SPSH Low-Diffusion Sterile Filter Cartridge, PES, 0.22 μm (CAT#: STEM-BC-0131-ZJF)

The SPSH filter cartridge is a low-diffusion, hydrophilic Polyethersulfone Filter Membrane filter for liquid sterilization. It features smaller membrane pores in the center and larger on the sides to reduce damage and extend lifetime. Each cartridge has a unique serial number for traceability. It withstands high temperatures and passes 100% integrity testing before shipment. The cartridge is suitable for production water, wine, fruit wine, and other liquid sterilization applications. It can withstand steam sterilization and provides verified sterility.
