Abstract
A centrifuge comprises a rotor for holding a sample, a rotation chamber for housing the rotor, a motor for rotating the rotor, an oil diffusion pump for reducing a pressure within the rotation chamber, and a control unit for controlling the heater temperature of the oil diffusion pump for a target set temperature. The control unit changes the target set temperature from a first given temperature to a second given temperature that is lower than the first given temperature after a given period of time elapses since the start of control of the heater temperature.
