Product Code : SCL-CL-12012
Wooden Handle Brass Test Tube Clamp (Set of 12) (SKU SCL-CL-12012) is a pack of twelve spring-loaded holders for gripping glass test tubes while they are heated, shaken or lifted out of a water bath. Students and laboratory assistants use them in school science practicals and college chemistry labs. The set is supplied by Science Lab Supplies from Ambala, India, to schools, colleges, tender contractors and distributors buying school chemistry lab equipment in India.
Specifications
Each holder is formed from solid brass strip with a self-closing spring action and a riveted spring-steel pivot, so it closes on the tube without an adjusting screw. Finger pads open the jaws, the grip end carries the wooden handle named in the title, and the 160 mm length keeps the hand away from the flame.

Frequently Asked Questions
What size test tubes do these clamps hold?
They grip tubes from 12 mm to 25 mm outer diameter, the usual sizes in school and college chemistry. The spring closes the jaws by itself, so nothing needs adjusting between sizes.
Who supplies the Wooden Handle Brass Test Tube Clamp (Set of 12)?
Science Lab Supplies, based in Ambala, India, supplies this set to schools, colleges, dealers and tender contractors. Send your quantity and delivery address and the quotation comes straight from the Ambala office.
Can the clamp be held in a burner flame?
The brass jaws tolerate brief flame contact and the 160 mm length keeps the hand at a distance. Heat gently all the same, point the tube away from people and let students work under teacher supervision.
