What Is the Test Tube Set Used For?
Test tubes handle the small-scale tests of a biology course: Benedict’s test for reducing sugar, which needs the tube warmed in a water bath; the iodine test for starch; and enzyme work in which saliva acts on starch solution and drops are tested with iodine at intervals. The rim strengthens the mouth and gives a cleaner pour. To heat a tube, hold it in a test tube holder at an angle with the mouth pointing away from everyone, warm it gently near the liquid surface while moving it through the flame, and let it cool before washing — never plunge hot glass into cold water.
Frequently Asked Questions
How many tubes are in the set?
The listing does not state the number. JLab confirms the tube count in the quotation; tell us how many tubes each bench needs.
Can the tubes be heated directly in a burner flame?
Yes, with care. They are borosilicate glass listed as heat resistant; use a holder, heat gently and keep the tube moving, and never heat an empty or tightly stoppered tube.
How does the set differ from the single Test Tube listings?
The Biology Lab range also lists individual borosilicate test tubes with rim in the same 15 x 150 mm size. This listing is the set; state in your enquiry whether you want sets or loose tubes.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory glassware and biology equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The tubes come from JLab’s own works rather than a trading house, so schools, dealers and importers buy them factory-direct. JLab exports worldwide and ships to buyers in every region — for example Libya in North Africa, DR Congo in Central Africa, Saudi Arabia in the Middle East, Turkmenistan in Central Asia and Mexico in North America. For tenders, see the JLab lab tenders page.
