Cytiva, AB2NFZ7PH4, Pall™ Posidyne™ membrane filter cartridge, 0.2 µm removal rating, endotoxin control, 20-inch length, double o-ring (silicone) with bayonet lock and fin end

Posidyne™ filter cartridges, part of our Pall filtration portfolio, incorporate a covalent charge-modified Nylon 6,6 membrane that provides enhanced retention of fine particles smaller than the membrane’s rating.
Posidyne filter cartridges incorporate a 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.
