Aepinus Condenser

It consists of two adjustable plates 100 mm dia. insulated handle and a glass dielectric plate. Fitted on stable base.

Butterfly Net-Faraday

To show that electrical charge resides on external surfaces of a conductor. Fabric net with cord on insulating pillar with base.

Conductors Set of three

Made of brass, interchangeable on pillars, fitted with insulators of ebonite on base. Spheres 5 cm dia., Cylinder 12.5 x 5 cm dia., Cone 10 x 5 cm length x diameter.

Electric Whirl

For demonstrating the effect of electric discharge from points. The apparatus has a 95 mm diameter, Three-pointed star wheel with all the points curved in one direction. The wheel rotates freely on a pivot point mounted on a short stand and the stand is provided with a 4 mm connection socket.


Useful for individuals and small groups. The plastic plate is easy to use and store. Also includes a metal plate for charge induction and a plastic handle to transfer the charge to other apparatus. Size of plastic plate 15 cm approx.

Electroscope Demonstration

For the demonstration of static potentials. Available with charging ball plus a set of condenser plates with insulated rod. Ring diameter 150 mm

Electroscope-Gold Leaf

A glass conical flask, brass rod with disc and gold leaf attached supported rubber cork

Electrostatic Friction Rod Kit

This electrostatic kit provides the necessary tools to free both positive and negative charges for exploration into electrostatic forces. Students can experiment with different combinations of cloth and rod materials to explore how each manufactures charge carriers.
Instruction manual included.
Kit includes:
-3 fabric cloths (wool, cotton, silk)
-3 rods (glass, ebonite, perspex)

Electrostatics Kit

This kit is ideal for small group experiments in electrostatics. The set is built around the special, dual-purpose electroscope, which in addition to being useful for general electrostatic experiments, is capable of performing measurements of the activity of weak radio-active materials. Positive and negative charges can be produced with included acetate strips and woolen cloths.
A great variety of experiments can be performed including determining types of charge, measuring the amount of conducted or induced charge with the gold leaf electroscope or by using the polystyrene spheres as hollow conductors, and using the proof plane to investigate the distribution of charges on conductors.

Friction Rod Compound

Half glass half brass, length approx. 30 cm, dia. 13 mm

Friction Rod Glass

Length approximate 30 cm, dia. 13 mm

Gold Leaf Electroscope

This gold leaf electroscope is great for hands on experience with electrostatic principles in physics classrooms and labs. The solidly constructed sheet anodized aluminum walls of the electroscope are mounted on a plastic base. Front glass window slides up to allow insertion of ionizing material in chamber. Transparent scale is attached inside chamber to measure the deflection of the gold leaf.
. Comes with two gold leaf sheets. Fitted with 4mm socket. Assembled, the electroscope measures 6.5 x 3.75 x 2.75 inches.

Paraller Plate Capacitor Demonstration

To study the principle of capacitance, its relationship with charge and voltage, its dependence on surface area of conductors and dielectric medium between two plates. It consists of 120mm circular metal discs mounted on insulated supports that slide on a extruded aluminium section to adjust the distance between the two discs. This distance can be easily known by reading their respective positions along the scale fixed on the aluminium section. Supplied with three different dielectric materials - glass, cardboard, and lucite.

Proof Plane

Consisting of an ebonite rod with brass disc of 50 mm dia.

Wimshurt Machine

Consists of transparent plates with radial aluminium segments driven in opposite directions by hand wheel and belt, with two leyden jars, mounted on moulded ABS base.
Two transparent plates are supported in two rigid uprights and driven by belt in opposite direction. They are heavy, high resistance plastic with sectors of aluminium sheet. Two leyden jars (condensers) made form corning glass and aluminium foil. The whole is mounted on moulded ABS base.
