Ebonite Rod

Product Code : SCL-CL-11870

Ebonite Rod (SKU SCL-CL-11870) is a hard-rubber rod supplied with a matching piece of cloth for charging by friction, the classic starting point for static electricity lessons. Rubbed with the cloth, it picks up a charge that can attract small objects or be detected with an electroscope. Middle-school science and Class 10–12 physics teachers use it for demonstrations and student practicals. Science Lab Supplies sends it from Ambala, India to schools, colleges, training institutes, distributors and tender contractors.

Specifications

Ebonite is vulcanised hard rubber, an insulator, so charge produced by rubbing stays on the rod instead of leaking away through the hand. Each rod comes with its own piece of cloth, giving a ready pair of materials for charging by contact and friction in the classroom.

Applications and Experiments for the Ebonite Rod

The rod is used to show that rubbing two materials together separates charge, and that like charges repel while unlike charges attract. Paired with an electroscope it detects charge and shows induction, topics found in NCERT Class 8 science and the electrostatics chapter of Class 12 physics.

• Class 8 science: charging by rubbing and attracting small paper pieces.
• Class 10–12 physics: attraction and repulsion between charged rods.
• Electroscope work: charging by contact and by induction.
• B.Ed. and teacher-training sessions on demonstrating electrostatics.

Static experiments are most reliable in dry air; keep the rod and cloth clean and dry between lessons.

Standard Scope of Supply

Each Ebonite Rod is supplied with its corresponding piece of cloth, ready for charging by friction. An electroscope, glass rod or suspended test objects are separate items, and any optional accessories you ask for are shown on the quotation next to the rod.

Packing, MOQ and Lead Time

A quotation can be for a single rod for a teacher's desk or a set for every student group. Science Lab Supplies lists packing, delivery time and price for the quantity you name, and school chemistry lab equipment in India from the same list can be quoted together.

Under its Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Zambia, Rwanda, South Africa, Qatar, Sri Lanka and Vietnam. Start an enquiry from the contact page, collect items in the enquiry cart, or check the lab tender page for institutional purchasing.

Frequently Asked Questions

What charge does an ebonite rod gain when rubbed?
In the usual textbook demonstration, rubbed ebonite gains electrons and becomes negatively charged, the opposite of a rubbed glass rod. Using both rods lets students show repulsion and attraction.

Is a rubbing cloth included?
Yes. The rod comes with its corresponding piece of cloth, so it can be charged straight away.

Who supplies the Ebonite Rod?
Science Lab Supplies supplies the rod from Ambala, India, quoting it directly to schools, colleges, training institutes, distributors and tender contractors in single pieces or class quantities.

Why does the demonstration sometimes fail?
Moist air lets charge leak away quickly. Rub briskly, work in a dry room and keep the rod clean for clearer attraction and electroscope results.

Related Electrostatics Items

Static electricity lessons need a second charged material, a way to detect charge and light objects to move. The four items below round out an electrostatics kit with the ebonite rod and can be quoted together on one enquiry.

• Glass Rod with Rubbing Material — takes the opposite charge for attraction tests.
• Electroscope — detects the charge on the rod.
• Balls Styrofoam — light foam balls to hang on thread.
• Demonstration Faraday Rage — mesh cage for electrostatic shielding.
