Abstract: 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.
