ABSTRACT:
An assembly for separating, metering and delivering fluids such as whole blood, includes a central rotating member rotatable about a fixed spin axis. A processing chamber holding member is connected to the central rotating member by a centrifugally actuated frame. At rotational speeds below a first predetermined speed, the centrifugally actuated frame is in a first position. At rotational speeds greater than the first speed, centrifugal force moves the frame to a second position angularly spaced from and at greater distance from the spin axis than the first position. A processing chamber is mounted on the holding member and its orientation relative to the spin axis is the same in the first and second positions. Fluid is provided in the processing chamber. By accelerating the processing chamber to the first predetermined speed and decelerating below the first predetermined speed in a selected sequence, specific centrifugal force vectors are generated in the processing chamber that move the fluid and retain it in selected chambers. During this sequence, the fluid is metered, separated and delivered to a reduction area where measuring is performed.
