Product Code : SCL-CL-11562
Elastic Clamp for Rubber Pipes (Mohr Clamp) (SKU SCL-CL-11562) is an elastic 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 serves school and college chemistry benches wherever tubing must be closed. The clamp is available from Science Lab Supplies in Ambala, India, which prepares quotations for institutions, distributors and project buyers.
Specifications
Five facts define the Mohr clamp, and the table below gives each one. In short, it is an elastic clamp for rubber pipes made of chemical-resistant steel in a silver colour, and its jaws accept tubing up to a maximum space of 16 mm, keeping the tube pinched closed until the grips are squeezed.

Applications and Experiments for the Mohr Clamp
A Mohr clamp closes rubber tubing quickly: squeeze it and the tube opens, release it and flow stops. It can be fitted to gas-delivery tubes, siphons and rubber-tube burette outlets, making it practical chemistry lab equipment in India for secondary and undergraduate experiments where simple on-off control is enough.
- Class 10–12 chemistry: shutting off delivery tubes while collecting gases from a Kipps Apparatus.
- Titration practice: closing rubber-tube burette outlets fitted with a glass jet.
- Biology and physics labs: sealing tubing joined to Glass Tubes of Different Diameters on respirometers, manometers and siphon demonstrations.
Where gradual control of flow is needed, a screw-type Hoffman clamp can be used instead; 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 silver steel clamp with a 16 mm maximum space. Rubber tubing and glassware are ordered separately, and any optional accessories you request are shown on the quotation alongside the clamp.
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, stoppers and burettes on it too so the set-up arrives in one consignment.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Zambia, Rwanda, South Africa, Qatar, Sri Lanka and Vietnam. Mohr clamps can be added to the enquiry cart in any quantity; the contact page takes technical questions and the lab tender page covers tender paperwork.
Frequently Asked Questions
What is a Mohr clamp used for?
It pinches rubber tubing closed to stop liquid or gas, and squeezing the grips opens it again. It can be used on delivery tubes, siphons and rubber-tube burette outlets.
What tubing size does it take?
The clamp opens to a maximum space of 16 mm. Check the outside diameter of your rubber tubing against this figure, and name the tubing in your enquiry if you are unsure.
Who supplies the Elastic Clamp for Rubber Pipes (Mohr Clamp)?
Quotes for this clamp are issued by Science Lab Supplies, and goods leave from Ambala, India. Single packs for a school and larger lots for distributors or tender contractors receive the same itemised quotation.
Is the clamp suitable for chemistry rooms?
Yes. It is made of chemical-resistant steel, so it can be used on tubing in a chemistry laboratory where acid fumes and splashes are present; rinse and dry it after contact with reagents.
