Abstract
The invention relates to a device for processing an initial liquid medium (4) comprising cells in an initial concentration in order to obtain a product liquid medium (4′) comprising cells in a product concentration, the device (2) comprising a separator (6) adapted to separate the initial liquid medium (4) into various constituents, a first supply system (8) for supplying the initial liquid medium (4) to the separator (6), a first outlet system (12) for extracting the product liquid medium (4′) from the separator (6), a sensor (22, 22′) adapted to measure a physical parameter related to the concentration of the cells in the initial or product liquid medium (4, 4′), and a control unit (24) coupled to the sensor (22, 22′) and adapted to control at least one process of the device (2) as a function of the physical parameter measured by the sensor (22, 22′). The device is characterized by a second supply system (10) for supplying a solution (18) to the separator (6) with a given flow rate. The flow rate of the solution (18) in the second supply system (10) during its supply to the separator (6) is determined based on the at least one process parameter.
