Frederiksen Signal Generator

A high quality, simple-to-use student signal generator with a range of applications. Three controls: waveform, frequency, and amplitude, control the output. The waveform and frequency are displayed on the built-in LCD. Output is via a pair of 4 mm sockets. It can be used for most experiments involving sound or vibrations that would be carried out in school.

• Overload protection • LCD screen • Power supply included

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. The amplifier can deliver more than 1 amp for all frequencies between 0.001 Hz and 100 kHz. Step mode: In many applications you need to study a physical system at a fundamental frequency and at different multiples of that frequency. The special step feature makes this task incredibly easy.

Once the fundamental frequency has been determined (e.g. of a spring connected to a vibration generator), other harmonics (or overtones) can be demonstrated by simply pressing a button, which changes the frequency to progressive multiples of the fundamental frequency.

Sweep mode: The generator can sweep through a frequency range in order to discover eventual resonances. You decide the frequency range and the speed. You have the choice between a linear sweep (fixed number of Hz per unit time) and a logarithmic sweep (fixed number of octaves per unit time).

Advanced Features: The generator connects to your PC through a standard USB cable and acts as a USB flash drive.

GLASSWARE AND PYREX

WE RECOMMEND ...

Timstar stocks three types of glassware, used in education:

Pyrex is a premium glassware range which has been manufactured in the UK since 1923. The brand is synonymous with quality and longevity.

Soda Lime glass is suitable for general laboratory use and can withstand moderate warming (e.g. in a water bath) but NOT direct heat. Soda Lime glassware is an economical choice for situations where direct heat is not required.

Robust rim profile

• Ensures less chipping • Provides mechanical strength Uniform wall thickness

Borosilicate 3.3 glass can be used where direct heating is required due to its high thermal resistance. It also has excellent chemical resistance. Pyrex is an excellent and trusted brand of this type of glassware:

• Reduces risk of breakage Graduations printed

• Long lasting even after dishwashing

Neutral Borosilicate - the glass can withstand moderate temperature changes. Neutral borosilicate glass has good chemical resistance and is a cheaper alternative to if borosilicate 3.3 glass when only gentle heating is required you have budgetary limitations.

Flat, even base

• Eliminates hot spots reducing breakages

• Maximises surface contact and thermal transfer

We recommend… Pyrex Manufactured since 1923 this well established and trusted brand has been used, tried, and tested by schools all over the globe – a brand recognised for its quality and longevity. Benefits include:

⋅Full compliance with ISO 3819 and DIN 12331 ⋅Manufactured from Pyrex® borosilicate 3.3 glass ⋅Fantastic thermal performance ⋅Highest resistance of chemical attack ⋅White graduations of marking the spot

Microscale Kit

The Quickfit® Microscale Chemistry Kit was designed to perform organic chemistry experiments, but on a much smaller scale.

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

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

SEP Joulemeter, Low Voltage

SATZ Bench Meters Supplied in a strong high grade ABS case, with a large bold LCD and 4mm colour coded sockets.

Powered by 1 x 9V PP3 Battery (supplied).

Dimensions (L x W x H): 95 x 90 x 75mm.

TECHNICIAN’S CHOICE

A USB low voltage Joulemeter which includes datalogging and can be used with or without a computer. 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).

The meter keeps a log at the chosen sample rate when the total energy transferred is being measured; the data can then be loaded on to a PC using free minidatalogger software.

Energy Transfer Unit

Thermal Conductivity Bars

Developed for the Science Enhancement Programme (SEP) this single unit demonstrates a range of different energy transfers; for example, how energy is transferred electrically from a handturned dynamo to a motor. The unit is accompanied by a booklet that discusses some of the key teaching and learning issues that surround the energy concept, and provides a series of activities that illustrate how the unit can be used to develop simple and coherent ways of talking about energy.

These are safe, clean (no wax) and easy to use.

The durable liquid crystal strips embedded in the bars show how a red zone of 40°C moves up the bars. The colours give a dramatic view of conduction and the marked difference in temperature gradients in the bars is also visible.

By immersing the heated bars into cold water shows how conductivity applies to heat leaving the metal. The tops of the bars are designed to be touched with a finger tip to reinforce the colour observations. Please note that the glass beaker, retort stand and clamp are not supplied.

Ripple Tank Kit

An overhead projector type ripple tank for demonstration of wave phenomena (reflection, refraction, diffraction, interference). Two arms hold an electric motor, onto which either two-point, or a planewave dipper can be attached. An overhead light source, illuminates the tank and casts a shadow of the waves onto the bench below.

Accessories include: concave/ convex/rectangular perspex plates; curved reflector; three barriers; two-point dippers; hand stroboscope; banana leads. The motor requires a continuously variable 0-5 V DC power supply, and the lamp requires a 12 V AC supply. Alternatively, the ripple tank can be driven by the SO180324 ripple tank & LED driver.

Ripple Tank Kit, Frederiksen

Provides a comprehensive demonstration of the general properties of waves. Wave propagation phenomena are projected onto a screen.

Teachers notes and experiments are provided in a superb manual.

Kit comprises: • Variable vibrator • Ripple tank • Wave dampers • Electronic stroboscope projection mirror • Screen (30 x 33 cm), Wave dippers, and Accessories • Now comes complete with power supply and flashing LED strobe instead of a rotating disc PLEASE NOTE: Tripod not included (ST110120).

This apparatus comprises a reservoir with a bourdon gauge, connected to a vertical glass tube. The reservoir has a needle valve to control pressure, and a high-quality tyre-type valve for attaching the supplied pump. Air does not escape when the pressure is increased, until the needle valve is opened. The pressure is displayed on a bourdon gauge, which has a transparent back, allowing students to see the internal workings. Pressures of up to 3.5x atmospheric pressure can be measured, which provides a good range of measurements. The tube 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.
