Did you know that Teflon liquid filtration membrane is used in the pharmaceutical process for impurity removal, concentration and sterilization? It plays an important role in key steps. Let’s take a closer look at this material.
Usually through two or more filtering methods of the same or decreasing pore size, collectively called sequence filtering. In the sequential filtration system, if a sterilizing grade filter is added before the final sterilizing filter, and the sterility between the two filters is ensured, and the microbial contamination level of the pre-filtration medium is controlled to be generally less than or equal to 10cfu/100ml, this kind of This situation is called a redundant filtering system.
Teflon liquid filtration membrane is generally made of polytetrafluoroethylene (ptfe) suspended powder, which is expanded and stretched to form a microporous film. PTFE liquid filtration membrane has a fibrillar microporous structure with a porosity of more than 88%. There are 1.4 billion micropores per square centimeter, with a pore size range of 0.1μm-0.5μm. This membrane is laminated on various fabrics and substrates using a special process. It can become a new type of filter material. The membrane has small pore size, uniform distribution and large porosity. It can filter all dust particles including bacteria while maintaining air circulation.
It is a Teflon liquid filtration membrane manufacturer integrating production, sales and customization. The company has advanced PTFE film production lines and composite production lines. The company’s products are widely used in various fields.
