Glass Bells with Corks
Product Code : SCL-CL-11492
Glass Bells with Corks (SKU SCL-CL-11492) are clear glass bell jars, 150 mm in diameter and 200 mm long, closed at the top with a cork. They can enclose a sample of air, a candle or a plant, and can form the chest cavity of the bell-jar lung model, in middle-school science, biology and chemistry classes and teacher-training labs. Science Lab Supplies arranges supply from Ambala, India for schools, colleges, training institutes, distributors and tender contractors.
Specifications
The bell jar’s size, material and closure each take a row in the table. In short, the bell is clear glass, 150 mm across and 200 mm long, so the contents stay visible during a demonstration, and the cork closes the upper opening and can be bored to take a glass tube or thermometer.

Applications and Experiments for Glass Bells with Corks
A glass bell turns a bench into a closed space that students can watch. It covers a burning candle to show that combustion needs air, encloses a plant in photosynthesis and transpiration experiments, and, with Y-Shaped Glass Tubes, balloons and a rubber sheet, becomes a working model of breathing.
- Class 7 and Class 10 biology: the bell-jar model of the lungs and diaphragm, as in the ready-made Human Lung Model in Bell Jar.
- Class 8 science: a candle burning under a jar goes out once the air supply is used.
- Class 10 biology: covering a potted plant to study the conditions needed for photosynthesis.
- Teacher-training and college labs: general enclosure for gas and air demonstrations.
Place the bell on a flat surface and let it cool after a candle experiment before lifting it. Demonstrations with flames should be carried out under supervision.
Standard Scope of Supply
Each item is a clear glass bell supplied with its cork, as the product name states. Y-tubes, balloons, rubber sheet and base plates for a lung model are not included and can be added to the enquiry as separate items on the same quotation.
Packing, MOQ and Lead Time
Ask for one bell jar for a demonstration table or several for a biology and chemistry department. Science Lab Supplies will quote the packing, delivery time and price for that quantity, and the lung-model parts and other school chemistry lab equipment in India can share the quotation.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Bell jars and model parts can be listed together in the enquiry cart, or you can describe the demonstration you are planning on the contact page; tender buyers should first read the lab tender page.
Frequently Asked Questions
Can this bell jar be used for the lung model?
Yes. A Y-shaped glass tube is passed through the cork, a balloon is tied to each branch inside, and a rubber sheet stretched over the open end acts as the diaphragm.
What size is the glass bell?
It is 150 mm in diameter and 200 mm long, made of clear glass and closed at the top with a cork that can be bored when a connection is needed.
Who supplies the Glass Bells with Corks?
Quotations for these bell jars come from Science Lab Supplies in Ambala, India, for schools, colleges, training institutes and distributors ordering a single piece or a larger lot.
Can the cork be drilled?
Cork can be bored with a cork borer to take a glass tube or thermometer; match the hole to the tube so the fit stays airtight. Rubber Stoppers of Various Diameters with Holes are a ready-bored alternative.
