Membrane Selection Guide
|Membrane Type||Available Sizes||Description|
|Regenerated Cellulose||1 to 50 kDa MWCO||The regenerated cellulose membranes are more stable in organic solvents than other
types of membranes and are low protein binding. Ready to use after rinsing with deionized
water and buffer. Glycerol, sulfur, and heavy metals are not present in these membranes.
|Cellulose Acetate||500 Da to 300 kDa MWCO||These membranes are low protein binding and have a sharp MWCO range. Supplied in
0.05% sodium azide solution and ready to use after rinsing with deionized water and buffer.
Glycerol, sµlfur, and heavy metals are not present in these membranes. Intended only for
aqueous solutions, and the presence of an organic solvent is not recommended.
|Polycarbonate||0.01 µm – 0.60 µm Pore Sizes
||Polycarbonate membranes are chemically resistant and are ideal for use with acids and
organic solvents. Shipped dry and must be rehydrated before use.
