Cellulose Acetate (CA) membranes are a mixture of cellulose triacetate and diacetate creating a strong membrane in both lateral and longitudinal directions. Compared to MCE membrane, CA exhibits improved solvent resistance to low molecular weight alcohols, improved heat resistance up to 180˚C, and may be repeatedly autoclaved or steam-sterilized without loss of integrity.
These membranes have a very low static charge which can minimize particle contamination of the membrane. This characteristic makes CA membrane idealy suited for OEM applications. Recovery of fastidious gram+ organisms may be enhanced by culturing on CA membrane. CA membranes are low protein binding and have low aqueous extractables(0.1%wt).
Typical applications include filtration of enzyme solutions to minimize protein loss, diagnostice cytology, receptor binding studies, and filtration of solutions containing alcohol.
