Surfactant-free Cellulose Acetate (SFCA) Membrane

SFCA membrane Surfactant-free cellulose acetate (SFCA) is a good choice for all aqueous solutions. Without surfactant or wetting agents as compared to standard CA membranes, it features very low extractables and leachables. Free of active surface agents, makes it low absorption characteristic, thus SFCA is a perfect choice for biologic solutions like serum and cell culture media. In some high protein fluid samples , SFCA may even flow faster than PES membrane.

Cobetter SFCA membrane is available in roll format as well as in sheets and disks that can be customized to meet your application and size requirements.
