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
