Visking Tubing, 30m
Visking Tubing, 30m (Product Code: SLE/BL/059) is a seamless viscose cellulose dialysis membrane used to separate small molecules from large ones in osmosis, model-gut and dialysis experiments in school, college and research laboratories. It has a flat width of 25mm (Size 2) and a molecular weight cut-off of 12000–14000, and it is supplied flat packed on a reel. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as cell biology equipment in India.

What Is Visking Tubing Used For?
In school biology the tubing is widely used as a model gut. Students fill a length with a mixture of starch and the enzyme amylase, close both ends, and stand it in warm water. Testing the surrounding water over time shows that sugar produced by digestion passes through the membrane while the undigested starch stays inside — a clear link between digestion and absorption that makes it a staple companion to an enzyme experiment kit in school. The same tubing is used for osmosis work, where a bag of sugar solution gains mass as water moves in.
In college and research labs, the 12000–14000 cut-off makes it useful for dialysis, such as removing salts or small molecules from a protein sample. Cut only the length you need from the reel, soak it in water until it softens, and rub the end between your fingers to open the seamless tube. Close the ends with knots or clips, and handle the membrane with clean gloves so it is not contaminated.

Frequently Asked Questions
What does the molecular weight cut-off of Visking Tubing, 30m mean?
A molecular weight cut-off of 12000–14000 means Visking Tubing, 30m retains molecules much larger than that size, such as starch and most proteins, while water, salts, sugars and other small molecules can pass through the membrane.
How wide is Visking Tubing, 30m?
Visking Tubing, 30m has a flat width of 25mm and is designated Size 2. Once softened and opened, the seamless tube forms a narrow membrane bag that suits beaker-scale osmosis and model-gut experiments in teaching laboratories.
How is Visking Tubing, 30m packed?
Visking Tubing, 30m is supplied as a single 30m length, flat packed on a reel, so a technician can cut exactly the length each practical needs and keep the rest of the reel sealed and clean for later classes.
How is the tubing prepared before use?
Before use, soak a cut piece of Visking Tubing, 30m in water until it softens, then rub the end between your fingers to open the seamless tube. For research dialysis, follow your laboratory's own membrane preparation procedure.
How are the ends of the tubing sealed?
The ends of Visking Tubing, 30m can be closed by tying a knot in the softened membrane or by using Visking Tubing Clips, which are reusable and designed for this range of flat widths.
How should a reel of Visking Tubing, 30m be stored?
Store the Visking Tubing, 30m reel dry, sealed and away from heat and dust, and handle the membrane with clean hands or gloves when cutting pieces so the surface is not contaminated before an experiment.
Who supplies Visking Tubing, 30m?
Visking Tubing, 30m is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. The company serves laboratories in India and international markets and can quote several reels together with tubing clips.
