Van de Graaff Generator, Adjustable Speed, (+)Dome

Without a doubt the most attention-getting week in any physical science course is when the students get an up-close experience with the Van de Graaff generator. There's a lot more to be learned, however, than just how to make your hair stand up.

Electrostatic experiments are vital to a well-rounded experience in understanding and appreciating the complexity of electricity; i.e. where charges reside, how they behave, and how they affect their surroundings.  The Van de Graaff is key in piquing the curiosity of students into this fascinating world.

A rugged unit that will develop potentials up to 350,000 volts on the polished, anodized dome. Provides the power to execute all the basic electrostatic demonstrations on an energetic and dramatic scale. The maximum continuous current is only about 10 microamperes, so the unit is quite safe.

The image above shows the N-100 Van de Graaff generator with the N-122L Discharge electrode.  They are sold separately.

Sparks of 8" are usual and may go to 12-15”.

The standard machine has a negative dome, but a positive electrode machine is available.

The unit is shipped assembled and includes an extra transport belt.

Dome diameter: 25 cm

The unit will be manufactured with a cord and plug appropriate for the destination country as determined by shipping address.
