Electronics Grade Cartridges

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 submicron particles. The Cartridges exhibit rapid rinse up to 18 Meg Ohm-cm resistivity and single digit ppb levels of TOC.
