These new prefilters feature a combination of high performance polyethersulfone (PES) membranes and nanofleece technology. This is the first time that PES nanofleece material is being used for liquid prefiltration applications in biopharmaceutical manufacturing. The newly developed nanofleece technology provides an ultrafine fleece structure based on a small nanofiber diameter of 120-150 nm compared with the fiber diameter of conventional fleece materials of >500 nm. The resulting fleece structure offers enhanced clarification capabilities, even for extremely fine contaminants, along with a high-dirt holding capacity, fast flow rates and high total throughput performance. Sartoguard NF filter elements are available in all common filter formats offered by the company, such as SartoScale devices for small-scale filterability trials, as well as MidiCaps, MaxiCaps and standard filter cartridges for medium- and commercial-scale manufacturing. Sartoguard NF MidiCaps and MaxiCaps are the first fully gamma irradiatable prefilter series and can be easily integrated into single-use process equipment.
