Van de Graaff Generator – Full Size with FREE Accessory Set

This premium Full‑Size Van de Graaff Generator is designed for high‑impact electrostatics demonstrations, producing very high DC voltages while remaining completely safe to use thanks to its extremely low output current. The unit features a large 220mm aluminium collector sphere, which can be easily dismantled to reveal the internal workings—perfect for teaching how the generator operates.

Static charge is produced using a rubber belt and two plastic rollers, while the lower roller is powered either by a 230V motor with three selectable speeds or by the integrated manual hand crank. An earthing socket is included on the motor housing for grounding or connecting additional accessories such as a secondary conducting sphere.

This impressive generator is supplied with a comprehensive FREE accessory set that greatly expands the range of electrostatic experiments that can be demonstrated.

Overall dimensions: 230mm (W) × 220mm (D) × 690mm (H) Weight: 6.5kg
