DPSHSL High Efficiency Dual-Layer PES Sterilizing Filter Cartridge (CAT#: STEM-BC-0044-ZJF)

DPSHSL is a sterilizing-grade filter cartridge using a dual-layer hydrophilic Polyethersulfone Filter Membrane for reliable bacterial retention. The dual-layer design improves filtration safety and supports longer service life in pharmaceutical filtration processes. It is suitable for sterile filtration of traditional medicine injections, sterile APIs, ophthalmic solutions, liquid products, and buffer solutions. The cartridge provides broad chemical compatibility across pH 1-14. The structure includes Polyethersulfone Filter Membrane, polypropylene support, polypropylene housing components, PBT interface liner, and multiple seal material options. The filter can tolerate repeated steam sterilization cycles. It is integrity tested and traceable by unique serial number. The design supports reliable filtration performance while reducing system operating burden.
