PSE Cartridge W - Specifications

NEW

In order to meet strict contamination control requirements for ultra-pure water, polysulfone membranes have been employed because they are excellent high-polymer separation membranes.
The lineup includes membrane pore sizes of 0.1 µm, 0.2 µm, 0.45 µm, 0.8 µm, and 1.2 µm.

Sterilization treatment

The cartridge can be repeatedly sterilized. Sterilization should be carried out at regular intervals to ensure reliable removal of microorganisms and to maintain filtration performance.

Hot water sterilization

90℃

Chemical sterilization

  • Hydrogen peroxide solution: 5%

  • Formalin: 1%

  • Sodium hypochlorite: 10 ppm (chlorine water)
