Title:
CENTRIFUGE
Document Type and Number:
WIPO Patent Application WO/2020/261744
Kind Code:
A1
Abstract:
In a centrifuge for washing living cells such as blood cells, control of the remaining amount of a supernatant according to the related art largely depends on controlling the rotational speed of a motor, and thus a highly accurate motor control means is required to prevent overshooting. In place of the related art, an easy control method is required. In the discharging of a supernatant discharge by a centrifuge having a plurality of test tube holders that can radially swing through centrifugal force, a holding means using an electromagnet that can control the swinging of the test tube holders, and a cleaning liquid distribution element that supplies a cleaning liquid into a test tube, a first decant operation (round 3-1) is executed by rotating a rotor in the order of acceleration, setting, and deceleration in a state in which the swinging angle of the test tube is limited and discharging the supernatant of the cleaning liquid from the test tube, and a second decant operation (round 3-2) is executed, at a time of a final decant operation, by accelerating the rotor, releasing limitations on the swinging angle during the acceleration, and then decelerating the rotor.
