PendoTECH tangential-flow filtration (TFF) process control systems have been widely adopted in the filtration community. The system’s features enable its implementation in multiple unit operations and biopharmaceutical processing applications, including ultrafiltration–diafiltration (UF–DF) of proteins, viruses, and compounds such as oligonucleotides and antibody–drug conjugates (ADCs). The control system can be used to develop process parameters for UF–DF processes that have different membrane formats (e.g., flat-sheet cassette and hollow fiber). TFF laboratory setups often are manual or semiautomated processes that use pumps,…
