Centrifugal rotor with arc-shaped centrifugal carrier or weight body

A centrifugal rotor comprising:

• a support disk having a plurality of concave areas;
• and
• a carrier disk assembled within the support disk and haying at least two arc-shaped centrifugal carriers, each arc-shaped centrifugal carrier is assembled within a corresponding one of the plurality of concave areas, wherein each centriftrual carrier comprises:
• an arc-shaped body;
• a sample application chamber disposed on the arc-shaped body;
• a sample metering chamber disposed on the arc-shaped body, and communicated with the sample application chamber, the sample metering chamber being radially outward from the sample application chamber;
• a diluent chamber disposed on the arc-shaped body;
• a diluent metering chamber disposed on the arc-shaped body and communicated with the diluent chamber, the diluent metering chamber being radially outward from diluent chamber;
• a metering control member detachably fixed to and installed inside the sample metering chamber or the diluent metering chamber, wherein the metering control member is in contact with an inner bottom wall of the sample metering chamber or the diluent metering chamber that is closest to the support disk, and not in contact with an inner surrounding sidewall of the sample metering chamber or the diluent metering chamber, and not in contact with an inner wall of a delivery channel that is communicated with the simple metering chamber or the diluent metering chamber when the metering control member is fixed to the sample metering chamber or the diluent metering chamber;
• and
• a mixing chamber disposed on the arc-shaped body and communicated with the diluent metering chamber and the sample metering chamber respectively, the mixing chamber being radially outward from both the diluent metering chamber and the sample metering chamber.
