Abstract
There is provided a centrifuge that includes a motor, a rotor chamber accommodating a rotor that is rotated by the motor, a vacuum pump that sucks air from the rotor chamber to reduce a pressure therein, a controller that controls the centrifuge to operate selectively in one of a normal centrifuge operation mode and a pulsed operation mode in which the rotor is rotated for a short time at a speed equal to or lower than a predetermined set value, and an interface device connected to the controller to input information regarding the operation mode of the centrifuge, wherein the controller controls the vacuum pump to turn on when the centrifuge operation mode is selected by the interface device and to turn off when the pulsed operation mode is selected.
