Posidyne® Filter Cartridges by Pall Life Sciences Products - Biopharmaceutical Division

Pall Posidyne filter cartridges incorporate a patented covalent charge-modified Nylon 6,6 membrane which exhibits a net positively-charged Zeta potential in aqueous solutions. This positive Zeta potential provides enhanced retention of fine particles smaller than the membrane’s rating, such as endotoxins in water, in a direct flow mode without the higher pressure drop of finer filters. High-area pleated into single open-ended (SOE) AB sanitary-style cartridges, N66 Posidyne filters are available in particulate and bioreduction grades and in sterilizing-grades.
