Test Tube Clamp (SKU SCL-CL-11542) is a wooden holder that grips a test tube so it can be heated over a flame, or moved while hot, without the tube being touched by hand. It is a basic item in school science and chemistry practicals up to Class 12 and in college teaching laboratories. Schools, colleges, tender contractors and distributors can order it as school chemistry lab equipment from Science Lab Supplies, which dispatches it out of Ambala, India.
Specifications
The table below sets out each specification of this wooden test tube holder. In short, it is made of wood, a material that conducts heat slowly and so stays comfortable in the hand, and it holds one test tube firmly near the mouth while the lower end is warmed, shaken or poured.

Applications and Experiments for the Test Tube Clamp
The clamp is used whenever a test tube has to be heated or handled hot: warming solids and solutions, watching colour changes and gas release, and carrying out simple ion tests. It suits NCERT science practicals from Class 6 onward, Class 11–12 salt analysis and B.Sc. inorganic chemistry work.
- Class 6–10 science: heating substances in a rimless 12 x 100 mm Test Piece to observe physical and chemical changes.
- Class 11–12 chemistry: dry heating tests and preliminary tests in qualitative salt analysis over a Laboratory Spirit Burner with a 100 ml metal housing.
- B.Sc. inorganic practicals: warming test solutions during group analysis of cations and anions, then cleaning each tube with a nylon Brush for Washing Test Tubes.

Frequently Asked Questions
What is a test tube clamp used for?
It holds a test tube while the tube is being heated or is too hot to touch, so students can warm, shake or pour the contents without burning their fingers or dropping the glass.
Is this clamp made of wood or metal?
This model is wooden. Wood is a poor conductor of heat, so the handle stays comfortable during short heating steps. Keep the clamp out of the direct flame and store it dry.
Who supplies the Test Tube Clamp?
The clamp is a supplied item from Science Lab Supplies, an Ambala, India business that can put it on one quotation with other chemistry lab items for schools, colleges, distributors and tender contractors.
Can you quote clamps for a whole school laboratory?
Yes. Send the number of clamps and any other items you need, with the delivery location, and a single quotation will cover the complete list.
