Glass Rod with Rubbing Material
Product Code : SCL-CL-11871
Glass Rod with Rubbing Material (SKU SCL-CL-11871) is a glass rod paired with a matching piece of cloth for producing static electricity by friction. When the two are rubbed together, electrons move from the glass to the cloth, leaving the rod positively charged. The pair suits Class 8 lessons and Class 10–12 physics demonstrations. Science Lab Supplies takes enquiries for it at Ambala, India from schools, colleges, training institutes, distributors and tender contractors.
Specifications
All the facts about this glass rod and cloth pair are set out in the table. In short, rubbing transfers electrons from glass to cloth, so the rod ends up positive and the cloth negative, and the charged rod can then attract small neutral objects such as paper bits, dust or other lightweight materials.

Applications and Experiments for the Glass Rod with Rubbing Material
This pair gives students a positive charge to work with, so it complements a negatively charged rod in attraction and repulsion tests. It covers static electricity in NCERT Class 8 science, electric charges and fields in Class 12 physics, and hands-on demonstrations in school laboratories and teacher-training sessions.
- Class 8 science: attracting bits of paper with a rubbed rod.
- Class 12 physics: two kinds of charge and the rule that like charges repel, using the spheres, strips and woollen cloth of the Magnetic Kits set.
- Electroscope practicals: charging the instrument positively, then comparing the effect with charge drawn from a Van De Graaff Generator under supervision.
Standard Scope of Supply
Each set is supplied as the glass rod with its corresponding piece of cloth, ready for rubbing. Test objects, an electroscope and a second rod of another material are separate items, and any of them can be requested on the same quotation so the whole electrostatics bench is priced together.
Packing, MOQ and Lead Time
Ask for one set for demonstration use or several for group work; every quotation spells out the packing, delivery time and price for that quantity. As a laboratory glassware supplier in India, Science Lab Supplies can add other glass items from your list to the same quotation for one delivery.
Science Lab Supplies has an Importer-Exporter Code and can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Pricing for the rod and cloth can be requested by filling the enquiry cart or by writing through the contact page, while the lab tender page explains how tender quotations are prepared.
Frequently Asked Questions
Why does the glass rod become positively charged?
Rubbing moves electrons from the glass onto the cloth. The glass is left short of electrons, so it carries a positive charge, while the cloth gains them and becomes negative.
What can the charged rod attract?
Small neutral objects such as paper bits, dust particles or other lightweight materials. It makes a simple first demonstration of electrostatic attraction and needs nothing beyond the rod and its cloth.
Who supplies the Glass Rod with Rubbing Material?
The set is quoted by Science Lab Supplies and leaves from its base in Ambala, India. Schools, colleges, training institutes, distributors and tender contractors can request a quotation for any quantity.
How should the glass rod be handled?
Hold it by one end, keep it dry and store it where it cannot roll off the bench. Replace any chipped rod, since broken glass edges are sharp and can cut.
