A tip mounting position, an aliquoting position, a dispensing position, and a tip casting position are circumferentially arranged around a rotating shaft, and a plurality of aliquoting/dispensing mechanisms are circumferentially arranged corresponding to the plurality of operating positions around the rotating shaft. Each aliquoting/dispensing mechanism is provided with a nozzle lift mechanism and a nozzle mechanism that includes a nozzle lift mechanism and a nozzle portion. The rotating shaft is intermittently rotated to locate the aliquoting/dispensing mechanisms individually in the positions whereupon tip mounting, aliquoting, dispensing, and tip casting operations are performed continuously.
