Test Tube
Test Tube (Product Code: MSRC1062) is a 16 x 150 mm rimmed tube made of clear, heat-proof borosilicate glass 5.1, used for holding, mixing and gently heating small quantities of liquids and solids during practical work. Students carry out colour-change tests, small reactions and precipitation checks in it, while teachers and technicians use it for sample handling and quick trials. Schools, colleges and testing labs that buy borosilicate laboratory glassware in India can order it from Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Typical Use
In school and college chemistry this tube is the everyday vessel for qualitative analysis: adding a few drops of reagent to a salt solution, watching for a precipitate or colour change, warming a mixture to speed up a reaction or testing a gas given off at the mouth. Biology classes use the same tube for food tests and enzyme activities. Its clear glass lets a whole class see the result, and the rim gives a firm lip for pouring and for a holder to grip.
As with all chemistry lab glassware for India’s schools, safe technique matters: fill only a small part of the tube when heating, hold it with a test tube holder at an angle, keep the mouth pointed away from people, and move it gently through the flame rather than holding it in one spot. After use, rinse promptly, scrub with a test tube brush and leave it upside down on a drying rack so no residue dries inside.

Frequently Asked Questions
What are the dimensions of this test tube?
It measures 16 x 150 mm with a wall thickness of 1.0 mm, and it has a rim at the mouth.
Can it be heated directly over a burner?
Yes. It is made of heat-proof borosilicate glass 5.1. Warm it gradually, keep it moving in the flame and avoid putting a hot tube onto a cold wet surface.
Is it resistant to laboratory chemicals?
It is chemical resistant for routine acids, salts and indicators used in teaching labs. Like all glass, it should not be used with hydrofluoric acid, and hot concentrated alkalis will slowly etch it.
How should the tubes be cleaned and stored?
Rinse soon after use, scrub with a test tube brush and a mild detergent, rinse with clean water and dry the tubes upside down on a rack or drying pegs.
How are the tubes packed and sold?
Pack quantities are confirmed at the time of quotation. Tell us how many tubes you need through the contact page.
Can you supply larger quantities for schools or overseas buyers?
Yes. ScienceLab supplies institutions in India and international markets; include the quantity and delivery destination in your enquiry.
