Centrifuge with acceleration and deceleration time display

A centrifuge comprising:

• a driving unit which rotates a rotor on which a sample is held;
• an input/output unit which receives input information indicative of a set rotation speed of the rotor and a set operation time period for performing a centrifugal operation from a user therethrough;
• a control unit which controls a rotation speed of the rotor based on the received input information and that includes a controller configured to calculate a first time information indicative of an amount of the set operation time period remaining until the rotor speed of the rotor arrives at the set rotation speed based at least upon (i) rotor information which is associated with the centrifuge, (ii) input set rotation speed and (iii) rotation acceleration inclination pattern;
• and
• a display unit configured to display the information of the set rotation speed of the rotor and the set operation time period for performing the centrifugal operation, and further, when the rotor is rotated, to display the first time information indicative of the amount of the set operation time period remaining until the rotor speed of the rotor arrives at the set rotation speed,
• wherein the control unit stores a plurality of rotation acceleration inclination patterns of the rotor, and
• wherein the control unit calculates the first time information from a corresponding one of the rotation acceleration inclination patterns that is selected from the stored rotation acceleration inclination patterns based on an actual rotation acceleration inclination of the rotor rotated by the driving unit.
