Description

Description of Cellulose Acetate membrane

Cellulose acetate membrane filters (CA) are a kind of hydrophilic membrane with very low protein binding capacity but excellent throughout the capacity. Cellulose acetate membrane is naturally hydrophilic, suitable for aqueous solution processing, low protein adhesion.

Cellulose acetate filter has the characteristics of high flow rate, strong thermal stability, low adsorption, suitable for positive pressure filtration, hydrophilic good performance, uniform pore structure and high flow rate, suitable for pH 3.5 – 8 aqueous solutions or other organic solvents such as oils, ethanol, etc., 0.22 μm CA filter membrane is an ideal membrane for sterilizing and filtering aqueous solutions such as buffers, serum, culture media, wide aperture range. Cellulose acetate membrane filter, like PES membrane, are commonly used filters in biology. Compared to MCE membrane filter, CA filter membrane has improved solvent resistance to low molecular weight alcohols, better heat resistance, and reduced protein binding.
