摘要: A system for ultrafiltration employs a crossflow filtration module for extracting a fraction from a sample fluid (e.g., blood) and a recirculating permeate loop to produce a concurrent permeate flow through the filtration module to maintain a positive transmembrane pressure at all points of the crossflow filter. Permeate in the recirculating loop is enriched by a processing module and stabilized by removing an enriched fraction thereof. In an embodiment, the enriched fraction is concentrated plasma that is returned to a patient.
