Micro filtration membrane (M) series
M series membrane can be divided into mixed cellulose, nylon-6, nylon-66, PES, PVDF, PTFE, PP type according to material.
Mixed cellulose micro membrane
A polymer film filter, mixed by nitrocelluolose and cellulose acetate. Pore extreme development, Effective porosity of up to 80%. Uniform aperture, small resistance, high flow speed, little absorption, no media loss during filtration.
Nylon-6, Nylon-66 microfiltration membrane
Representative aliphatic polyamide filter, with natural hydrophilic, positive charge. Pore development, pore forming with mesh, has excellent resistance to organic solvents, acid, alkali, heat. Meantime with high mechanical strength.
PES Microporous membrane
Sulfonated treatment to polymer polyethersulfone resin, bring in sulfonic acid gene. This membrane has good chemical compatibility, protein absorption rate lower than nylon. With high filtration precision, it is a safe sterile cartridge. Effective operture openins, high flux. Typical asymmetric pore structure, strong fouling resistance.
PVDF Microporous membrane
Fluorine type filter material. With natural hydrophobic, protein absorption rate is very low, excellent heat and chemical resistance, tolerated acid, aliphatic, aromatic vinyl alcohol, aldehydes, ketones and other organic and inorganic solvents. Can be used for both steam and liquid sterile filtration. High porosity, asymmetric pore structure, high pollutant capacity. Can be changed to hydrophilic membrane, used for solid and sterile filtration of high surface tension water based liquid.
PTFE Microporous membrane
Fluorine type filter material, with natural strong hydrophobic. Excellent heat resistance and widely chemical compatibility, bidirectional stretched into hole. Extremely development pore, It is an excellent steam sterile filter, also suitable for high corrosion, strong oxidizing organic solvent and inorganic solvent. With low gas resistance, high flux, it can be changed into hydrophilic membrane, used for solid and sterile filtration of high surface tension water base liquid.
