A device holder (20) that holds a transfer device (800) is provided on a stage (10). The device (800) includes a first connector (810) to which a first container (910) is connectable, a second connector (820) to which a second container (950) is connectable, and a connection port (850) to which a syringe (980) is connectable. 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) that holds the second container (950) coaxially with the second connector (820) turns together with the stage (10) and can be linearly moved along a direction of an axis of the second connector (820).
