GSPES-Series Serial-Layer Polyethersulfone
The serial-layer design makes the GSPES an ideal choice for the clarification or particulate-heavy solutions in a wide variety of food & beverage, pharmaceutical, biological, and high-purity chemical applications.
GSPES-Series Overview
GSPES filter cartridges deliver extended service life and excellent retention. The serial-layer design makes the GSPES an ideal choice for the clarification or particulate-heavy solutions in a wide variety of food & beverage, pharmaceutical, biological, and high-purity chemical applications. The GSPES series is available in 0.2, 0.45, & 0.65-micron ratings. The serial-layer design offers superior throughput volumes while protecting downstream sterilizing grade cartridges.
Each cartridge is flushed with 18 megohms High Purity deionized water and is integrity tested to ensure the delivery of clean effluent with low extractables. Designed to tolerate repeated hot water sa- nitization and in-situ steam sterilization cycles for maximum service life.
