ABSTRACT:
The present invention is to present a dispenser which is capable of heating a liquid to an approximately constant temperature in the same time regardless of an aspiration amount of the liquid. The dispenser comprises a liquid holder for holding a liquid; aspiration amount information obtaining means for obtaining aspiration amount information indicating an aspiration amount of the liquid; an aspiration-discharge part for aspirating the aspiration amount of the liquid indicated by the obtained aspiration amount information into the liquid holder and discharging the liquid from the liquid holder; a heater for heating the liquid held by the liquid holder; a temperature sensor for detecting a temperature of the liquid held by the liquid holder; target temperature determining means for determining a target temperature of the liquid based on the aspiration amount of the liquid indicated by the obtained aspiration amount information; and controlling means for controlling the heater so as to conform the temperature detected by the temperature sensor to the target temperature.
