Membranes for Dialysers
A large variety of membranes are available for use with our products. The following tables are designed to assist you in choosing the appropriate membranes for your needs.
Regenerated Cellulose. These membranes are more stable in organic solvents, but the MWCO range is not as sharply defined as that of cellulose acetate membranes. The membranes are pre-cut, and supplied in a 0.05% sodium azide solution. They are ready to use after rinsing with deionized water and buffer. Glycerol, sulfur, or heavy metals are not present in these membranes.
Polycarbonate. These membranes are more stable in organic solvents. They are available in four highly controlled pore sizes for a well defined MWCO range.
Cellulose Acetate. These membranes are low protein binding and have a sharp MWCO range. The membranes are pre-cut, and supplied in 0.05% sodium azide solution. They are ready to use after rinsing with deionized water and buffer. Glycerol, sulphur, and heavy metals are not present in these membranes. The cellulose acetate membranes are intended only for aqueous solutions, and the presence of an organic solvent is not recommended.
