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.

Dynamic braking centrifuge

Separation device and method for the fractionation and separation of finely divided solid particulate material suspended in a liquid are disclosed. The separation device comprises upper and lower portions which are joined together to form an inner cavity retaining liquid and a capillary gap which extends outwardly radially from said cavity. During rotation solid particles present in the suspending liquid pass outwardly along and/or become entrapped in the capillary gap(s).
