Its ability to selectively diffuse molecules across a semi-permeable membrane gives dialysis tubing its important place in classic laboratory technique. Dialysis is used for a wide variety of dialysis applications: desalting, buffer exchange, removal of labeling reagents, drug-binding studies, cell growth and feeding, virus purification, and blood treatment. Created from a natural source of cellulose, dialysis tubing provides a reliable source for separating molecules based on size for testing purposes, and no pre-treatment is required before use. Regenerated cellulose dialysis tubing is also available.
