Dialysis Tubing 46/28mm – 5m Roll

This dialysis tubing, also referred to as visking tubing or dialysis membrane, is made from a semi-permeable cellulose membrane, ideal for demonstrating osmosis, diffusion, and separation of substances in laboratory experiments. The membrane allows selective passage of particles with molecular weights between 8,000 and 14,000, making it a reliable choice for biology and chemistry studies.

Supplied in a 5m roll, this tubing can be cut to the desired length for flexible use in classroom or laboratory activities. With a flat width of 46mm (28mm diameter when inflated), it is suitable for a wide range of practical applications.
