Accommodating needs of researchers and engineers, self-contained CF042 suits research and development, small batch processing, and larger commercial system simulation processes. This modular, multi-line, fully integrated, tangential flow flat-sheet testing system has built-in touchscreen that displays and records information from integrated sensors in real-time. Each membrane test cell has effective active area of 42 cm², which affords 250 cm² max active area when configured as 6-cell system.
