STIRRER AND AUTOANALYZER USING THE SAME

摘要

<P>PROBLEM TO BE SOLVED: To provide a stirrer capable of more certainly stirring the whole of the reagent in a reagent container in a shorter time, and an autoanalyzer using the same. Ž<P>SOLUTION: A stirring shaft 2 with stirring blades 1 is rotationally driven not only to produce the circumferential flow of the stirring shaft 2 in the reagent containing magnetic particles 15 but also to discharge air in the reagent from the lower end of the air feed passage 2b provided to the stirring shaft 2 so as to pierce the stirring shaft 2 to produce the axial flow of the stirring shaft 2 in the reagent. The reagent is stirred by producing both of the circumferential flow of the stirring shaft 2 and the axial flow of the stirring shaft 2 in the reagent. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
