<p><P>PROBLEM TO BE SOLVED: To provide an autoanalyzer which can prevent the occurrence of erroneous measurements and a decrease in measurement accuracy due to a residue of waste liquid, thereby reducing a running cost. <P>SOLUTION: An autoanalyzer includes: a suction tube which is provided with a suction opening at a tip thereof and is for discharging waste liquid from the inside of a reaction container to outside; a supply tube which is provided with a supply opening at a tip thereof and is for supplying washing liquid from the outside into the inside of the reaction container; a suction tube drive unit which moves the suction tube so that the suction opening reciprocates between a position above the reaction container moved to a washing position and a position near the bottom of the reaction container; a suction operation unit which suctions the waste liquid from the suction opening moved to the position near the bottom; a supply tube drive unit which moves the supply tube so that the supply opening reciprocates between a position above the reaction container after the waste liquid has been suctioned and a position near a liquid surface which is closer, from above, to the liquid surface before the waste liquid has been suctioned; and a supply operation unit which supplies the washing liquid to the supply opening moved to the position near the liquid surface. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
