Waveforms 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 Distortion (sine) 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.

ALSO BOUGHT...

INFO

TST (Temperature, Steam and Time) strips 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 2 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.

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:

Deionised Water

• 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.

• Life expectancy of deionising cartridges depends on water hardness, 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.

t: +44 (0) 1743 812 201

£263.25 pk

INFO

Distilled Water

• 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.

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

• Removes minerals/salts from water using a semi-permeable membrane under high water pressure.

• 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.

APPLIANCES

Visualising

VISUALISERS Visualisers may not be new to the classroom, but recent events have seen a resurgence in their use. If used effectively, they can prove to be a very helpful tool in helping students maximise their learning and improve engagement. Some key benefits of using visualisers in schools include:

• • • • •

Supports peer and self-assessment by giving on the spot feedback Frees up teachers’ time, improving productivity Improves comprehension and reduces marking Promotes inclusion in the classroom Share best practice and resources across the school

Perfect for practicals! Due to the incredibly high resolution of the Joyusing classroom visualisers, you’re able to zoom in really closely. If you are using picture sources or stimulus, or even doing an activity like dissecting, reacting chemicals or electronic circuitry, having the capability to highlight minute details to students opens up a whole extra world of discovery. Whereas previously, you may have used static images or huddled them around a table, using your visualiser to zoom in on details and project them means that you can pick out details that were previously difficult to access.

Biological Models

BIOLOGY Beta Globin Folding Kit

Structual Models Amino Acid Starter 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 handson 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 handouts and interactive Jmol visualisation (an open-source Java viewer for chemical structures in 3D).

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 side-chains, 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 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 sugarphosphate 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 sugarphosphates and 48 orange phosphates.

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. BT190000

Food Calorimeter

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.

Dimensions Body: (H) 215 mm, (H) including stirrer 275 mm, (D) 100 mm. Dimensions Base: (H) 110 mm, (L) Retort Clamp 70 mm, (L) Total 170 mm, (D) 100 mm.

BIOLOGY

Biology Equipment Compact Contraception Kit

Genetics Genetic Taste Test Strips

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. A

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. 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. 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.

If using the bottled gases to fill rubber or latex balloons, due to the surprisingly large volume of a balloon (e.g. a 9 ”/23 cm spherical balloon would have a volume of approx. 6.3 litres) and also due 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.

Atomic Models 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.

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 27 white ball atoms arranged in a 3 x 3 x 3 lattice, connected by 54 springs. Dimensions: 185 x 185 x 185 mm.

Study the unique molecular structure of carbon nanotubes. Fullerene molecules are all visually interesting and can be well represented by molecular models. Their unique molecular structure results in numerous potential exciting applications in current day nanoscience which can engage pupils and help to create a link between chemistry and the ‘real world’. This 530 mm model uses atoms from the Minit system which can be arranged to show the chair, zigzag or chiral structures of the tube and the associated properties. Particular areas to study include: • The similarities in structure of carbon nanotubes and the layers in graphite. • How curvature is achieved in the molecular shape of the ends of nanotubes due to the difference in bonding angles. • Different symmetries of carbon rings in the carbon nanotube - the chair, zigzag and chiral structures - and how these differences affect properties such as strength and conductivity and hence potential applications. Kit contains 260 atoms. Please note this kit version requires assembly.

INFO

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.

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).

£67.43 kit £94.43 kit £202.50 kit

INFO

The following mains voltages and frequencies apply: UK 230 V 50 Hz Europe 230 V 50 Hz USA 120 V 60 Hz Previously, Europe operated on 220 V and the UK on 240 V. 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. 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).

