Abstract:
1. A dispensing device, comprising: a first vessel, storing a first liquid and a second liquid, the second liquid being immiscible with the first liquid and having a lower specific gravity than the first liquid; a second vessel, storing the second liquid; a tube; a pump; and a controller, which controls a suction and pressurization performed by the pump, wherein the controller is programmed to: suck the second liquid contained in the first vessel into the tube through one end of the tube, suck the first liquid contained in the first vessel into the tube through the one end of the tube so that the tube has the first liquid and the second liquid, suck the second liquid contained in the first vessel into the tube through the one end of the tube so that in the tube, the first liquid is sandwiched by the second liquid, discharge the second liquid which has been sucked into the tube into the second vessel in which the second liquid already exists, discharge the first liquid which has been sucked into the tube into the second liquid contained in the second vessel, and discharge at least a part of the second liquid which has sucked into the tube into the second vessel.
