Puritech PuriPB series PVDF Filter Cartridges

Puritech PuriPB series PVDF Filter Cartridges is made of a high porosity hydrophilic polyvinylidene fluoride membrane. It’s optimized for high retention efficiency, flow rate and long life time. The cartridges in order to reduce bio-burden and turbidity are highly compatible with the most rigorous sanitizing methods in the pharmaceutical industry. Also it’s available for other purpose of food & beverage, electronics, high purity chemical and various industrial applications. These 100% integrity tested cartridge filters are in compliance with FDA 21 CFR 177.1655.
