Meissner expands Protec range

Meissner says that the filter combines an outer layer of borosilicate glass microfibre media with an inner layer of Meissner’s proprietary hydrophillic PVDF membrane.

According to Meissner, Protec® RM filters effectively protect downstream membrane filters and equipment. They are claimed to provide consistent submicron contaminant removal, high dirt-holding capacity and high flow rates, while removing colloids, aggregated and non-product proteins, lipids and other particles. Typical applications include the clarification, prefiltration and bioburden reduction in biological liquids (including serum, plasma fractions and other blood products), vaccines, tissue and cell culture media, protein solutions, fermentation media and feeds, cell removal form fermentation broths, pre-column chromatography, and biopharmaceuticals.
