Ebonite Rod
Ebonite Rod (Product Code: SCL-363/080) is a round black ebonite rod used to produce static charge by friction in school and college physics laboratories. Rubbed with fur or wool, it picks up a negative charge, which makes it a standard partner for electroscopes in electrostatics demonstrations; rods are offered in different diameters. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Ebonite Rod Used For?
Ebonite is a hard vulcanised rubber and a good insulator, so charge produced on its surface by rubbing stays there long enough to be studied. Students rub the rod with fur or wool and bring it near small pieces of paper, a suspended pith ball or the disc of a gold leaf electroscope to show attraction, repulsion and charging by contact or induction.
Pairing it with a glass rod rubbed with silk shows that two kinds of charge exist, because the two charged rods attract each other. Electrostatic experiments work best in dry air, so wipe the rod clean and dry before use and avoid touching the rubbed end. It is basic physics lab equipment for electrostatics lessons in schools across India.
What to Specify When Ordering
- The diameter you need, since rods are offered in different diameters.
- The length required, as it is not stated in the listing.
- Quantity, and whether rubbing cloths or an electroscope should be quoted with it.
Supplier
Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies ebonite rods from its base in Ambala, Haryana, to schools, colleges, institutions and dealers in India and international markets. Ordering the rod together with electroscopes and other electrostatics items means one supplier and one quotation for the whole set. Find out more on the company profile.
Related Physics Lab Equipment
Electrostatics lessons combine charging rods, rubbing materials and a detector. Items used alongside the ebonite rod:
- Gold Leaf Electroscope — detects and compares the charge on the rod.
- Friction Rod, Glass/Brass, 300mm — a glass rod for producing the opposite charge.
- Friction Cloth, Cotton — a cloth for rubbing charging rods.
- Friction Rod, Perspex — another insulating rod for comparing charging behaviour.

Frequently Asked Questions
What is the Ebonite Rod made of?
The Ebonite Rod is made of ebonite, a hard black vulcanised rubber, and is round in shape. Ebonite is a good electrical insulator, which is why the rod holds the charge produced on it by rubbing during electrostatics experiments.
What charge does an Ebonite Rod acquire when rubbed?
An Ebonite Rod rubbed with fur or wool becomes negatively charged, because electrons transfer from the fur to the ebonite. A glass rod rubbed with silk becomes positively charged, so the two are used together to show like and unlike charges.
Which diameters of Ebonite Rod are available?
The Ebonite Rod is offered in different diameters, but the listing does not give specific sizes or lengths. Tell us the diameter and length you prefer through the contact page, and we will confirm what can be supplied with your quotation.
Who supplies the Ebonite Rod?
The Ebonite Rod is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), based in Ambala, Haryana, India. The company supplies it to schools, colleges, institutions and dealers in India and international markets, together with electroscopes and other electrostatics apparatus.
Why do experiments with the Ebonite Rod sometimes fail?
Experiments with the Ebonite Rod work poorly in humid weather, because a thin film of moisture lets the charge leak away. Wipe the rod dry, use a dry rubbing cloth, and perform the demonstration away from open windows, kettles or other sources of steam.
Can the Ebonite Rod be ordered in class quantities?
Yes, the Ebonite Rod can be quoted in class quantities for schools, colleges and dealers. Send the number of rods, preferred diameter and delivery location through the contact page to receive a quotation from ScienceLab.
