Abstract
A centrifuge for separating constituents of fluids, diluting the constituents and inoculating a reagent includes a spinning assembly for spinning a processor member. The processor member includes fluid and diluent compartments, separation chambers for a fluid and for a diluent, a mixing chamber, and a reagent chamber. The fluid compartment is in communication with the fluid separation chamber by a first passage. The diluent compartment and diluent separation chamber are communicated by a second passage. The first and second passages are oriented such that centrifugal force moves the fluid and diluent through the first and second passages into the respective chambers. The chambers are aligned to prevent outflow under the influence of centrifugal force but to allow outflow into measuring passages upon braking the spinning of the processor member. Spinning the processor member after braking generates a centrifugal force moving the fluid and diluent through the measuring passages into a mixing chamber. Braking the spinning of the processor member again applies a braking force on the mixed fluid and diluent moving this mixture into the reagent chamber.
