Ultipor® GF Plus Filters – AB Cartridge Style

Pall Ultipor GF Plus® filter cartridges are made with positive Zeta modified glass fiber media for enhanced efficiency. The single open ended (SOE) AB style cartridges feature a high area pleated element construction designed to fit in sanitary style filter housings. A bio-safe low extractables binder resin covalently immobilizes the glass fibers and imparts a strong positive charge in aqueous service. In addition to the high particulate removal efficiency and low pressure drops consistent with glass fiber media, the added positive Zeta charge enables Ultipor GF Plus filters to effectively remove submicron haze particles or endotoxins from a wide variety of aqueous biological, pharmaceutical, cosmetic and toiletry solutions.
