Abstract

See full text

An analysis apparatus is disclosed, which comprises guide rails for supporting a plurality of sample-containing reaction tubes in a straight row, a plunger for moving the reaction tubes supported on the guide rails in the direction of arrangement, a first rotary table for supporting a plurality of sample-containing reaction tubes along a circular line, and a motor for rotating the rotary table. Second rotary tables are disposed above the straight and circular arrangements of reaction tubes. These second rotary tables support at least two reagent distributors for distributing reagent into the reaction tubes. Each reagent distributor includes a reagent phial containing a reagent and a pump integral with the reagent phial for withdrawing the reagent in the reagent vessel. The pump has a nozzle through which the reagent is discharged. The rotary table is rotated by a motor such that the nozzle of a reagent distributor used for reagent distribution is brought to a position right above a pertinent reaction tube. The pump of the reagent distributor used for the reagent distribution is driven by a plunger.
