Sartorius Stedim Biotech (SSB) launched the Sartoguard NF prefilter series, completing its range of Sartoguard prefilters. 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.
Protec RF0.5 borosilicate glass fiber prefilter removes colloids, aggregated and non-product proteins, lipids and particles to protect membrane filters downstream. The 0.5 μm-rated prefilter provides high flow rates and high contaminant holding capacity. The filter is cleanroom manufactured.
