Positively Charged PES Membrane Capsule Filter (General Purpose) – GPC

Click here for more information

The GPCX Capsule Filter is built with a positively charged, single-layer Polyethersulfone (PES) membrane designed for high-efficiency removal of endotoxins, viruses, and negatively charged fine particles. Its economical design provides dependable prefiltration performance in less critical applications while lowering the total cost of filtration.

With high flow rates, broad chemical compatibility, and scalable construction, GPCX offers a reliable solution for upstream protection of critical process filters or as a stand-alone clarifier in aqueous systems.