Locktronics

Locktronics is a range of products that simplifies the process of learning and teaching electricity and electronics. The core range consists of more than 200 electronic components mounted on rugged plastic carriers which are printed with the corresponding circuit symbol. Students use these carriers, in conjunction with a baseboard with interconnecting metal pillars, to build up a working circuit. They then use the software and curriculum provided to carry out experiments in electricity and electronics. The key benefit of Locktronics is that as students construct the working circuit they can also see the corresponding circuit diagram. This helps students link theory to practice and simplifies the process of learning electricity and electronics. Locktronics is used in more than 10,000 schools worldwide. Teachers and students like to use Locktronics for a number of reasons: • Students can see the circuit diagram and the real circuit • Circuits are fast to build and easy to work with • Support materials guide students step-by-step • Locktronics is reliable and works year after year • Curriculum and worksheets are provided • Components mounted on rugged plastic carriers • Simple, effective, strong baseboards • Component legend bonded to plastic carriers • Can be used in many subject areas, at many levels • Vast range of components • Ideal for demonstrations, practicals and projects • Components and curriculum now updated • 12 month guarantee on all items • Technical telephone support on all products

Spring clips riveted on for strength.

Components identifiable under carrier

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

INFO

• 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, (yellowwhite) 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). 1800K

Resistance

NEED TO MEASURE RESISTANCE? There are several methods to investigate resistance. A wire potentiometer can be used to find the resistance of the wire at different lengths. A Wheatstone bridge can also be used for this investigation, and in addition, it can be used to find the resistance of unknown electrical resistance. Wheatstone bridges provide very accurate measurements. Required practicals for investigating resistance include:

Investigating how the resistance of a wire varies with its length

Investigating resistance in series and parallel circuits

Resistance Wire Board

This apparatus provides the basis for student investigations into resistance. Four wires, 500mm long mounted on an acrylic base and connected via 4mm sockets. The wires are all Nichrome with diameters of 1.0, 0.8, 0.63 and 0.4mm giving resistances in the range 0.4 to 4 ohms. A graduated mm scale is included allowing resistance V length and resistance V diameter investigations to be easily covered. Dimensions (L): 500mm.

Wheatstone Bridge

PLEASE NOTE: The powder INFO coat used for the acid cabinets is splash resistant not acid proof. There is not an acid proof powder coat on the market. If spills are not cleaned up or bottles are left open the fumes alone with some acids will take the paint finish off and start to corrode some components in time. If in any doubt, then we would suggest that some form of extraction is fitted to the cabinet in order to remove the vapours.

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 it can be a valuable tool within the education sector. • Standard Filtration to 5 microns (optional HEPA filters available) • 0.5 m/s air velocity at filter • High Efficiency Carbon Filtration • Low Power Consumption • Single Phase Power Supply • No installation costs • Virtually maintenance free • Easy filter change • Quiet unobtrusive fans • Lifetime Warranty • Recirculatory action • Three stage particulate filtration • High Efficiency Activated Carbon Gas Filters • Powder Coated Mild Steel Hood • Clear High Visibility PETG capture shield • Brushless Centrifugal Blower (larger models have 2 blowers) • Optional 0.3 m HEPA filtration • 230 V AC 50 Hz • Dimensions (W x D x H): 680 x 660 x 610 mm • This unit is UK designed and manufactured FU101840

The brilliance of these products is that Quickfit only makes 20 joints from the mould before it is recalibrated, so you can buy different pieces years apart and they will still fit together.

Quickfit joints are made with a 2-way grinding process making the system fully interchangeable. The rounded profile adds mechanical strength, and is more resistant to chipping, compared to other brands which have a square profile. There is no need to use grease in the joints and you can also buy clips for extra security. All conical joints have an accurately ground cone & socket with 1:10 taper and the ground finish of a Quickfit joint ensures:

• No joint seizure • No fluid leakage • Joint is gas & vacuum tight Joint sizes can be found printed on your Quickfit glassware and are specified as two numbers e.g. 24/29. This means that sockets or cones of this size have a diameter of 24 mm at the widest end and have a 29 mm length of engagement. Ideally, the cone and socket should both be the same size. A cone or joint, size 19/26 will fit into a socket size 19/26. However, if you have a mix of sizes that won’t fit together Timstar offers a range of expansion or reduction adapters enabling you to use your glassware once more.

Quickfit Cone/Screw Thread Adapters These adapters are ideal to connect thermometers and inlet tubes to your Quickfit assemblies. They are supplied complete with a plastic cap, silicone rubber ring and PTFE washer.

