Abstract:
1. An automated analyzer for performing a first processing operation to create a pretreated specimen by pretreating a specimen with a pretreatment solution in a first set of reaction cells and a second processing operation to create a reacted specimen by reacting the pretreated specimen with a reagent in a second set of reaction cells, said automated analyzer comprising: a turntable on which the first and second reaction cells are arranged annularly; controller for controlling rotation of the turntable; first aliquot dispenser for selectively pouring out either the pretreatment solution or the reagent into reaction cells positioned at a first position around the turntable; second aliquot dispenser for selectively performing dispensing of aliquots of the specimen into the first reaction cells or injection of aliquots of the pretreated specimen into the second reaction cells at a second position around the turntable; a stirrer for selectively performing stirring of the pretreatment solution and the specimen in the first reaction cells and stirring of the pretreated specimen and the reagent in the second reaction cells at a third position around the turntable; and measuring means instrument for measuring the reacted specimen; wherein said controller repeatedly performs a first control operation for rotating the turntable through a first angle in a first direction and then bringing the turntable to a halt and a second control operation for rotating the turntable through a second angle in a second direction opposite to the first direction and then bringing the turntable to a halt; wherein said second reaction cells are spaced by the second angle in the first direction from the first reaction cells; wherein the turntable is so rotated that the first and second reaction cells are halted at least in the first, second, and third positions by repetitive execution of the first control operation and the second control operation; and wherein said second aliquot dispensing means sucks the pretreated specimen from the first reaction cell when the first reaction cell containing the pretreated specimen is halted in the second position and pours out the sucked pretreated specimen into the second reaction cell when the second reaction cell is halted in the second position.
