ABSTRACT:
In an automatic chemical analyzer, a plurality of reagent containers are arranged annularly in a table and a reagent distribution nozzle unit is located between reaction cells and reagent containers and substantially at the center of an arcular array of container. In the nozzle unit, arm is secured to shaft which is vertically displaceable and rotatable. The arm is provided with a tiltable arm head and a nozzle for withdrawing a reagent from the reagent container is fixed to the arm head. The arm head and nozzle is tilted and a suction port of nozzle is shifted from a position over the reagent container to a position over draining groove, when the shaft is rotated.