BEST SELLER

Beakers

TIMSTAR PROVIDES A RANGE OF DIFFERENT TYPES OF GLASSWARE DEPENDING ON YOUR REQUIREMENTS AND BUDGET. There are essentially 3 types of laboratory glassware: Soda lime glass is suitable for general laboratory use and can withstand moderate warming (e.g. in a water bath) but NOT direct heat. It is an economical choice for situations where direct heat is not required.

Neutral borosilicate glass can withstand moderate temperature changes. Neutral borosilicate glass has a good chemical resistance and is a cheaper alternative to borosilicate 3.3 glass, when only gentle heating is required.

Burettes

Class A and Class B refer to the accuracy of our range of burettes. Class A burettes are used when the accuracy of the experiment is very important, as they have an accuracy of up to 0.1 per cent compared to 0.2 per cent in Class B burettes. Class A is more preferred than Class B when volumetric determinations are required, so they are ideal for analytical applications. Our Class A glass burettes offer the best quality and accuracy and are calibrated to half the tolerance of Class B – and each has a unique serial number for traceability. Constructed from borosilicate glass, Timstar’s range of Class A burettes are made from precision bore glass for improved accuracy along the entire scale length. Class B burettes are ideal for general purpose work where a lower level of accuracy is required. To complete the range, Timstar offers a number of acrylic burettes as a useful alternative to glass. Acrylic is more robust than glass and is suitable for most diluted aqueous solutions but NOT alcohols or organic solvents. The choice of which burette, is down to personal preference, practicality, accuracy, or price. Burettes can also be classified by the type of graduation used, depending on the colour of the solution being titrated: • Blue – good for general purpose use • White – useful for dark coloured solutions • Black or amber – useful for light-coloured or clear solutions

Burettes

LABWARE

The stopcock valve is used to control the flow of liquid from the burette in either a steady stream or drop-by-drop:

• • • • •

Pinch clip – an older and simpler design used mainly in education. Glass key – a traditional choice due to smooth action, greater control and longer life than PTFE key stopcocks. Usually require light lubrication with silicone grease. PTFE key – most frequently used, lower maintenance option. They do not require lubrication and are less likely to jam than glass alternatives. Modular PTFE – made entirely of PTFE are particularly suitable for schools as they are more durable and all parts are replaceable Rotaflo – has a screw in/out PTFE key which allows for fine drop control.

Burners

LABWARE Premium Bunsen Burner Range

PREMIUM BUNSEN BURNERS Designed to last 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: 80 mm.

Natural Gas (N.G) 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. The temperatures achieved depend on the mains gas pressure and chemical composition of the gas. L.P.G Burners These are designed to be used with propane (at a gas pressure of 35 mb) or butane (at a gas pressure of 28 mb). The appropriate pressure reduction valve must be fitted to gas cylinders or tanks. Typical flame temperatures with air inlet fully open are in the range 850 to 950 ˚C.

Glassware Rinsing 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 600 mm 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.

Labware Sets Organic Chemistry Set (Multi-Joint)

Jointed Glassware Sets Microscale 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 QU130500

INFO

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

The medium and larger rubber bungs (stoppers) with holes have approximately 5 mm diameter holes (small sizes have approx. 3 mm diameter holes). The best size glass tubing to fit into these is 6 mm 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 5 mm bore (N5) fits nicely onto 6 mm OD glass tubing, for connection purposes.

Pen Type Infrared Thermometer Object 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 The spot size is a ratio of distance from IR distance from IR thermometer to thermometer to object being measured. object being measured. Spotsize size Spot IR IRThermometer 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.

An explanation of why laboratory thermometers can appear inaccurate when measuring water boiling.*

INFO

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.

Petri Dishes

Plastic Petri Dishes

PETRI DISHES Non-vented Petri dishes have a very small gap between the lid and the dish, which discourages evaporation from occurring. This type of dish is most suitable for anaerobic and long-term work. Vented Petri dishes have a small lip on the top edge of the dish which allows good air flow. This is ideal to encourage evaporation. 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.

INFO TEST TUBE TYPES ‘IGNITION TUBES’

These usually refer to small borosilicate glass tubes used for intensive heating of samples and are often considered ‘disposable’ due to the fact that such heating will deform the glass or make it very difficult to clean. Typical size: 75 x 10 mm (external diameter)

‘TEST TUBES’

Various glass types. Typical size: 125 x 16 mm (external diameter).

