Elastic Clamps for Rubber Pipes (Mohr Clamp)
Elastic Clamps for Rubber Pipes (Mohr Clamp) (Product Code: SCI-759/033) is a steel spring pinch clamp used to squeeze rubber tubing shut, or release it, to stop and start the flow of liquid or gas in laboratory apparatus. It takes tubing within a maximum space of 16 mm, and its chemical-resistant silver steel suits wet bench work as everyday chemistry lab equipment in India. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Mohr Clamp Used For?
The Mohr clamp is the on-off switch of rubber tubing. It closes the rubber outlet of a burette or dropping set-up that uses a tube instead of a stopcock, shuts a gas delivery line while one full gas jar is exchanged for an empty one, and holds a siphon closed until the receiving vessel is in place. Pressing the clamp opens the jaws and releasing it lets the spring close them again, so a single hand controls the flow.
Fit the clamp on a straight length of tubing, well away from glass joints, so the pinch does not strain the connection. Where a partial, steady flow is needed, pair it with a Hoffman screw clamp, which closes by degrees. Remove the clamp from tubing that is being stored, otherwise the rubber takes a permanent crease, and rinse and dry the steel after it has been splashed with chemicals.
OEM Manufacturer
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer of these Mohr clamps and makes them at its own licensed factory in Saha, Ambala, Haryana, India. Schools and colleges, as well as dealers and importers, buy them straight from the factory, so extra clamps for new benches or replacements for lost ones are quoted by the maker — just ask us. See the ScienceLab company profile for background.

Frequently Asked Questions
What does the Mohr clamp do?
Elastic Clamps for Rubber Pipes (Mohr Clamp) pinch rubber tubing shut to stop the flow of liquid or gas, and open it again when the clamp is pressed. It is a quick on-off clamp for burette outlets, siphons and gas delivery lines in laboratory set-ups.
What tubing size does it take?
Elastic Clamps for Rubber Pipes (Mohr Clamp) have a maximum space of 16 mm between the jaws, so they suit rubber tubing that fits within that opening. If you are unsure about a particular tube, send us its outer diameter through the contact page.
How is a Mohr clamp different from a Hoffman clamp?
The Mohr clamp is a spring-type on-off clamp, while a Hoffman clamp uses a screw to squeeze tubing gradually. Choose Elastic Clamps for Rubber Pipes (Mohr Clamp) for fast shut-off, and a Hoffman screw clamp when you need to set a partial, adjustable flow.
Who manufactures the Mohr clamp?
Elastic Clamps for Rubber Pipes (Mohr Clamp) are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers order them factory-direct and receive quotations from the maker.
How should the clamps be cared for?
Rinse Elastic Clamps for Rubber Pipes (Mohr Clamp) with water after chemical splashes and dry them before storage; the steel is chemical resistant, but clean, dry clamps keep their spring action longer. Take the clamp off tubing that is not in use.
Can they be ordered in bulk?
Yes, Elastic Clamps for Rubber Pipes (Mohr Clamp) can be ordered in small or bulk quantities for schools, colleges, dealers and importers in India and international markets. List the quantity, delivery location and any tubing needed on the contact page for a manufacturer's quotation.
