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.