‘BOILING TUBES’

Usually neutral borosilicate or borosilicate 3.3 glass. Typical size: 150 x 24 mm (external diameter).

Test Tubes

TEST TUBE GLASS TYPES An essential requirement for delivering practicals in schools, Timstar’s comprehensive glassware range has something to suit every requirement and budget. The range includes three types of laboratory glassware: Soda lime glass - suitable for general laboratory use and can withstand moderate warming (e.g. in a water bath) but NOT direct heat. An economical choice for situations where direct heat is not required. Neutral borosilicate glass - can withstand moderate temperature changes. Has a good chemical resistance and is an economical alternative to borosilicate 3.3 glass, when only gentle heating is required. Borosilicate 3.3 glass - can be used where direct heating is required due to its high thermal resistance. It also has excellent 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. Timstar’s range of test tubes is available with a range of wall thicknesses and with or without rims. Heavy wall thickness provides additional mechanical strength, improving user safety and extending the product lifetime. Rimless test tubes are ideal for microbiology and culture work.

Atomic Demonstrations & Simulation “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.

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. Please note that these badges are not functional, and are supplied without film. They are for demonstration purposes only. 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.

Chain Reaction Apparatus

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 (RA170205).

Protactinium Generator

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: 70 s • Experiment Time: 5 to 10 minutes • Radiation Type: Beta Decay of Pa234 • Maximum Product Lifetime: 8 Years • Active Ingredient: Uranyl Nitrate

PHYSICS IPC Spark Discharge Apparatus

Radiation Frederiksen Spark Detector

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. It comes complete with sliding holder for an alpha radiation source, an accurate scale to measure the effects of distance between the source and the grid and is built in a vacuum formed black plastic case. All of the electrical connections from an EHT power supply are through 4mm insulated sockets. Connections to a Timer Scaler and Frequency Meter are via a BNC to BNC cable. Requires a 5kV EHT power supply and alpha radiation source. Weight: 400g. Dimensions: (L x W x H) 310 x 77 x 85mm.

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 electronoptical 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.

The electron beams are perpendicular to one another and a common deflector plate is provided for both guns. The electron beam source is an oxide cathode heated indirectly via a heating coil. The electron paths show up as a fine, slightly greenish beam due to impact excitation of the helium atoms. Requires a 300 V or 500 V DC power supply. • Filament voltage: max. 7.5 V AC/DC • Anode voltage: max. 100 V DC • Anode current: max. 30 mA • Deflector voltage: max. 50 V DC • Glass bulb: 130 mm dia. approx. • Total length: 260 mm approx.

Perrin Tube

For demonstrating the evidence of the particular nature of cathode rays, establishment of negative sign of charge, the “electron” as an atomic particle, concept of a “time-base”, operation of a cathode ray oscilloscope, simple Lissajous’ figures. 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. RA130500

Fine Beam Tube (Neon-Filled) with Connector Base

Helmholtz Coils for Use with Fine Beam Tube

RA130505

RA130510

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, welldefined, 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

The Pair of Helmholtz coils is used for generating a homogeneous magnetic field and for the determination of the specific charge of the electron e/m in conjunction with the dual-beam tube. The coils can be switched in parallel or in series. A spring clip on the top crossbar is used to mount the Hall sensor during measurements of the magnetic field. The maximum field strength generated by the coils (~ 4 mT) is approximately 750 times weaker than that produced by an MRI machine (~3 T), which are known to be safe for use by people with medical implants such as pacemakers.

An affordable Stirling engine which works at very low temperature differences. A cup of warm water (must be at least 60 °C) can make the motor run, which means that water heated by sunlight can become hot enough to drive this motor. Like other Stirling engines, this type works by converting temperature differences into mechanical energy as warm air expands and cold air contracts. This is utilized in a closed system where the same air is pumped back and forth between a cold and a hot engine part. Illustrates perfectly how Stirling engines operate and can be used with many different heat sources. Weight: 330 g. Dimensions (H x W x D): 144 x 90 x 90 mm.

