Description
Ideal for molecular separation, protein binding studies, electrolyte removal, desalting
Supplied as flat-width tubing or flat sheets that can be folded to fit various funnel-type dialysis apparatus. Pure regenerated natural cellulose membranes with 1000 to 50,000 molecular weight cutoffs.
- Transparent and flexible
- Low molecular weight compounds in aqueous solutions diffuse through membrane
- Higher molecular weights, such as proteins and bacteria, are retained by membrane
- Glycerol preserves membrane and must be removed before use
- Flat sheets and discs available for use with dialysis apparatus
Do not tie knots in tubing; use closures
