1 WIMSHURST MACHINE The ideal equipment for simple demonstration of electrostatics. No electrical power is required. The unit will quickly generate a charge with regular discharge. Under correct conditions the spark will travel up to 120mm in air between electrodes. The two plates are supported in two rigid uprights and driven by a belt in the opposite direction. The plates are heavy high resistance plastic with sectors of aluminium sheet. Two leyden jars (capacitors) are made from corning glass and aluminium foil. The apparatus is mounted on a base for easy use and transportation. Diameter of plates: 310mm Cat No. Description Price Per ECT-240-100 Wimshurst Machine 144.23 ea. 2 VAN DE GRAAFF GENERATOR STANDARD A good quality, reliable, mains operated Van de Graaff generator, for demonstrating electrostatic charge and discharge. The apparatus comprises a robust metal base, which houses the motor, with a clear acrylic column mounted on top, where the charge belt is located. On top of the column is a 220mm diameter conducting sphere (dome) which stores the electrostatic charge generated by the rollers and transferred via the charge belt. Also included is a smaller (100mm diameter) discharge sphere, mounted on an offset rod with a 4mm plug at the end, which can be inserted into the earthed 4mm socket on the base unit. The charge built up in the main dome can then be heard and seen to discharge to the smaller sphere, when sparks jump across the air gap between the two. Supplied complete with 100mm diameter discharge sphere, dust Cover and accessories kit (see ECT-450-100 for full details). Spare belt has a 730mm circumference x 48mm width. • 220mm diameter sphere • Produces up to 300KV (depending on conditions) • Base dimensions: 218 x 182 x 93mm • Overall Height: 500mm Cat No. Description Price Per ECT-400-100 Van de Graaff - Standard 357.75 ea. ECT-400-150 Spare Belt for Standard VDG 18.70 ea. 3 VAN DE GRAAFF GENERATOR - BASIC - A versatile Van de Graaff electrostatic generator which uses a moving belt to accumulate very high electrical potential onto a hollow metal sphere. The unit may be operated using the inbuilt electric motor or can be manually driven using the hand crank handle to demonstrate that its operation is independent of the mains supply. In good conditions the apparatus produces large sparks, in excess of 100mm and comes supplied with a full set of accessories, a spare drive belt, a spare rubber belt and detailed user instructions. Cat No. Description Price Per ECT-430-100 Van De Graaff Generator - Basic 389.90 ea. ECT-430-200 Spare Charge Belt for Basic VDG 27.90 ea. 4 VAN DE GRAAFF ACCESSORIES KIT Includes: hair, dancing balls, comb, whirl, oscillating sphere, neon bulb, Faraday’s pail, point discharger. These accessories are suitable for all Van de Graaff generators. Cat No. Description Price Per ECT-450-100 Van de Graaff Accessories Kit 27.50 ea.
