Applications and Experiments for the Brass Test Tube Clamp
These clamps hold a test tube securely while it is warmed over a flame, shaken, or carried to a rack. Despite the wooden handle in its name, each holder is solid brass throughout, with flat handle strips for the grip. They suit CBSE and NCERT science classes, Class 11–12 salt analysis and B.Sc. laboratory courses.
- Class 10 science: heating solids for decomposition reactions over an Adjustable Bunsen Gas Burner with Control Valve (Set of 2).
- Class 11–12 salt analysis: dry-heating and gas tests, with eyes protected by Safety Glasses.
- Biology food tests: lifting tubes out of a boiling water bath after the Benedict’s test.
- Gentle heating of small samples on a Brass Spirit Lamp 100ml where no gas line is available.

Frequently Asked Questions
What size test tubes do these clamps hold?
They grip tubes from 12 mm to 25 mm outer diameter. The self-closing spring brings the jaws together by itself, so nothing needs adjusting when a student moves from one tube size to another.
Who supplies the Wooden Handle Brass Test Tube Clamp (Set of 12)?
The set is quoted and dispatched by Science Lab Supplies, Ambala, India. Share the number of sets and the delivery address, and the reply covers packing, delivery time and price in one document for schools, colleges, dealers or contractors.
Can the clamp be held in a burner flame?
The brass jaws tolerate brief flame contact without losing spring tension, and the 160 mm length keeps the hand at a distance. Grip the tube about a third of the way below the rim, heat gently and work under teacher supervision.
How should the clamps be looked after?
Rinse them with clean water and mild soap after contact with acid fumes or spills, dry them fully, and put one drop of light machine oil on the pivot once a year to keep the spring action smooth.