Quick and easy to set up and use, this demonstration rarely fails to impress. 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.

Joulemeters SEP 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 mini-datalogger 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)

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.

Type Single Class set of 12 in Gratnells Tray

£40.43 ea £398.25 set

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).

INFO

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.

All Matter FDt = -mDv

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.

INFO

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.

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.

Frederiksen ‘g’ by Freefall Apparatus Kit

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).

Monkey & Hunter

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.

Frederiksen Speedgate

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 push buttons, 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.

Relay Demonstration

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

Electric Bell Demonstration

This current balance apparatus (B.I.L 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 B.I.L 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.

All the components of an electric bell are mounted on a large panel. All wiring is visible and parts are large in size. Operates on 3-4 volts DC.

Gauss Guns Magnetic Accelerator Kit (Gauss Gun)

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.

This apparatus offers a clear and easy way to observe magnetic fields generated by a constant electrical current. Iron filings can be scattered on the clear surface which passes through the coil and when a current then flows around the coil, the magnetic lines of a force will be shown by the alignment of the filings. The apparatus can also be used in conjunction with a magnetic field sensor and/or datalogger. Requires a high current laboratory power supply (8-10A) for best effect. Weight: 1.2kg.

Magnetic Fields 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.

A pair of preformed coils, each with 400 turns of copper wire, wound onto a former of approx. 150 mm diameter. Each coil is mounted on a support rod, which fits onto the sliders of the track system supplied. This enables the distance between the coils to be varied whilst maintaining alignment along a common axis, for measurements and study of magnetic fields. Electrical connection is via 4 mm sockets. Please note: the current should not exceed 1A, to prevent overheating or damage. Direction of current is marked on each coil. • 150 mm diameter • 400 turns • Max. current 1A

Using a high temperature superconductor (HTSC), this kit demonstrates an intriguing magnetic property of superconductors, known as the Meissner effect. 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

Magnetism Neodymium Magnets

UNSURE WHICH TYPE OF MAGNET TO CHOOSE?

•

Ceramic or ferrite – these magnets are the most popular type and offer a low-cost, standard level of magnetic performance with good resistance to demagnetization.

•

Magnadur – these are ceramic magnets which retain their magnetism well and are often used in DC motors.

•

Alnico & Alcomax – these are alloy magnets which have a high resistance to demagnetization making them ideal for use as strong permanent magnets.

•

Neodymium – these are rare earth magnets which are the most powerful of all the permanent magnets and are often known as “Super Magnets”.

Powerful disc magnets with the poles on the flat surfaces. Please Note: These magnets are brittle and fragments can fly off if magnets are allowed to come together rapidly, potentially causing harm or eye damage. Careful handling is also required to prevent skin from becoming trapped between two magnets.

Permanent magnets will retain their magnetic strength for several years but impacts, drops and misuse will weaken them. Keeping the small pieces of iron “keepers” supplied with them over their poles will help retain their magnetic properties.

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 highquality 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.

Kinetic Theory Model

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 stationary 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.

PHYSICS Colour Mixing Apparatus

Colour Mixing Colour Mixing Box

This unit contains three coloured light sources (red, green and blue) projected onto a screen in overlapping circles. The unit is self-contained, 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.

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.

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). Red + Green = Yellow

Blue + Green = Cyan

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.

Pinhole Cameras

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

Pinhole Cameras Kit

This pinhole camera class kit contains enough components to make 10 pinhole cameras. The kit includes 10 square section black plastic tubes, 200 x 60 x 60 mm each, pre-cut black card and translucent paper for mounting on either end of the tubes. A small pin-hole in the black card will then project an image onto the translucent paper at the opposite end of the tube. Requires a bright light source (e.g. OP110155 or antique lamp) or desk lamp with suitable object to project an image.

Planck's Constant Apparatus

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).

The ancestor of all cameras, this hand-held camera obscura projects an image onto a screen inside the box. The wooden camera is supplied in kit form and has an authentic look and feel when assembled. Supplied as a pack of 10 kits. OP160012

Frederiksen Planck’s Constant Apparatus

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.

