PureFlo® PES mini filter cartridges are highly-retentive hydrophilic PES membrane filters that have been specially designed for critical applications. The PES membrane in an all-polypropylene construction provides excellent chemical compatibility and superior flow per surface area as compared to other membrane cartridges. No adhesives, binders, or surfactants are used in the manufacturing process. All cartridges 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. In addition, unlike hydrophobic filters such as PTFE, the hydrophilic membrane reduces the potential for bubble formation by not de-wetting in outgassing fluids . All filter cartridges are 100% integrity tested to ensure filter performance each and every time out of the package. PureFlo® PES minifilter 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.
