Test Tube Holder (Peg Type) Manufacturer,Supplier and Exporter in India

Test Tube Holder (Peg Type) (Product Code: SLE/CH/230) is a wooden holder built like a large clothes peg: a spring keeps its jaws closed on a test tube, so a student can hold the tube over a flame without gripping the hot glass. At 180mm long it keeps the hand a safe distance from the burner during heating and flame tests, and it accepts tubes from 11 to 19mm in diameter. The holder is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and is one of the most frequently used items of school chemistry lab equipment in India.

Specifications

Typical Use

The peg-type holder is the everyday choice for heating small quantities of solid or liquid in a standard test tube — decomposing a carbonate to test for carbon dioxide, warming a food sample with a reagent, or driving water out of a hydrated salt. Students squeeze the peg, slide the tube in near its mouth and let go; the spring then holds the tube on its own, leaving the other hand free for the burner or a gas test. Because wood is a poor conductor of heat, the holder stays comfortable in the hand even after several minutes over the flame.

Hold the tube at a slant, point the open end away from everyone, and move it gently through the flame so the contents heat evenly. Keep the wooden jaws above the flame rather than in it, since wood can scorch. The 11–19mm range covers the narrower tubes used in most school practicals; for wider tubes, choose the metal holder listed below. Having one holder per student is a simple step in any school laboratory setup that reduces burns and dropped glassware.

Frequently Asked Questions

Which test tube sizes does it hold?
Tubes of 11–19mm diameter. Tubes outside that range will either slip or will not open the jaws far enough.

How long is the holder, and what is it made of?
It is 180mm long and made of wood, with a spring that closes the jaws.

Can it be used for boiling tubes?
Only if the tube's outside diameter is within 11–19mm. Wider boiling tubes need the metal test tube holder.

Will the wood burn?
Wood can scorch if the jaws are pushed into the flame. Heat the lower part of the tube only and keep the holder above the flame, and it will last for many practicals.

Is it suitable for younger students?
Yes, it is widely used in secondary school practicals under supervision. The spring grip means students do not need to squeeze continuously to hold the tube.
