Pleated Polyethersulfone (PES) Membrane for Final Filtration of Ultrapure Water
ZTEC-E microelectronics grade cartridges represent Graver’s latest development in ultrapure water filtration technology. The filters are inherently hydrophilic and contain no added surfactants or wetting agents that could contaminate pure and ultrapure water streams. The PES membrane offers superior flow characteristics, high contaminant capacity and consistent removal of sub-micron particles. The cartridges exhibit rapid rinse-up to 18 M W-cm resistivity and single digit ppb levels of TOC.
