Abstract:
An automatic immunoassay apparatus comprising:a reaction tube turret that rotates intermittently at a predetermined speed;a reaction tube holding portion including a plurality of reaction tube holders arranged in two rows composed of an inner row and an outer row along the periphery of an upper surface of said reaction tube turret;a reaction tube supplying means for supplying a reaction tube to and from a predetermined one of said reaction tube holders of said reaction tube holding portion;a reaction tube transfer means for transferring the reaction tube held by one of said reaction tube holders to another reaction tube holder while skipping a desired number of reaction tube holders;a sample dispensing means for dispensing a sample to the reaction tube;a particle supplying means for supplying particles to the reaction tube;a reagent dispensing means for dispensing a labeled reagent to the reaction tube;a washing means for separating bound particles from free particles;an assay reagent dispensing means for dispensing an assaying reagent to the reaction tube;an assaying means for assaying the amount of the labeling substance in a reacted reaction solution in the reaction tube; anda reaction tube discarding means for removing the assayed reaction tube from said reaction tube holding portion and discarding the thus removed reaction tube.
