Visking Tubing Clips
Visking Tubing Clips (Product Code: SLE/BL/058) are single-size plastic clips used to seal the ends of dialysis membrane tubing for osmosis, diffusion and dialysis work in school, college and research laboratories. They suit most situations where membranes of up to 40mm flat width are used (to Size 7), are reusable and autoclavable, and come in a pack of 10. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a practical part of an osmosis experiment kit for schools.

What Are Visking Tubing Clips Used For?
The classic use is making a sealed membrane bag for osmosis and diffusion experiments. Students soak a length of visking tubing until it softens, fold over one end and close it with a clip, fill the bag with a sugar or starch solution, then fold and clip the other end. The bag is placed in a beaker of water or a different solution, and changes in mass, volume or colour show which molecules have passed through the membrane — a simple model of a cell membrane or of absorption in the gut.
The same approach works for dialysis demonstrations in chemistry and for separating small molecules from large ones in introductory biochemistry, so the clips earn a place among cell biology equipment in India's teaching labs. For a leak-free seal, fold the tubing end neatly before clipping and check the bag over a sink before immersing it. After the practical, rinse the clips, autoclave them if your lab requires it, and store the full pack together for the next class.
Supplier
Visking Tubing Clips are supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab in Ambala, Haryana, India, and equips laboratories in India and international markets. The clips can be quoted together with dialysis tubing and beakers, so a membrane practical is covered by one order. The company profile describes the business in more detail.

- Visualising Osmosis & Diffusion Investigation — a structured investigation built around the same principles
- Osmosis Simulation Activity Model — helps students picture what happens at the membrane

Frequently Asked Questions
Which tubing sizes do Visking Tubing Clips fit?
Visking Tubing Clips are a single size designed for membranes of up to 40mm flat width (to Size 7), which covers most dialysis tubing used in teaching labs, so one pack serves several tubing sizes without separate clips for each.
How many clips are in a pack?
Each pack of Visking Tubing Clips contains 10 clips. Because a sealed membrane bag needs one clip at each end, a single pack closes up to five bags at the same time, enough for several groups in one osmosis practical.
What are the dimensions of Visking Tubing Clips?
Each of the Visking Tubing Clips has an overall length of 53mm when closed, a width of 11mm and a thickness of 6mm, a compact size that lets a filled tubing bag sit in a beaker without the clip getting in the way.
Can Visking Tubing Clips be autoclaved and reused?
Yes. Visking Tubing Clips are reusable and autoclavable, so they can be rinsed, autoclaved where your laboratory requires it, and used again, rather than being thrown away after each osmosis or dialysis practical.
Will the clips fit the Visking Tubing you supply?
Yes. The Visking Tubing, 30m that we supply has a flat width within the limit these Visking Tubing Clips are designed for, so the clips and tubing can be ordered together for membrane experiments.
Who supplies Visking Tubing Clips?
Visking Tubing Clips are supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. Colleges, schools and distributors in India and international markets can order several packs, with or without tubing, on one quotation.
