Ultipor™ VF Grade DV50 virus removal filters, part of our Pall filtration portfolio, offer a robust means to remove viruses from liquids by microfiltration, while permitting enhanced transmission of proteins.

The filters feature 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. Ultipor™ VF filters 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, a Pall Life Sciences product 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.
