0.8 micron PES membrane pleated filter cartridge for high purity water
Imported high precision PES filter membrane is adopted in the product as filter media. The product is produced by overall structure sweat welding. It has excellent filtration performance and ability of completely intercepting bacteria.
1.The filter membrane is hydrophilic with absolute filtration accuracy
2. Low protein adsorption performance
3.Wide chemical compatibility
4. Extremely low precipitates
1.Sterile filtration of vaccine
2.Sterile filtration of blood products
3.Sterile filtration of raw material medicine, injections, infusion and other drugs
4.Filtration of cell culture medium
5.Filtration of de-ionized water
6.Terminal filtration of semiconductor wet equipment;
