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.
The Advantage of Cellulose Acetate Filter Is
Cellulose acetate membrane is ISO9001 approved Low static charge and high strength Various pore sizes and diameters available Good performance with fast filtration speed
Features of Cellulose Acetate Filter
Hydrophilic membrane filter Sterile and Non-sterile are all available Both round disc and roll types are available. Limited solvent resistance Low extractable to ensures tests clean with consistent results Resistance to low molecular weight alcohols, hydrocarbons, and oils
Applications of Cellulose Acetate Membrane Filters
Filtration of protein and enzyme Filtration of buffers, aqueous reagents, and EIA/ELISA reagents and samples. Recovery of protein Diagnostic cytology Sterilization of tissue culture media Tissue culture media sterilization Used for biological and clinical analysis, MCE gridded membrane filter can also be used for
