Pharmaceutical Manufacturing Case Study: single-use BPR improves Trans Membrane Pressure in novel Single Pass TFF control strategy

This summer, the Journal of Membrane Science published a paper focusing on automated control of Trans Membrane Pressure (TMP) in a Single-Pass Tangential Flow Filtration (SP-TFF) system. Control was substantially improved by using an Equilibar® single-use dome-loaded multi-orifice back pressure regulator (BPR) rather than traditional technologies.
