A centrifuge including a temperature sensor measuring ambient temperature is provided. Centrifugation operation is available or not is determined in accordance with a type of a rotor, the ambient temperature, or operation conditions set by a user. When it is inoperable, a display device displays that it is inoperable so as to invite the user to select necessity of modification of the operation conditions. Upon the display, modified operation conditions which are candidates of operable operation conditions are displayed to let the user select a candidate. To operate under the selected setting operation conditions, the display device displays that the operation is working under modified conditions.

Centrifuge having rotor and cooling device for cooling rotor

According to an aspect of the present invention, there is provided a centrifuge in which a steam sterilization of a sample flow passage is performed, the centrifuge including: a rotor configured to centrifuging a liquid sample; a drive portion that drives and rotates the rotor; a chamber that accommodates the rotor therein, the chamber having a first and a second penetration holes provided on an upper and a bottom portions thereof, respectively; and a first and a second valves disposed on the first and the second penetration holes, respectively; wherein a cooling gas is introduced through one of the first and the second penetration holes and discharged through the other to cool a periphery of the rotor before or after execution of a centrifuging operation of the liquid sample.

Centrifuge with steam sterilization

In a centrifugal chamberan elastic rotation shaftand a high-rigidity rotation shaftextend coaxially. When a rotor selected from an angle rotorand a swing rotorwhich have different sizes and shapes is set in the centrifugal chamberan optimal shaft is connected automatically to the selected rotor. The angle rotorhaving a low tendency toward mass eccentricity is supported and rotated by the elastic rotation shaftfor high-speed rotation. The swing rotorhaving a high tendency toward mass eccentricity is supported by the high-rigidity shaftfor low-speed rotation. Rotation torque is transmitted to the swing rotorfrom the elastic rotation shaft.
