Membranes for ElectroPrep dialysis chambers are available in three membrane materials to suit your application: regenerated cellulose, cellulose acetate, and polycarbonate. Membranes are 15/16" in diameter and pre-cut to fit ElectroPrep dialysis chamber sizes. Membranes ship dry to increase their shelf life, and must be rehydrated before use.

• Regenerated cellulose: constructed of a very stable cellulose, regenerated cellulose membranes are resistant to solvents. This membrane is inert to proteins providing maximum sample retention. These membranes are available in MWCO’s from 1 to 50 kDa with pore sizes that are less defined than the cellulose acetate membranes.
• Cellulose acetate: cellulose acetate membranes are made of rayon and are ideal for use with aqueous solutions. They are not meant for use with any organic solvents. These membranes are inert to proteins providing high sample retention. These membranes are available in MWCOs from 500 Da to 300 kDa and have a more defined pore size than the regenerated cellulose membranes.
• Polycarbonate: chemically resistant and are ideal for use with acids and organic solvents. These membranes are available with sharply defined pore sizes ranging from 0.01 to 0.60µm.
