LOFMEM-E™ Polyethersulfone (PES) Membrane filter cartridges are designed for ultrapure water filtration. LOFMEM-E™ cartridges are inherently hydrophilic and contain no added surfactants or wetting agents.
LOFMEM-E™ Ultrapure water filter cartridges are used by the microelectronics industry for final filtration of ultrapure water. The polyethersulfone membrane provides high contaminant capacity, superior flow rates and consistent removal of particles and microorganisms.
LOFMEM-E™ filter cartridges are manufactured in ISO Class 7 cleanroom, 100% flushed with 18 MΩ-cm DI water and integrity tested. Resistivity rinse-up to 18 M Ω-cm and single digit ppb TOC levels in less than 30 minutes at 11.36 l/min (3 GPM) per 10-inch element. All LOFMEM-E™ filter cartridges have the pore size, lot and serial number stamped on each filter element for identification and traceability.
