CA Membrane, CA, 0.45 μm (CAT#: STEM-BC-0126-ZJF)

The CA membrane is a cellulose acetate membrane designed for aqueous sample filtration. It has natural hydrophilicity and is suitable for water-based processing. The membrane provides very low protein adsorption to support high product recovery. Its smooth surface, high open area, and uniform pore structure support stable filtration. It is suitable for removing particles and bacteria from biological samples and water-soluble samples. It can also be used for solvent filtration, mixture filtration, clarification, and filtration of high-protein liquids. The membrane provides good biocompatibility and thermal stability. Roll and sheet formats can be provided with customizable dimensions.
