Van de Graaff apparatus generating very high voltages for electrostatic experiments.
Sparks up to 100 mm can be obtained.
The very low output current makes it a safe apparatus.
The electrons are transferred to the sphere by a non-conductive belt that passes between two rolls made from different plastics. The belt is driven using a variable motor or manually with a crank.
The sphere is easily removable, to study the device.
At the top of the sphere is a 4 mm socket designed to add accessories such as the electrostatic turnstile. Dust cover and manual included.

Technical characteristics:

• sphere Ø: 220 mm
  
• Sphere capacity: 15 pF (approximately)
  
• Power supply voltage: 230 V AC
  
  
• Dimensions : 195 x 195 x 560 mm
