Glass Tubes of Different Diameters
Product Code : SCL-CL-11484
Glass Tubes of Different Diameters (SKU SCL-CL-11484) are straight 100 mm glass tubes offered in six diameter ranges, from 5–6 mm up to 12–13 mm. They can serve as delivery tubes, as connectors pushed through bored stoppers, and as stock for practising glass cutting and bending in school and college chemistry. Science Lab Supplies sends these tubes out of Ambala, India against quotations for schools, colleges, training institutes, distributors and tender contractors.
Specifications
Each fact about these 100 mm tubes appears as its own row in the table. In short, every tube is plain, chemical-resistant glass of the same length, and the six diameter ranges let you match a tube to the hole in a stopper or the bore of a rubber connector for gas and reagent work.

Applications and Experiments for Glass Tubes of Different Diameters
Straight glass tubing can form the connecting pieces of gas and distillation set-ups. Narrow sizes fit single-hole stoppers and carry gas to a test tube or jar; wider sizes act as short sleeves, guards or joints. Students can also learn to cut, bend and fire-polish tubing with these pieces.
- Class 10 science: delivery tubes for the hydrogen and carbon dioxide tests, alongside the Simple Appliances for Cooking Gas Lighter than Air.
- Class 11 chemistry: basic laboratory techniques of cutting, bending and fire-polishing glass tubing.
- Gas-preparation and collection set-ups such as the Simple Gas Preparation Kit, built from flasks, stoppers and rubber tubing.
- B.Sc. labs: short connectors in distillation assemblies with a Straight Cooler (Condenser) and in filtration set-ups.
Wet the tube and hold it in a cloth when pushing it into a stopper, and fire-polish cut ends; broken glass tubing causes deep cuts, so students should work under supervision.
Standard Scope of Supply
The item is supplied as 100 mm glass tubes in the six diameter ranges set out above. Tell us which diameters you need and how many of each, and the quotation shows them line by line; stoppers and rubber tubing are separate items that can be quoted with them.
Packing, MOQ and Lead Time
Order a handful of tubes for one bench or a mixed stock for a whole department. Science Lab Supplies prepares a quotation showing the packing, delivery time and price for exactly those quantities, and other chemistry lab equipment in India can be added to it.
Science Lab Supplies, a registered exporter with an Importer-Exporter Code, can ship to buyers in Nigeria, Kenya, Ghana, Ethiopia, Tanzania and Uganda. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Note the diameters and counts you want in the enquiry cart or in a message from the contact page; a tender order follows the steps on the lab tender page.
Frequently Asked Questions
Which diameters are available?
Six ranges: 5–6 mm, 6–7 mm, 7–8 mm, 8–9 mm, 10–11 mm and 12–13 mm, all 100 mm long. Choose the size that matches your stopper holes and rubber tubing.
Can the tubes be bent in a flame?
Glass tubing is bent by heating it evenly in a burner flame and shaping it slowly. This should be done by or under a trained teacher, with the hot glass left to cool on a heat-proof mat.
Who supplies these glass tubes?
The tubes are quoted by Science Lab Supplies, an Ambala, India business that fills small bench orders and bulk department lists for schools, colleges, training institutes and distributors alike.
Can I mix several diameters in one order?
Yes. List the quantity you need for each diameter range, and every range will appear as a separate line with its own price on one quotation.
