RF-UF-PES RF-UF-PES Polyethersulphone Membrane Filter

Overview

The RF-UF-PES features a naturally hydrophilic polyethersulphone (PES) membrane with a mirrored asymmetric pore structure. Validated for bacterial removal (LRV >7) per HIMA/ASTM F838-05. Excellent low protein binding — typically 10× lower than nylon, 2× lower than polysulphone. Extremely resistant to hydrolysis with exposure capability exceeding 2 years, making it ideal for ultra-pure water systems (18 MΩ·cm). All components FDA approved to 21CFR.
