The purpose of the present invention is to provide a device which automatically performs a step in which expanded and cultured cells are diluted to a desired cell concentration and re-inoculated. The present invention is related to a cell-number adjustment device characterized by being provided with: an inlet for taking in a cell suspension; an outlet for discharging a diluted cell suspension; and a flow path which is provided between the inlet and the outlet, and which is capable of holding the cell suspension. The cell-number adjustment device is further characterized in that: the flow path has, provided thereto, a liquid delivery pump for causing the cell suspension inside to flow, a cell-number measurement instrument for extracting data related to the cell-number concentration per unit amount of the cell suspension, and a dilution-liquid container for holding a dilution liquid which is supplied to the flow path to dilute the cell suspension; a control unit for controlling at least the liquid delivery pump on the basis of the data obtained by the cell-number measurement instrument is further provided; and the control unit determines, on the basis of the data obtained by the cell-number measurement instrument, the dilution liquid amount required to set the cell-number concentration to the desired concentration, and drives the liquid delivery pump such that the required amount of the dilution liquid is taken into the flow path and mixed with the cell suspension. |
