Van de Graaff Generator Manufacturer,Supplier and Exporter in India

Van de Graaff Generator (Product Code: SLE/PHY/123) is an electrostatic generator used to build up a large static charge on a metal dome for demonstrations of static electricity in schools and colleges. Students crank it by hand, so the charge depends on how hard and how long they turn, or run it from a laboratory DC supply up to 12V; the 23 cm dome is listed at 400kV. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Van de Graaff Generator Used For?

The Van de Graaff Generator makes static electricity dramatic. As the belt runs, charge collects on the dome, and students can watch sparks jump to an earthed conductor, see strips of light paper or hair stand apart as like charges repel, and use an electroscope to show charge being transferred. Because the hand crank links effort directly to charge, it gives a true hands-on experience rather than a push-button demonstration.

For longer or steadier runs, drive it from a laboratory DC supply of up to 12V and set the belt speed to control how quickly charge builds. Work in dry air where possible, discharge the dome with an earthed conductor before anyone touches it, and keep the generator away from sensitive electronics. As a physics demonstration kit piece, it supports lessons on charge, electric fields and lightning.

What to Specify When Ordering

• Power mode — hand crank only, or also a laboratory DC power supply (up to 12V) for powered running.
• Companion items — electroscopes or other electrostatics apparatus to be quoted alongside.
• Quantity — one per demonstration room, or more for student groups.

Frequently Asked Questions

Can the Van de Graaff Generator be used without mains power?
Yes. The Van de Graaff Generator is cranked by hand with the supplied crank, so no power supply is needed for basic demonstrations. It can also be powered from a DC source by a laboratory power supply up to 12V when you want control of belt speed.

What are the dimensions and weight of the Van de Graaff Generator?
The Van de Graaff Generator measures 63 x 25 x 25 cm and weighs 5.68 kg, with a dome diameter of 23 cm. That size lets a teacher carry it between classrooms and stand it on an ordinary demonstration bench.

What voltage does the Van de Graaff Generator produce?
The Van de Graaff Generator is listed at 400kV. In practice the charge built up depends on how hard and how long the crank is turned, or on the belt speed set through the DC supply, and results also vary with conditions such as humidity.

How should the Van de Graaff Generator be used safely in class?
The Van de Graaff Generator should be operated by, or under the supervision of, a teacher. Discharge the dome with an earthed conductor before touching it, keep it away from electronic equipment, and do not let anyone with a heart pacemaker take part in demonstrations.

Who manufactures the Van de Graaff Generator?
The Van de Graaff Generator is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Schools and resellers receive quotations and after-sales help from the maker itself.

What should a Van de Graaff Generator quotation request include?
For a Van de Graaff Generator quotation, give the number of units, the delivery city or country, and whether you want a laboratory DC power supply or electroscopes included. Dealers and importers in India and international markets can request quantity quotations the same way.
