Product Code : SCL-CL-11562
Elastic Clamp for Rubber Pipes (Mohr Clamp) (SKU SCL-CL-11562) is a spring steel pinchcock that presses rubber tubing shut to stop the flow of liquid or gas. It opens to a maximum space of 16 mm and is a standard small item on school and college chemistry benches. Science Lab Supplies ships it out of Ambala, India to schools, colleges, training institutes, tender contractors and distributors that order it.
Specifications
The Mohr clamp is made of chemical-resistant steel in a silver colour. Its elastic, spring action keeps rubber tubing pinched closed until the grips are squeezed, and the jaws accept tubing up to a maximum space of 16 mm.

Applications and Experiments for the Mohr Clamp
A Mohr clamp is used to close rubber tubing quickly: squeeze it and the tube opens, release it and flow stops. Teachers use it on gas-delivery tubes, siphons and simple burette outlets, making it a routine part of chemistry lab equipment in India for secondary and undergraduate practicals.
- Class 10–12 chemistry: shutting off delivery tubes while collecting gases.
- Titration practice: closing rubber-tube burette outlets fitted with a glass jet.
- Biology and physics labs: sealing tubing on respirometers, manometers and siphon demonstrations.
For gradual control of flow a screw-type Hoffman clamp is usually chosen; the Mohr clamp suits simple open-or-closed use.
Standard Scope of Supply
The Elastic Clamp for Rubber Pipes (Mohr Clamp) is supplied as a single steel clamp as described above. Rubber tubing and glassware are ordered separately, and any optional accessories are listed on the quotation.
Packing, MOQ and Lead Time
Clamps can be quoted singly, by the dozen or as a complete class set. Every quotation spells out packing, delivery time and price for the quantity you name, and you can put tubing and stoppers on it too.

Frequently Asked Questions
What is a Mohr clamp used for?
It pinches rubber tubing closed to stop liquid or gas; squeezing the grips opens it again. It is used on delivery tubes, siphons and burette outlets.
What tubing size does it take?
The clamp opens to a maximum space of 16 mm, enough for the rubber tubing used in school and college laboratories.
Who supplies the Elastic Clamp for Rubber Pipes (Mohr Clamp)?
Science Lab Supplies supplies it from Ambala, India, quoting single packs for schools as well as larger lots for distributors and tenders.
Is the clamp suitable for chemistry rooms?
Yes. It is made of steel described as chemical resistant, so it tolerates the conditions of a normal chemistry laboratory.
Related Tubing Accessories
The Mohr clamp is one part of a tubing set-up. A screw clamp for finer control, the tubing itself, bored stoppers and burettes complete the practical, and all of them can be listed on one quotation with the clamp.
- Screw Pipe Clamp (Hoffman Clamp) — screw clamp for gradual flow control.
- Rubber Tube (Laboratory) — tubing for the clamp to close.
- Rubber Stoppers of Various Diameters with Holes — join tubing to flasks.
- Burette — titration glassware used alongside tubing clamps.
