Patent ID: 8152707

Claim:
A bio cell cleaning centrifuge comprising: a motor that has a drive shaft; a rotor that is engaged with the drive shaft to be rotated by the motor; a plurality of holders that are equipped on the rotor in a circular array to be rotated together with the rotor and that hold a plurality of test tubes so as to be pivotable toward a rotational radial direction of the rotor, central axes of the holders being inclined toward a rotational tangent direction of the rotor; a cleaning liquid distributor that is mounted on the rotor to be rotated together with the rotor and that supplies a cleaning liquid to the plurality of test tubes; and a controller configured to control the motor to rotate in a first direction in an injection process in which a cleaning liquid is injected into the plurality of test tubes and to rotate in a second direction that is opposite to the first direction in a supernatant discharge process in which the cleaning liquid is discharged by rotating the rotor while locking the plurality of holders in the vertical state by a locking mechanism.
