A device holder (20) for holding a transfer device (800) is provided on a stage (10). The device (800) has a first connector (810) to which a first container (910) can be connected, a second connector (820) to which a second container (950) can be connected, and a connection port (850) to which a syringe (980) can be connected. The stage (10) can be turned to a first turning position where the first connector (810) is located higher than the second connector (820), and a second turning position where the second connector (820) is located higher than the first connector (810). A second container holder (50) holding the second container (950) coaxially with the second connector (820) can turn integrally with the stage (10) and move linearly along the direction of the axis of the second connector (820).
