PES Terminal Pleated Filter Cartridge, 0.04-0.65 µm (CAT#: STEM-BC-2959-ZJF)

This PES cartridge is intended for final-stage filtration of high-purity and biological liquids. It uses an asymmetric polyethersulfone membrane with a highly uniform pore distribution. Natural hydrophilicity enables rapid wetting and high liquid throughput. Low adsorption helps preserve proteins and other valuable biological components. Polypropylene flow-distribution and support components stabilize the membrane during operation. The cartridge is thermally welded without adhesives and is designed to prevent fiber release. It can be used for injectable liquids, serum, culture media, antibiotics, beverages, ultrapure water, and electronic chemicals. Every cartridge receives purified-water rinsing and integrity verification before release.
