Description:
PES (Polyethersulfone) membrane filter is a hydrophilic, low protein-binding filter known for its high flow rates, excellent thermal and chemical stability, and broad compatibility with aqueous solutions. It is widely used in biological, pharmaceutical, and industrial laboratories for sterile filtration, clarification, and sample preparation, especially where fast throughput and sample integrity are essential.
