The GPSX Capsule Filter features a single-layer hydrophilic PES membrane, designed for general service filtration where cost-effectiveness and performance matter. With low binding characteristics, GPSX is ideal for aqueous solutions that contain ingredients prone to adsorbing onto filter media.

Optimized for fine particle removal and prefiltration, GPSX filters scale reliably from lab to production while maintaining consistent results.
