Abstract: Disclosed is a fraction collector for dispensing liquids into plural receptacles (P1,P2) arranged in a two dimensional array. The fraction collector comprises a table (22) for supporting said receptacles, and an arm supported above the table, in tum supporting a liquid dispenser (35), the fraction collector arm is rotatable about an arm axis (C) and the liquid dispenser is movable along the arm on a carriage 34 (FIG. 2). Thereby, the dispenser is low cost and is repositionable simply above the receptacles as a result of said rotation and as a result of said movement along the arm, without occupying too much laboratory bench space.

Abstract: The present disclosure relates to a mixing device (9) comprising an inlet channel (25), an outlet channel (27), a mixing cavity (29) and a laminar mixing element (31) arranged within the mixing cavity. The inlet channel extends along an axis (21) of the mixing device from a first end (23) of the mixing device to the mixing cavity. The outlet channel extends along the axis from the mixing cavity to a second end (24) of the mixing device arranged opposite to the first end. The mixing cavity is arranged between the inlet channel and the outlet channel and extends in an axial direction (A) along the axis and in a radial direction (R) outwardly from the axis to an outer wall (30) of the mixing cavity. The laminar mixing element extends radially across the mixing cavity, subdividing the mixing cavity into an inlet portion (26) and an outlet portion (28). The mixing element comprises a plurality of holes (41) extending through the mixing element. The said holes are distributed over the mixing element.

Abstract: A method includes measuring, by a flow sensor (70), a flow rate of a permeate fluid (48) flowing through a filter (20) of a membrane filtration system (12). Further, the method includes receiving, by a control unit (86), the measured flow rate of the permeate fluid (48) and determining, by the control unit (86), a first flux rate of the filter (20) based on the measured flow rate of the permeate fluid (48). Furthermore, the method includes comparing, by the control unit (86), the determined first flux rate with a first predetermined flux rate. Additionally, the method includes operating the membrane filtration system (12), by the control unit (86), in a normal mode or a flux tolerant mode based on the comparison of the determined first flux rate with the first predetermined flux rate. The flux tolerant mode of the membrane filtration system (12) is further based on a determined normalized water permeability value of the filter (20).
