PES filter cartridges are highly retentive hydrophilic. PES membrane filters that have been specially designed for critical applications. The PES membrane in an allpolypropylene construction provides excellent chemical compatibility and superior flow per unit area as compared to other membrane cartridges. No adhesives, binders, or surfactants are used in the manufacturing process and all car tridges are rinsed with high-purity water to reduce extractables and downtime. The hydrophilic PES membrane does not require pre-wetting with IPA and flushing with DI water, thereby eliminating a potential source of contamination and hazardous waste. PES filter cartridges are well-suited for critical applications where superior flow and particle removal efficiency at 0.04, 0.1, 0.2, 0.45, 0.65, 0.80 and 1.2 micron is required.
