Y-Shaped Glass Tubes
Product Code : SCL-CL-11486
Y-Shaped Glass Tubes (SKU SCL-CL-11486) are 7 mm glass Y-pieces that divide one line into two branches at a shallow angle, or bring two streams together. They are a familiar part of the bell-jar model of the lungs in school biology and of gas-handling set-ups in chemistry practicals. Science Lab Supplies supplies them out of Ambala, India for schools, colleges, training institutes, distributors and tender contractors.
Specifications
Each Y-piece is formed from glass tube with a stem and two angled branches, all 7 mm in diameter so that rubber tubing, balloons or stoppers fit over them. The specification gives the glass chemical resistance and heat resistance for ordinary laboratory use.

Applications and Experiments for Y-Shaped Glass Tubes
The Y-tube is widely used as the windpipe and bronchi of the bell-jar lung model: its stem passes through the cork and a balloon on each branch inflates as the rubber base is pulled down. In chemistry it splits or merges gas flows with a smoother path than a right-angled joint.
- Class 7 and Class 10 biology: the bell-jar model showing how breathing moves air into the lungs.
- Class 11 biology: explaining the role of the diaphragm with the same model.
- Chemistry practicals: sending one gas to two reagents, or combining two gases into one tube.
- College labs: general assembly of gas and vacuum lines with rubber tubing.
Standard Scope of Supply
The Y-Shaped Glass Tubes are supplied as separate glass Y-pieces as described in the table. Bell jars, balloons, rubber tubing and clamps are not part of the item; list any you need and they are quoted on the same sheet.
Packing, MOQ and Lead Time
Whether you want a single Y-piece for a lung model or a box of spares for a department, the quotation sets out the packing, delivery time and price for that number. It can also carry the rest of your school chemistry lab equipment in India, so one order covers the bench.

Frequently Asked Questions
Can this Y-tube be used for the bell-jar lung model?
Yes. The stem goes through the cork or stopper of the bell jar and a small balloon is tied on each 7 mm branch to represent the lungs.
What diameter tubing fits the branches?
All three arms are 7 mm, so use rubber tubing whose bore fits tightly over a 7 mm glass tube.
Who supplies the Y-Shaped Glass Tubes?
They are supplied by Science Lab Supplies from Ambala, India, which quotes schools, colleges, training institutes and distributors in any quantity.
Is the glass safe for students to handle?
Handle it like any glassware: fit tubing gently, do not bend the branches, and keep broken pieces away from students. Assembly should be done with a teacher present.
Related Glass Tubes and Model Parts
The Y-tube works with a bell jar and cork for the lung model and with tubing and clamps for gas work. These four items from the Chemistry Lab range cover both uses and can be priced together with it from one laboratory glassware supplier in India.
- Glass Bells with Corks — the jar for the breathing model.
- T-Shaped Glass Tubes — right-angled branch in the same 7 mm size.
- Rubber Tube (Laboratory) — connects the branches to apparatus.
- Elastic Clamp for Rubber Pipes (Mohr Clamp) — pinches a branch shut.
