PTFE sterilizing filter membrane resistant to strong acids and alkalis, It is gentle to ozone, has wide chemical compatibility, and has good biological reliability. No fibers will fall off when washed with high-purity water. It can withstand strong solvents such as DMSO, THF, DMF, methylene chloride, and chloroform. There are two types: hydrophilic and hydrophobic.
Used in steam dust removal and sterilization filtration; sterile packaging air filtration; mineral water and purified water resistant to ozone and other strong oxidants Liquid filtration; filtration of all organic solutions, especially filtration of strong solvents that other filter membranes cannot tolerate; suitable for clarification filtration of hydrophilic strong acids and strong bases, filtration of high-temperature liquids, and filtration of special chemical reagents.
Sterilization filtration: refers to the process of removing all microorganisms in the fluid. The accuracy generally does not exceed 0.22um or 0.2 Um. Due to the lack of a unified standard in the industry to measure pore size, the nominal pore size has no practical significance for predicting the retention of microorganisms. Therefore, it is necessary to use microbial retention capacity to define sterilizing grade filters.
The PTFE sterilizing filter membrane currently developed and produced by ourselves is a good choice for sterilizing filtration, with pore sizes of 0.1 micron, 0.22 micron, Different pore sizes such as 0.45 micron, 1 micron, and 3 micron have controllable precision, uniform distribution, and excellent chemical properties, reaching HIMA standards. The membrane pore size is adjustable to obtain different bubble point pressures to meet different filtration precisions. PTFE sterilizing filter membrane has two categories: hydrophobic and hydrophilic. After integrity testing, it can be used for liquid filtration without bacterial cells. After being hydrophilic, it performs well in water filtration applications. It is widely used in strong corrosive solvents, infusion filtration, leukocyte filtration, tissue culture and many other fields. Interested parties can enter the store and contact us.
