During concentration and buffer exchange (UF/DF), high-fold concentration and thorough buffer exchange must be achieved while controlling transmembrane pressure (TMP) and flow rate. Pump flow stability, low shear, and system controllability directly affect yield, membrane lifetime, and process scalability.
