ABSTRACT:
A centrifugal analysis device is provided in which a plastic rotor has peripheral cells each containing a reagent. The rotor is configured such that sample fluid within a central receptacle is equally dispensed to each of the peripheral cells. An outlet orifice is positioned at a radial distance greater than the inlet orifice to each cell such that each cell is permitted (1) to be completely filled with fluid and (2) simultaneously such that all reactions take place at the same beginning point.
