Abstract
A centrifuge capable of suppressing a long-time depressurization as compared with the case of starting depressurizing after cooling has been completed as well as shortening a cooling time of a rotor and a sample in the rotor is achieved as compared with the case of starting cooling is at the same time with depressurization. Operation of a Peltier element is started at the same time with operation start of the centrifuge. A bowl is cooled by heat absorption of the Peltier element, and the rotor is cooled by the bowl with using ambient air as a thermal medium. At this time, a vacuum pump depressurizing a rotor chamber is in an OFF state (ambient conditions). After a predetermined time is elapsed, the vacuum pump is turned on to start depressurization of the inside of the rotor chamber.
