step S11: the controller recognizes that a first reaction cup is disposed in the plurality of centrifugal stations.
The first reaction cup is a reaction cup with a sample.
Sensors may be provided in each of the centrifugal stations, respectively, and a controller may be connected to each sensor to determine whether the first reaction cup is provided in each of the centrifugal stations based on each sensor. The controller may also determine whether the first reaction cup is disposed in each centrifugal station based on other means, such as, but not limited to, manual identification.
Step S12: the controller judges whether a second reaction cup is arranged in a centrifugal station symmetrical to the centrifugal station where the first reaction cup is arranged.
The second reaction cup is a reaction cup with a sample.
After recognizing that a first reaction cup is arranged in a certain centrifugal station in the plurality of centrifugal stations, the controller can further judge whether a second reaction cup is arranged in the centrifugal station at the symmetrical position of the centrifugal station, and then determine the action to be executed in the next step based on the judgment result.
If the result of step S12 is no, step S13 is executed.
Step S13: the controller sets up the third reaction cup in the centrifugal station of the symmetry with the centrifugal station that first reaction cup was located.

If the judgment in step S12 shows that there is no second reaction cup in the centrifugal station symmetrical to the centrifugal station where the first reaction cup is located, that is, there is no reaction cup with a sample placed therein, the controller may control the related mechanism or component (e.g., the cup moving component) to move the third reaction cup into the centrifugal station symmetrical to the centrifugal station where the first reaction cup is located, so that the third reaction cup and the first reaction cup form gravity balance, thereby avoiding the shift of the center of gravity of the centrifugal component, further avoiding vibration and noise caused by the shift of the center of gravity of the centrifugal component, and improving the stability of the centrifugal operation.
Step S14: the controller controls the centrifugal component to mix evenly and centrifuge.
