GGPES

Summary

Product identification

GGPES-Series High Purity General Grade Polyethersulfone Filter Cartridges are designed for cost-effective, general-purpose membrane filtration. They feature a highly retentive polyethersulfone membrane with excellent flux density and low protein-binding, which is naturally hydrophilic for easy wetting and maximum surface utilization. These cartridges offer lower pressure loss and longer service life due to extended filtration area. They are designed to tolerate repeated hot water sanitization and in-situ steam sterilization cycles. Manufactured in a clean-room environment.
