Precautions and maintenance for the use of microporous filter membranes

With the rapid development of economy and technology, many enterprises have started to use microporous filter membranes. To protect and extend the service life of the filter membranes, enterprises should immerse the treated filter membranes in injection water at the same temperature as the drug solution for 5-10 minutes. After use, the microporous filter membranes are placed in injection water to prevent drying, which is an important means to ensure the quality of microporous filter membranes. The core part of the microporous filter membrane is the filter element, which needs special protection as it is a vulnerable component and cannot be reused multiple times. Below is a detailed introduction to the relevant content.

A Brief Introduction to Filter Membranes

When developing analytical methods related to dissolution experiments and content of formulation samples, due to the influence of auxiliary materials, it is necessary to filter and continue the filtrate as a reagent solution. A filter membrane is required during the filtration process. The material and type of filter membrane sometimes have a significant impact on the sample, and different filter membranes need to be screened.
