Friction Bar Glass Manufacturer,Supplier and Exporter in India

Product Code : SCL-EI-10641

The Friction Bar Glass is an electrostatics teaching rod used for generating static charge by friction in school physics laboratories. It is intended for students, teachers, STEM trainers, and laboratory technicians who need a reusable glass rod for demonstrating charge transfer, attraction, repulsion, and basic static electricity effects.

Product Description

The Friction Bar Glass helps learners observe how rubbing suitable materials together can transfer charge and create electrostatic effects. In classroom demonstrations, the glass bar is commonly rubbed with silk and then brought near pith balls, small paper pieces, or an electroscope to show attraction, repulsion, or charge detection.

This product is suitable for Physics Lab Equipment, electrostatics kits, school science laboratories, and STEM classrooms. It can also be supplied with related General Lab Equipment for institutional lab setups. The final length, diameter, glass type, end finish, and included accessories should be confirmed before publication.

How to Use the Friction Bar Glass

1. Place the glass friction bar and silk cloth on a clean, dry laboratory bench.
2. Ensure both materials are dry, because moisture reduces static charge buildup.
3. Hold one end of the glass bar and rub the other end with silk several times.
4. Bring the charged glass bar near paper pieces, pith balls, or an electroscope.
5. Observe attraction, repulsion, or electroscope leaf movement as per the experiment.
6. Discharge the bar safely and store it after the activity.

Safety note: Handle glass carefully to avoid breakage. Use only for low-energy school electrostatics experiments and keep it away from wet benches, impact, flames, and high-voltage apparatus not designed for student use.

Care & Maintenance

• Store the glass bar in a padded, dry, labelled box after use.
• Keep the surface clean, dry, and free from oil, dust, and laboratory chemicals.
• Clean gently with a soft dry cloth; do not use abrasive cleaners.
• Replace the bar if it becomes cracked, chipped, scratched, or unsafe to handle.

Frequently Asked Questions

What is a Friction Bar Glass used for?

A Friction Bar Glass is used to generate static charge by friction in school physics experiments. It helps demonstrate charge transfer, attraction, repulsion, and electroscope response.

What material is used to rub the glass bar?

A glass friction bar is commonly rubbed with silk cloth in electrostatics demonstrations. The supplied friction material should be confirmed if it is included in the kit.

Does a glass rod become positive or negative when rubbed with silk?

In standard classroom electrostatics demonstrations, a glass rod rubbed with silk becomes positively charged, while the silk becomes negatively charged.

Is the glass friction bar suitable for school students?

Yes. It is suitable for supervised school and STEM experiments when handled carefully and used in dry laboratory conditions.

Does the bar include an electroscope or pith balls?

The standard listing should be treated as the glass friction bar only unless an electroscope, pith balls, silk cloth, or full electrostatics kit is specifically mentioned.

What details should be confirmed before purchase?

Confirm bar length, diameter, glass type, end finish, quantity, packaging, and whether silk cloth or electrostatics accessories are included.
