Integrity testing of PTFE bubble point membrane
PTFE bubble point membrane, as a new type of filter material, is widely used in various industries. It can be said to be very popular. The membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, it can trap all dust particles including bacteria, so it has a wide range of applications.
Although the definition of sterilizing (stage) filters is based on the interception efficiency of microorganisms, the microbial challenge test is a destructive method and is not suitable for meeting GMP requirements. Both the production site and the filters that will be used for pharmaceutical production are polluting, and therefore cannot be used as a monitoring method in daily pharmaceutical production. Therefore, the importance of integrity testing as an “indicator” of interception efficiency is self-evident.
Polytetrafluoroethylene bubble point film is a new material made of polytetrafluoroethylene film that has been stretched vertically and horizontally in both directions. It is acid-resistant, alkali-resistant, and resistant to various organic solvents. It is almost insoluble. to all solvents. Its friction coefficient is extremely low, so it can not only provide lubrication, but also become an ideal coating for easy-to-clean woks and the inner layer of water pipes. Therefore, it is an indispensable product in aviation, navigation, aerospace, communications, electronics, military, weapons and other industries.
It is a polytetrafluoroethylene bubble film manufacturer integrating production, sales and customization. The company has advanced PTFE membrane production lines and composite production lines. The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
