Apparatus for Distributing Electric Charges (Product Code: SCL-353/027) is an electrostatics demonstration set used to show how electric charge is produced by rubbing, shared by contact and distributed over conductors, in secondary school physics lessons. Four metal spheres on plastic insulating handles, polyethylene and celluloid tapes, a friction cloth and a 200 mm gold-leaf electroscope let the class create charge and detect it. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Electrostatics lessons start with charging by friction: rubbing the polyethylene or celluloid tape with the friction cloth leaves the two materials with opposite charges, which students detect by bringing the charged object to the gold-leaf electroscope and watching the leaves spread. The metal spheres on their insulating handles then show how charge moves between conductors — touching a charged sphere to an uncharged one shares the charge between them, and the electroscope confirms the result.
The two aluminium cans take the lesson on to where charge sits on a conductor: tests with the insulated spheres show that charge gathers on the outer surface of a hollow can rather than inside it. Work in dry conditions, since humid air lets charge leak away quickly, hold the spheres only by their insulating handles, and discharge everything by touching it to earth between experiments. For schools stocking physics lab equipment in India and overseas, the set covers the core electrostatics topics taught in secondary school.
The Apparatus for Distributing Electric Charges is manufactured by Jain Scientific Equipments Private Limited — ScienceLab to its customers — as the original equipment manufacturer. Registered with the Ministry of Corporate Affairs under CIN U29309HR2020PTC087597, the company assembles this electrostatics set at its factory at 449, HSIIDC Industrial Area, Saha, Ambala, which operates under Factory Licence AMB-ONLINE-CHD-J-414.
Schools, colleges, dealers and importers are supplied direct, and spare tapes, cans or a replacement electroscope can be requested from the manufacturer — ask us. Read more on the ScienceLab company profile.

What is included in the Apparatus for Distributing Electric Charges?
The Apparatus for Distributing Electric Charges (SCL-353/027) includes four metal spheres on plastic insulating handles, an insulating handle, an insulating handle for the electroscope plates with foil, polyethylene tape, nylon wrap, two aluminium cans, celluloid tape, a wire stirrer, a friction cloth, a chrome wire hook and a 200 mm gold-leaf electroscope.
How is electric charge produced with this set?
With the Apparatus for Distributing Electric Charges (SCL-353/027), charge is produced by friction: rubbing the polyethylene or celluloid tape with the friction cloth charges both materials oppositely, and the charge can then be transferred to the metal spheres or the electroscope.
What does the gold-leaf electroscope show?
The 200 mm gold-leaf electroscope in the Apparatus for Distributing Electric Charges (SCL-353/027) shows whether an object is charged: when charge reaches the electroscope, its leaves repel each other and spread apart, and the size of the spread gives a rough idea of the amount of charge.
Why do electrostatic experiments fail on humid days?
Moist air conducts charge away, so demonstrations with the Apparatus for Distributing Electric Charges (SCL-353/027) work far more reliably in a dry room. Keep the tapes, cloth and insulating handles clean and dry, and warm them gently if they feel damp.
Who manufactures the Apparatus for Distributing Electric Charges?
The Apparatus for Distributing Electric Charges (SCL-353/027) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and is supplied directly to schools, dealers and importers.
Can the set be ordered in bulk or for export?
Yes. The Apparatus for Distributing Electric Charges (SCL-353/027) can be supplied in multi-set quantities to schools, colleges, dealers and importers in India and international markets. Send the quantity and destination through the contact page for a quotation.
