4 DIALYSIS TUBING IAlso known as Visking tubing, for use in osmosis, diffusion, and filtration experiments. These semi-permeable (selectively permeable) membrane tubes are made from reformed cellulose and are supplied in a range of different diameters. The Molecular Weight Cut Off (MWCO) of the Visking / Dialysis tubing supplied is 12000-14000 Daltons, which should allow glucose molecules to pass through. Before use, wash the tubing and rinse in warm water. As the tubing is open ended, tubing clips offer a useful means of sealing the ends. Cat No. Int.
