Visking Tubing for Dialysis new Cotrimoxazole 25µgA high quality cellulose based, selectively permeable material, in tube form, which can be used to demonstrate osmosis and dialysis separation techniques.

This is a great demonstration mimicking the small intestine. Molecular weight cut off (MWCO) 12 14000 dalton 5m
