3. Mixed cellulose ester filter membrane
Features: relatively uniform pore size, high porosity, no medium shedding, thin texture, small resistance, fast filtration speed, minimal adsorption, low cost of use, but not resistant to organic solutions and strong acid and alkali solutions.
Uses: The pharmaceutical industry needs autoclaved water injection to filter out particles during large infusion; the sterilization of heat-sensitive drugs; analysis and determination of particulates and oil insoluble in solution, and determination of water pollution index. It is also applied to scientific research departments such as somatic hybridization and mitochondrial prediction of heterosis.
4. Polypropylene filter membrane
Features: No adhesive, stable chemical properties, flexible, not easy to break, high-temperature resistance, which can withstand high-pressure sterilization, non-toxic and tasteless, acid and alkali resistant.
Uses: Used in the fields of medicine, chemical industry, food, beverage, etc.
5. PES filter membrane
Features: The microporous membrane made of ether sulfone is a hydrophilic membrane, with a high flow rate, low leachable, and good strength. It does not adsorb proteins and extracts and pollutes the sample.
Uses: Low protein adsorption and high drug compatibility, specially designed for biochemical, inspection, pharmaceutical, and sterilization filtration devices.
6. PTFE filter membrane
Features: The most extensive chemical compatibility, which can withstand strong solvents such as DMSO, THF tetrahydrofuran, DMF dimethylformamide, dichloromethane, and chloroform.
Application: Filtration of all organic solutions, especially the filtration of strong solvents that other filter membranes cannot tolerate.
