Cellulose acetate (CA) membranes exhibit low protein binding capacity, high thermal stability and high physical strength.
These properties make CA membranes suitable for the high-pressure filtration of aqueous and alcoholic media.

Heat stability – Maintains integrity after autoclaving – 121 °C for 30 minutes
Non-sterile membranes – Autoclavable for 30 minutes at 121 °C
Sterile membranes – Sterilized by Ethylene Oxide (EO)
Non-sterile membranes – Bulk-packed 100 membranes per box
