Ultipor® VF Grade DV50 Virus Removal Filter Cartridges by Pall Life Sciences Products - Biopharmaceutical Division

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 include purification of BioPharmaceuticals, tissue and plasma derivatives, protein additives, culture media, diagnostic reagents, buffers and diluents.
