Sartoguard® NF membrane prefiltration filter elements with Nanofleece Technology feature a unique combination of well-proven polyethersulfone (PES) membranes coupled with highly innovative nanofiber (NF) technology. NF creates a compelling value proposition based on: ultrafine retention of particles and other contaminants; outstanding total throughput with three filtration layers and a high 0.65 m2/10″ membrane area; excellent protection offered to 0.2 ?m sterilizing grade and 0.1 ?m mycoplasma retentive filters; first gamma-irrradiatable triple-layer all-PES filter on the market that allows easy integration into single-use assemblies; and integrity testing prior to release and testability at the customer site for performance verification. Comprehensive analysis of widely used prefilters on the market have resulted in convincing data that shows that these elements outperform the best competitive prefilters for cell culture media and downstream column guard filtrations alike.
