Test tubes of this size carry out most small-scale reactions in a school lab: dry and wet tests in salt analysis, flame heating of solids, colour changes with indicators, and biology food tests such as starch with iodine or reducing sugars with Benedict’s solution. A rack of these tubes lets each student group run several tests side by side and compare results.
The rimless mouth takes a rubber or cork stopper neatly and sits well in racks. When heating, hold the tube with a test tube holder at an angle, keep the mouth pointed away from people, fill it no more than about one-third, and move it gently in the flame so the liquid does not bump.
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer of these test tubes and makes them at its own licensed factory at Saha, Ambala, Haryana. Schools and dealers ordering class quantities are quoted by the producer, and can return to the same maker when breakages mean a set must be replenished. The ScienceLab profile page gives more about the company.
