Abstract

A method for automated cleaning of a filter basket in a bioreactor includes determining permeability of the filter basket. A control unit controls a suction unit for suctioning a residual liquid from the liquid tank, a liquid metering unit for dispensing a liquid having a predetermined liquid volume into the filter basket controls the suction unit to empty the liquid tank by suctioning a filtered liquid volume, measures the volume of the suctioned liquid volume, and sending a first measurement signal to the control unit. The control unit determines a permeability quotient from the volume of the extracted filtered liquid volume to the volume of the dispensed predetermined liquid volume and compares the permeability quotient with a permeability threshold. The control unit then controls a cleaning unit to perform a cleaning process of the filter basket if the permeability quotient is below the permeability threshold.
