MicroDoer™ PES-S series polyethersulfone (PES) pleated filter cartridges provide highly efficient micronic and submicronic retention and extraordinary cleanliness. Designed specifically for the demanding needs of the micro-electronics industry. The highly asymmetric PES membrane gives excellent permeability and particle removal at high flow rates and low pressure drop. Being hydrophilic, cartridges allow for fast and easy wetting in aqueous fluids. Cartridges receive an extra-duration ultrapure water rinse to attain the lowest level of extractable substances. Cartridges are 100% integrity tested to assure optimized retention performance.
