As the requirements for sterilizing filtration technology continue to increase, the ASTM F838 industry standard measurement method for defining 0.22μm sterilizing filtration membranes emerged at the historic moment, and this standard measurement method It is still used today. Not all processes require true “sterilization grade”. For biopharmaceutical processes, only the bioreactor feeding process and filling process require the use of absolutely precise sterilizing grade filtration products, and the requirements for sterilizing capabilities are quite strict.
PTFE sterilizing filter membrane adopts a special two-way pull It is prepared by extension technology, which can ensure the interception of all impurities such as small bacteria and has a large flux. The material has high and low temperature resistance (-200℃-260℃). It will not age, split, or discolor after long-term use. It has strong weather resistance, strong acid and alkali resistance, and wide chemical applicability. When used for gas filtration, PTFE sterilizing filter membrane can intercept all kinds of phages, bacteria and particles above 0.02um.
Polymer separation membrane is a membrane made of polymer or polymer composite materials with the function of separating fluid mixtures, also called functional membrane. Membrane separation is based on the selective permeability of the membrane. The separation membrane is used as a spacer layer. Under the driving force of pressure difference, concentration difference or potential difference, each component in the fluid mixture has different rates of permeation through the membrane, so that it can pass through the membrane at different rates. Both sides are enriched separately to achieve the purpose of separation, refining, concentration and recycling.
