What Are the Test Tubes Used For?
Test tubes are the basic reaction vessel of practical science: in class 6 to class 10 they hold the reactions, indicator tests and food tests students carry out, and in class 11 and class 12 chemistry they are used for the wet tests of salt analysis and for heating small amounts of solids. The 75 mm tubes suit spot tests with a few drops of reagent, the 150 mm tubes take larger volumes, and the 150 x 24 mm size is the wider kind often called a boiling tube. Borosilicate glass copes with direct heating in a burner flame better than soda glass, which makes these tubes suitable for heating work.
When heating, fill the tube no more than about a third, hold it in a test tube holder at an angle with the mouth pointing away from everyone, and move it gently in the flame so the contents do not bump. A rim makes pouring easier and helps the tube rest in a holder, while rimless tubes take stoppers and caps more evenly. Clean the tubes with a test tube brush and let them dry upside down on a rack.
What to Specify When Ordering
- Size and form — the length x outside diameter from the table, and whether you need the rimless version where both exist (150 x 16 mm).
- Quantity — the minimum order is 10 units; confirm the pack size, and allow spares for breakage in student practicals.
- Rim type — ask JLab to confirm the mouth of the first size group if it matters for your stoppers or holders.
- Holders, racks, brushes and stoppers — add them to the same enquiry so the practical set is complete.
Frequently Asked Questions
Which test tube sizes are listed?
Four sizes — 75 x 12, 150 x 16, 150 x 18 and 150 x 24 mm — and three rimless sizes: 75 x 10, 100 x 12 and 150 x 16 mm.
What do the dimensions mean?
The first figure is the length and the second the outside diameter, both in millimetres. The wall is 1.0 mm on the smaller tubes and 1.2 mm on the 150 mm tubes, as shown in the size table.
Are these test tubes rimmed or rimless?
Three sizes are listed as rimless. The listing does not state the mouth of the other four sizes, so ask JLab to confirm before ordering if you need rims.
Can they be heated directly in a Bunsen flame?
Yes, with normal care. They are borosilicate glass, which withstands direct heating and temperature change better than soda glass; heat gently, keep the tube moving and point the mouth away from people.
Which stopper fits these tubes?
It depends on the size. JLab’s rubber corks are listed for test tubes and 24 mm boiling tubes; give the tube size in your enquiry and JLab will match the stopper.
How do they differ from the Test Tubes Borosilicate listing?
That listing gives rimmed tubes by capacity, from 8 ml to 70 ml, without dimensions. This one gives length, outside diameter and wall thickness, and includes rimless sizes.
What information does an export quotation need?
Each size and the quantity, whether rimless, the destination country and port or city, delivery terms such as FOB or CIF, packing or labelling requirements, and any tender reference.
Who manufactures these test tubes?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes them at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a borosilicate glassware and lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. These test tubes are produced at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy factory-direct, each tube is visually inspected before it is packed, and repeat orders in the same sizes come from the same maker. JLab holds CIN U29309HR2017PTC069123 and MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise). JLab exports worldwide and ships to buyers in every region — for example the Philippines in Southeast Asia, Sierra Leone in West Africa, Kenya in East Africa, Turkmenistan in Central Asia and Qatar in the Middle East. Tender details are on the JLab lab tenders page.
