The Eisco 400,000 Volt Van de Graaff Generator Kit is a powerful electrostatics demonstration system designed for physics classrooms, STEM labs, and science educators. Capable of generating up to 200,000–400,000 volts, this high-voltage generator vividly demonstrates the principles of static electricity, charge transfer, and electric fields in an engaging and memorable way.
A Van de Graaff generator works by transporting electric charge using a moving belt to accumulate high voltage on a hollow metal sphere, producing extremely high potential at very low current—making it ideal for safe educational demonstrations.
This all-inclusive electrostatics kit includes the generator and 10 interactive attachments that allow instructors to demonstrate phenomena such as hair-raising static electricity, ionization, electrostatic discharge, and charge distribution. The included accessories—such as a Faraday’s pail, electric whirl, neon tester, and pith ball apparatus—enable a wide variety of experiments that illustrate key electricity concepts.
The generator features a large 9-inch metal dome mounted on an insulated column, allowing effective charge accumulation and visible electrostatic effects. A removable discharge wand and additional accessories allow instructors to safely control and demonstrate high-voltage discharge arcs.
Ideal for middle school, high school, university physics courses, and STEM outreach demonstrations, this electrostatic generator kit transforms abstract electrical concepts into exciting, hands-on experiments that students can see and understand.
