WCPES-Series WaterClear™ Grade Polyethersulfone

WCPES-Series High Purity WaterClear™ Grade Polyethersulfone Filter Cartridges are a value-oriented, reduced surface area choice for cost-effective, general-purpose membrane filtration. Designed in continuous lengths up to 30” segments* for excellent performance value. The highly retentive polyethersulfone membrane offers excellent flux density and low protein binding. The naturally hydrophilic membrane wets easily to allow maximum utilization of the entire surface. These features allow the WCPES-Series to provide the fine performance of PES membrane at a competitive price.
Designed to tolerate repeated hot water sanitization and in-situ steam sterilization cycles. Manufactured in a clean-room environment to maintain high standards of purity and cleanliness.
