An integrated weighing system assures the required quality of filtration, buffer feed, and cleanup. Good ergonomics was a major priority in designing user friendly interfaces for the bag, filter and tubes. If the filter becomes clogged, a pressure monitor detects the excess pressure in the tube and stops the process. The team laid the technical groundwork for connecting a chromatographic sampler to the filtration system via a pump line and integrated this connection into the control system. The pump line includes a flushing agent connection and dispenser, a sprayer and a bypass system to the sampler. The line was developed in parallel with the filtration system and installed in an existing climatic chamber.
