Seamless cellulose membranes featuring sharp Molecular Weight Cut-Offs in both tubing and flat sheets. Dialysis membranes are made of regenerated cellulose using the viscose process. These semi-permeable membranes have distinct Molecular Weight Cut-Off (MWCOs) of 14,000, 7,000 and 3,500 daltons by excluding macromolecules with molecular radii from 50 down to 35 angstroms.

Features:

1. Excellent pH and chemical stability, the membranes are stable in weak acids and bases
2. Great compatibility with many salts –CaCl2 , (NH4 )2 SO4 , etc.
3. Excellent compatibility with most aqueous organic solvents, such as alcohols and ketones
4. Excellent temperature resistance
5. Contains low levels of contaminants, some membranes contain glycerin as a humectant, contaminants may be removed by boiling prior to use
