Title: FILTRATION SYSTEM INCORPORATING VISCOMETER
Abstract:
A filtration system (10), in particular for a low volume tangential flow filtration process, comprises a filter device (24) including at least one membrane (18), and at least one input (12) for supplying a feed stream to a retentate loop (14). The retentate loop (14) includes a pump (16) for circulating the feed stream along one side of the membrane (18). The filtration system (10) further comprises a retentate output (22) allowing retentate to exit the retentate loop (14), and a permeate output (20) allowing permeate to exit the feed stream at the other side of the membrane (18). The filtration system (10) is characterised by a viscometer (42) integrated in the retentate loop (14).
