Pinch Clip
Pinch Clip (Product Code: SLE/CH/67) is a small clip that squeezes a length of flexible laboratory tubing flat, stopping the flow of liquid or gas through it until the clip is released. It works as a simple on/off valve on rubber or silicone tubing in burettes, siphons and gas apparatus. The clip is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for school and college chemistry labs that build their own gas collection apparatus in India and international markets.
Key Details
| Parameter | Detail |
|---|---|
| Type | Clip for flexible laboratory tubing |
| Purpose | Closing off rubber or silicone tubing to stop liquid or gas flow |
| Suitable for | Burettes fitted with rubber tubing and a glass jet, siphons, gas delivery and collection set-ups |
| Supplied as | Individual clips; material, size and pack quantity confirmed on enquiry |
Typical Use
On a simple burette made from a glass tube, a short piece of rubber tubing and a jet, the pinch clip takes the place of a stopcock: pressing it opens the tubing and lets titrant run, releasing it shuts the flow. In gas preparation, a clip on the delivery tubing holds the gas back while a gas jar is positioned, and it can seal off a side arm or siphon line when the apparatus is being dismantled.
A pinch clip gives quick on/off control. Where a steady, adjustable drip is needed, a screw clip is the better choice. Fit the clip on a straight, undamaged section of tubing, and move it slightly now and then so the rubber does not take a permanent crease. These clips are small and easily lost, so labs usually keep spares with their chemistry lab equipment consumables.

Tubing and apparatus that a pinch clip is normally used on:
- Rubber Tubing — the flexible tubing the clip closes
- Silicone Tube — an alternative tubing that also takes the clip
- Hoffman Screw Clip — for gradual, adjustable flow control
- Delivery Tube — carries gas to the collecting vessel
- Gas Jar, Glass — collects the gas released through the tubing

Frequently Asked Questions
What tubing size does the clip fit?
We do not list a tubing size on this page. Send us the outer diameter and wall thickness of your tubing through the contact page and we will confirm a suitable clip.
How is a pinch clip different from a Hoffman screw clip?
A pinch clip is an open/shut control. A Hoffman screw clip closes the tubing progressively with a screw, so the flow rate can be set.
Is tubing included?
No, the clip is supplied on its own. Rubber or silicone tubing can be added to the same order.
Can it replace a burette stopcock?
On a rubber-tube burette, yes — that is one of its classic uses. Glass burettes with a built-in stopcock do not need it.
What is it made of, and are colours available?
Material and finish options are confirmed at the time of quotation; please ask if you have a specific requirement.
Can you supply clips in larger quantities?
Yes. We supply schools, colleges and distributors in India and international markets.
