Glass Bell on The Support Manufacturer,Supplier and Exporter in India

Glass Bell on The Support (Product Code: SCL1431/014) is a transparent glass bell with a handle, at least 200 mm in diameter and 250 mm high, standing on a plastic holder fitted with a sealing gasket. Placed over small apparatus and used with a vacuum pump, it forms a clear, sealed enclosure in which students can watch what happens as the air is taken away. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a school laboratory equipment supplier in India for air-pressure and vacuum lessons.

Specifications

Typical Use

Typical experiments under the bell include a partly blown-up balloon that swells as the surrounding air is pumped away, warm water that starts to boil at reduced pressure, and a small ringing device whose sound fades as the air thins. Once the bell has been evacuated, students can also try to lift it by the handle and feel how firmly the outside air presses it onto the gasket – a memorable way to show that atmospheric pressure is real and large.

Before each use, inspect the glass for chips or cracks and never evacuate a damaged bell. Keep the rim and the sealing gasket clean and free of grit so the seal holds, and let air back in slowly before lifting the bell off the support. Carry it with one hand on the handle and the other under the glass.

Frequently Asked Questions

What size is the glass bell?
It has a minimum diameter of 200 mm and a minimum height of 250 mm. We can confirm the exact dimensions of the supplied bell in the quotation.

Is a vacuum pump included?
No. The item consists of the glass bell with handle and the plastic holder with sealing gasket; a pump is ordered separately.

How does it connect to my pump?
The connection arrangement depends on the pump you use. Please describe your pump through the contact page so we can confirm the connection before dispatch.

Why is the bell hard to lift after the air is removed?
Atmospheric pressure outside pushes the bell onto the gasket. Let air back in slowly and it lifts off easily.

How should the gasket and glass be cared for?
Wipe the gasket and rim clean after use, store the bell upright on its support away from the bench edge, and check the glass for damage before every evacuation.

Can we order several sets for a school group or export?
Yes. We quote multiple sets for institutions and distributors in India and international markets; include product code SCL1431/014.
