SPSHR Low Diffusion Flow PES Sterilizing Filter Cartridge (CAT#: STEM-BC-0046-ZJF)

SPSHR is a low diffusion flow sterilizing-grade PES filter cartridge designed for reliable sterile filtration of pharmaceutical liquids. It is suitable for large-volume parenterals, small-volume injections, bulk pharmaceutical solutions, buffers, and aqueous antibiotic materials. The filter provides a low diffusion flow level and establishes correlation between integrity test values and bacterial challenge performance. Each cartridge undergoes bubble point and diffusion flow testing during manufacturing. The hydrophilic Polyethersulfone Filter Membrane supports wetting and integrity testing. The product is available in scalable formats for development through production. Each filter has an independent serial number for full traceability. The cartridge supports repeated online steam sterilization and autoclave sterilization.