Vibrations & Waves Timstar Rubens' Tube

Resonance & Rubens' Tubes 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.

Designed by Timstar in response to customer enquiries, the Rubens' Tube provides memorable demonstration of standing waves. The Rubens' Tube consists of an 10 cm diameter aluminium tube with a row of small holes drilled along the top, and a 15 W loudspeaker mounted at one end, and is supplied with instructions. Natural gas or LPG can be used, with a length of burner tubing to connect it to the supply. The speaker can be driven directly using a signal generator with power output, but a Rubens' Tube Driver (SO180900) is recommended for best effect. See our website for more information and video links to Rubens' Tubes in action. Designed and manufactured in the UK.

IPC 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.

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.

SAFETY & PROTECTION

Hand Protection

Make sure to purchase the right type of glove according to regulations and to use gloves appropriately. The following advice is intended to help you choose suitable gloves for protection against a variety of risks. For chemical protection CLEAPSS advises the use of re-usable gloves (usually EN 374-1/Type A) for instances where chemical exposure could present a high level of risk of causing damage to skin. Disposable gloves would be used in cases where chemical exposure would present a lower level of risk. Schools usually need a few dozen pairs of re-usable “/Type A” gloves while also keeping several boxes of “/Type B” available. Each letter on this standard indicates a chemical to which the product has been tested and approved to.

TIMSTAR’S GUIDE TO RELEVANT REGULATIONS: Chemical & Biological • EN 374-1/ EN ISO 374-1:2016/Type A • Type A (ex. ABCDEF) The product can withstand 6 chemicals* for at least 30 minutes. • Type B (ex.

Fun Experiments Circuit Maker/Breaker

This fun resource can be used to demonstrate open and closed circuits. Completely safe to use, simply touch both the contacts on each end of the stick to form a complete circuit. When a circuit is formed the Circuit Maker/Breaker will emit a loud beep and the lights on the front will glow up. As soon as one of the contacts isn’t touched, the circuit will be broken and the Circuit Maker/Breaker will stop working. Bring some WOW to your lesson by adding more and more people to the circuit! Get the children to form a circle linking hands so that the circuit maker breaker will light up and beep, but when the link is broken then the stick stops working. How many children can you get to complete your circuit? Add a further challenge by allowing the children to find objects to put in the link that will break or continue the circuit for the stick to work! Or use the Circuit Maker/Breaker as a tester of insulators or conductors by covering the ends of the stick with different materials and testing whether a circuit can still be created. Based on teacher feedback, we have specifically designed the Circuit Maker/Breaker to be large in size so that it can be seen by all of the class. Measuring 15 x 5 cm in size and made from durable ABS plastic the Circuit Maker/Breaker is powered by 2 x AAA batteries with a battery life of approx 1 year in standby.

Smart Metals & Sand Field’s Metal

This remarkable alloy melts at just 61°C but, unlike the most familiar low melting point alloys, does not contain lead or cadmium. It is a relatively hard and extremely tough alloy that has a wide variety of scientific and manufacturing applications. It is used for example to fill small tubes for bending without crushing, casting for models and jewellery, and for making precision moulds. Although relatively expensive because it contains the rare element indium, Field’s metal makes a fantastic demonstration of how several constituents, each with a much higher melting point, can be combined to produce a fusible alloy. Note: indium has risen in price recently because of its use in LCD TV screens. It BEST ‘wets’ and adheres to many surfaces hence the propensity of Field’s metal to SELLER adhere to plastics.

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 nontoxic, biodegradable and can be coloured with dry colour pigments. This low melting point variant is used for sculpting, model making, and prototyping.

RICHTER SCALE

The Richter scale, devised by Charles Richter in 1935, is a quantitative measure of the magnitude of an earthquake.

INFO

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. 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.

SPECIALIST SCIENCES Calcium chloride anhydrous - granular LR

Field Studies Timstar Choice Chamber

Robustly made from injection moulded acrylic, with 4 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. The choice chambers come without the mesh material, which is available separately. Dimensions (Diameter x Depth): 200 x 35 mm.

Blood Analysis Forensics Using Simulated Blood Kit

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 Kit

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 Teacher’s 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.
