What Is the Test Tube Brush Used For?
Test tubes are among the most-used vessels in a school chemistry lab, and qualitative tests such as the salt analysis practicals in class 11 and class 12 chemistry leave coloured precipitates and films inside them. After rinsing out the contents, push the brush in with water and a little laboratory detergent, twist it to scrub the walls and the rounded bottom, rinse with tap water and then distilled water, and stand the tube upside down in a test tube stand to drain. Biology and school science labs use the same routine for tubes from food tests and simple culture work.
Let heated tubes cool before cleaning, and do not ram the brush against the bottom of a tube — the wire end can crack thin glass. Rinse the brush after use and let it dry before storage.
What to Specify When Ordering
- Test tube size — give the diameter and length of the tubes you use so JLab can quote the right standard size.
- Quantity — the minimum order is 10 brushes; many labs supply one per bench.
- Stands and holders — test tubes, test tube holders and stands can be added to the same enquiry.

Who manufactures it?
Jain Laboratory Instruments Pvt Ltd (JLab), at its works in Ambala, Haryana, India.
OEM Manufacturer
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes this test tube brush. The company was incorporated in 2017 and manufactures chemistry, biology and school lab equipment at its own works on Hargolal Road, Ambala, Haryana, so its brushes are not bought in from traders: schools, colleges, dealers and importers order factory-direct, each brush is inspected by eye before dispatch, and repeat orders go back to the same maker. JLab exports worldwide and ships to every region — for example Slovenia in Southern Europe, Taiwan in East Asia, Ethiopia in East Africa, the Czech Republic in Eastern Europe and Nepal in South Asia. See the JLab lab tenders page for tender information.
