Abstract: A centrifugal rotor includes a support disk and a centrifugal carrier. The centrifugal carrier is assembled within the support disk. The centrifugal carrier includes an arc-shaped body, a sample application chamber, a sample metering chamber, a diluent chamber, a diluent metering chamber, a metering control member and a mixing chamber. The sample metering chamber is communicated with the sample application chamber. The sample metering chamber is positioned radially outward from the sample application chamber. The diluent metering chamber is communicated with the diluent chamber. The diluent metering chamber is positioned radially outward from diluent chamber. The metering control member is slidingly connected within or detachably fixed to the sample metering, chamber or the diluent metering chamber. The mixing chamber is communicated with the diluent metering chamber and the sample metering chamber respectively.

Abstract: A centrifugal rotor includes a rotor body, a diluent container, a piercing structure and a capping film. The rotor body has a receiving cavity. The diluent container is located within the receiving cavity and has a seal film. The piercing structure is located within the receiving cavity and in contact with the seal film. The capping film is located over the diluent container and the piercing structure for securing the diluent container and the piercing structure within the receiving cavity.

Abstract: Disclosed herein is a centrifugal rotor for delivering and analyzing biological sample. Chambers within the centrifugal rotor is used to split a biological sample, which comprises biological cellular components and biological fluids, into separate parts under centrifugal force after the biological sample being diluted, metered and distributed by the centrifugal rotor.

Abstract: A fluid transferring apparatus includes a frame, a sample inlet chamber, a filling channel, a plurality of filling passageways, a plurality of test wells, and a plurality of venting passageways. The sample inlet chamber is disposed within the frame. The filling channel is disposed on the frame and connected to the sample inlet chamber, wherein the filling channel has a top part above the outlet of the sample inlet chamber. The filling passageways are disposed on the frame and connected to the filling channel. The test wells are disposed within the frame and connected to the filling passageways respectively, wherein the test wells are below the top part of the filling channel. The venting passageways are connected to the test wells respectively.
