Kleenpak™ capsules with Posidyne™ membrane, a Pall Life Sciences product, incorporate a covalent charge-modified Nylon 6,6 membrane that provides enhanced retention of fine particles smaller than the membrane’s rating. Posidyne membrane in Kleenpak capsule meet cleanliness requirement per USP Particulates in Injectable. It features positive Zeta potential for enhanced efficiency in aqueous solutions. Capsules contain a double-layer sterilizing membrane for high reliability and high-quality product. Filters are self-contained and designed for small sterile filtration systems throughout a range of acidic to basic solutions. Kleenpak liquid capsule filters with intrinsically hydrophilic positive zeta potential Posidyne membrane are rugged, self-contained sanitary filters designed for small-batch sterile filtration of aqueous pharmaceutical solutions. With a net positive charge in most aqueous solutions from pH 3 to 10, Kleenpak Capsules with Posidyne Membrane Assemblies can effectively remove contaminants such as cell debris and endotoxin smaller than the filter rating.
