When developing analytical methods such as dissolution experiments and content of preparation samples, due to the influence of excipients, filtration is required and the continued filtrate is used as the test solution.
In the filtration process, a ptfe sterilizing filter membrane is required.
The material and type of filter membrane sometimes have a relatively large impact on the sample, and different filter membranes need to be screened.
PTFE medical mask filter material can ensure complete interception of impurities such as bacteria and has a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
