Pall Ultipor VF virus removal filter cartridges feature innovative hydrophilic PVDF microporous membranes to remove significant levels of viruses from biological solutions, while enabling > 95% transmission of proteins up to 300 kD or larger. Using patented Ultipleat crescent-shaped pleated elements, the filters to incorporate 1.6 m2 (17.5 ft2) of filter area per 10 in. (254 mm) element in standard single open-ended (SOE) AB sanitary style cartridges. Ultipor VF cartridges achieve practical flows and pressure drops while effectively removing nanometer-size viral contaminants with high protein yields. An optional sub-0.1 µm rated prefilter (Grade DVD) and Fluorodyne II filters enhance throughputs and employ the same PVDF membrane material for ease of validation. Typical applications inc...Read more
