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 can form part of the bell-jar model of the lungs in school biology and of gas-handling set-ups in chemistry practicals. Science Lab Supplies offers them from Ambala, India, preparing quotations for schools, colleges, training institutes, distributors and tender contractors.
Specifications
The table records each property of the Y-piece on a separate row. In short, it 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, and the glass is chemical resistant and heat resistant for ordinary laboratory use.

Applications and Experiments for Y-Shaped Glass Tubes
The Y-tube can act as the windpipe and bronchi of a bell-jar lung model, as in the Human Lung Model in Bell Jar: 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 along a gentler 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, for example from the Simple Equipment for Gases that do not Dissolve in Water.
- College labs: assembly of gas and vacuum lines with rubber tubing and a Hand Vacuum Pump.
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 as the Y-pieces.
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.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code and is able to ship to buyers in Ghana, Ethiopia, Tanzania, Uganda, the UAE and Saudi Arabia. Say how many Y-pieces you need in a message through the contact page or by adding them to the enquiry cart; buyers working to a tender can check the lab tender page first.
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 balloon is tied on each 7 mm branch to represent the lungs while a rubber sheet acts as the diaphragm.
What diameter tubing fits the branches?
All three arms are 7 mm in diameter, so use rubber tubing whose bore fits tightly over a 7 mm glass tube. Wetting the glass helps the tubing slide on without force.
Who supplies the Y-Shaped Glass Tubes?
Science Lab Supplies, an Ambala-based business in India, quotes these Y-pieces in any quantity for schools, colleges, training institutes and distributors, and can price them for tenders.
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.
