PROBLEM TO BE SOLVED: To achieve increasing liquid volume to be sent by a pump or sending an equal volume of liquid to a plurality of culture vessels, and to achieve miniaturizing the whole apparatus, improving the efficiency of flow path installation work, or the like, in mass culturing.SOLUTION: By providing an intermediate tank 12, a flow path consisting of a tube 14 through which cells and medium pass is separated from a pump 13, and a multipoint valve mechanism 20 valve-switchable to send liquid to an optional port is connected between the intermediate tank 12 and a culture vessel 11 having a plurality of ports. The multipoint valve mechanism 20 consists of a detachable first valve mechanism and a second valve mechanism, and the improvement in ease of installation of a flow path and the prevention of installation mistake can be achieved by detachment. Thereby the minimization of the whole device, the improvement of the efficacy of a flow path installation work, and a device configuration for minimizing cell damage are enabled.SELECTED DRAWING: Figure 1 |
