This material is aliphatic nylon with good hydrophilicity. It is not only suitable for acidic or alkaline aqueous solution, but also organic solvents, such as alcohols, hydrocarbons, ethers, esters, ketones, benzene and benzene homologues, dimethyl formamide, dimethyl sulfoxide, etc. It is one of the most widely used microporous filter membrane.(terminal filter membrane)
The pore size selection principle is same to mixed cellulose membrane, which is using nominal diameter um in particle filter, in sterilization using nominal pore size 0.65um, 0.45um, 0.3um, 0.22um, 0.1um, Diameter: 100mm, 150mm, 200mm, 300mm, 400mm.
Factory set technical standards are as follows:
Nominal pore size (µm) |
Water flow ml/cm2. min |
Porosity % |
Bubble point pressure range (mPa) |
Membrane thickness (mu) |
Membrane morphology (flat) |
