Separation and purification are widely used in various industries, due to different sample matrices and states. There are also some tips for selecting filter materials. Either the most expensive filter membrane is the most expensive one. Only the one suitable for the application is the best choice. Here, the editor recommends Teflon liquid filtration membrane to everyone.
For sterilizing filters, all manufacturers have a common standard, which is 0.22 microns, which is also a requirement of regulations. Generally, we will add a first-level pre-filter before the sterilizing filter. The function of this pre-filter may be to reduce the microbial load, clarify the medicinal solution, or it may be to filter some large particles and impurities, etc. , reduce the pressure on the sterilizing filter. For this pre-filter, each manufacturer’s calibration materials, retained materials, and operating conditions are different, and there is no recognized standard.
The porosity of Teflon liquid filter membrane can reach 80%~90%, and it has been heat-set at high temperature. Its microporous structure is stable and can effectively intercept dust particles. Its pore size is small and uniform, and its surface is The filtration mechanism allows for easy dust removal, strong hydrophobicity, and low surface energy, which ensures complete retention of bacteria and other impurities while having a large flux. When used for gas filtration, it can achieve 100% interception of various phages, bacteria and particles above 0.02um.
