What Is the Test Tube Used For?
In the class 9 practicals, students shake a food sample with water in a test tube and add iodine to look for starch, or add hydrochloric acid to a dal extract to check for the adulterant metanil yellow. Senior and college classes run Benedict’s test for reducing sugars by warming the tube in a water bath. When heating, hold the tube in a holder, keep it no more than about a third full, warm it near the liquid surface while moving it in the flame, and point the mouth away from everyone. Clean it with a tube brush and let it drain upside down in a stand.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; test tubes break, so most labs order a class set plus spares.
- Glass type — the listing says glass; ask if your syllabus or tender requires borosilicate.
Frequently Asked Questions
What size is this test tube?
It is listed as 15 x 150 mm, which by the usual convention is the diameter and the length. It is clear glass with a rim.
How is it different from a boiling tube?
A boiling tube is wider and longer — JLab’s Boiling Tube is listed at 32 x 200 mm in borosilicate glass — so it holds more liquid and suits vigorous boiling, while this test tube is for small-volume tests.
Can it be heated directly in a flame?
The glass is listed as heat resistant, so gentle heating with a holder is normal. The glass type is not stated, so for repeated strong heating choose the borosilicate boiling tube.
Who manufactures this test tube?
JLab — Jain Laboratory Instruments Pvt Ltd — makes it at its Ambala works and quotes directly.

JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory glassware manufacturer in India, incorporated in 2017, whose works are on Hargolal Road, Ambala, Haryana. Test tubes are produced there rather than bought from a trader, so schools, colleges, dealers and importers order factory-direct. JLab exports worldwide and ships to buyers in every region — for example Norway in Northern Europe, Nigeria in West Africa, Egypt in North Africa, DR Congo in Central Africa and Hong Kong in East Asia.
