A method and apparatus are provided for accurately preparing centrifuged fluid samples for microscopic analysis. In the method a centrifuged fluid specimen contained in a sample tube of known volume and dimensions located in motor (W) driven sample tube cassette carousel (V) has the level of fluid specimen in the sample tube detected therein with a sensing duel pipette tube (D6). This level is used in calculating the total volume of fluid specimen in the sample tube with the computer (D). Thereafter, an amount of fluid specimen sufficient to leave a predetermined volume percentage of fluid specimen in the sample tube is decanted. Next the sample tube is agitated to resuspend the sediment that had been concentrated in the centrifuged fluid specimen. |
