These plastic rules have black marking on white plastic for easy reading,. One edge is divided into \ninches and tenths the other in centimetres and millimetres. \nDimensions 25mm wide and 5mm thick.
These plastic rules have black marking on white plastic for easy reading. Both sides in centimetres. \nDimensions 25mm wide and 5mm thick.
Robust colour co-ordinated sand timers giving accurate interval times for individual pupil use. Ideal for use in both Science and Maths lessons. Size: 90mm x 25mm.
These plastic rules have black marking on white plastic for easy reading. Both sides in centimetres. Vertical reading \nDimensions 25mm wide and 5mm thick.
Horizontal reading rulers made of clear transparent plastic. One edge graduated in millimetres and figured every centimetre, other edge graduated 1/10th of inch and figured every inch.
These scales are dual calibrated. Use grams for a mass activity and newtons for a force activity.

A copper nickel alloy of low temperature co-efficient suitable for resistance coils etc. Eureka/Constantan Wire, Bare, 0.40, 28swg 125gm
A nickel-chromium iron alloy especially suitable for high temperature applications such as elements, rheostats etc. Nichrome Wire, bare, 0.71, 22swg 125gm
This simple, miniature, voltmeter is an ideal way to make Voltage measurements in electrical circuits. Specification: Maximum Voltage 20V dc Resolution 10 mV Accuracy ±2%
Connect the positive lead to the + terminal. Takes plugs or use crocodile clips.It features the Buzzer symbol on top.
Energizer alkaline batteries are Industrial-grade batteries to power heavily used, high current drain devices. These alkaline batteries have a consistent capacity, designed for industrial and commercial markets. Alkaline batteries last up to 7 tim
Moving Coil DC Voltmeter (EDM-80). Scale Length approx. 60 mm with anti-parallax mirror scale, dial size 72 x 72 mm with color coded terminals. Overall size 90 x 110 x 125 mm approx. Accuracy : ±2%

This Relay Demonstration Unit allows the investigation and study of how a relay functions in a clear and practical manner. A useful property of this \nDemonstration Relay Unit is that the circuit powering the coil is easily seen to be completely s
All the components of electric bell are \nmounted on a large panel. All wiring is \nvisible and parts are of large size. \nOperates on 4-6 volts DC.
Ideal for student use. With terminal posts accepting 4mm plugs. 0-19.99 V Power: 1 x 9v PP3 battery supplied
This is claimed to be 'the original' in the sense that it is made in America, by the successors to the firm who first marketed it in 1917. It is entirely metal and smartly packaged with string and sta
For demonstrating Hooke's Law, resolution of forces, kinetic energy measurement etc. Will recover from stretch to approx 400mm. Specification Size: 22 x 15mm.
Top plate measures 11 inches in diameter and can be used with bell jars up to 9 inch diameter. Constructed of cast iron, the plate is equipped with a 3/8 inch hose connection, vacuum release valve, and rubber gasket to provide
Converts muscular energy to other forms of energy. 75 mm diameter hand cranked pulley with rubber belt to drive a small pulley of 20 mm diameter to which a drive output pulley is directly attached. Pulley shafts are mounted in bearings on aluminiu
This simple unit can help the student understand the operating principle of pump and turbine. The unit consists of a rotor attached to a pulley via a shaft. It also includes 3 metal nozzles and a stopcock. When driven by a motor, the unit works as
For showing conversion of potential energy stored in twisted rubber to kinetic/electrical energy. Elastic bands are looped & stretched between pulley and support. A crank handle and pulley combined with ratchet stop allows the rubber to be wou
