Van de Graaff Generator – Large Model with FREE Accessory Set [0495]

The Large Van de Graaff Generator is a full‑size, high‑impact physics demonstration apparatus designed to vividly illustrate the principles of static electricity. Suitable for KS3 and above, this generator is an excellent centrepiece for engaging classroom demonstrations in secondary school and sixth‑form physics.

The generator features a large conducting metal dome mounted on a clear plexiglass support column. Static charge is generated by a rubber belt driven by an electric motor concealed within the robust metal base and powered directly from the mains supply. A blue protective cover is included to keep the apparatus dust‑free when not in use, and a spare belt is available separately.

The base includes a versatile 4mm socket, allowing accessories to be mounted directly on the dome or connected to external conducting spheres for extended investigations. This model is supplied with a FREE Van de Graaff Accessory Set, greatly expanding the range of experiments and demonstrations that can be performed.

With a generous dome diameter of 220mm and the ability to produce sparks of up to 50mm, this generator provides clear, dramatic results while remaining robust and reliable for repeated school use.
