1 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.

2 VAN DE GRAAFF GENERATOR - BASIC - NEW! A versatile Van de Graaff electrostatic generator which uses a moving silicone rubber belt to accumulate very high electrical potential and transfer it to a hollow metal charging 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, up to 8cm. This Van De Graaff Generator produces up to 220,000 Volts and comes with a polished 18cm charge collecting sphere, a 10cm discharge sphere mounted on a wand, assembled base with attached DC motor, mains power cord, electrostatics accessories kit and instructions.
