Abstract:
An automatically analyzing apparatus, comprising:a plurality of reaction containers for reacting a sample with a reagent; and a reaction container washing unit for washing the reaction containers through a plurality of successive washing stations, said reaction container washing unit including: a first washing station for feeding a washing liquid from a washing station downstream of the first washing station into each of the reaction containers after a reacted content containing a reacted substance is discharged from the reaction container, so as to obtain a washing liquid having a concentration of the reacted substance (C1), a second washing station for discharging the washing liquid having the concentration (C1) from the reaction container into a second station reuse container belonging to the second washing station, and feeding a washing liquid from a washing station downstream of the second washing station into the reaction container so as to obtain a washing liquid having a concentration of the reacted substance (C2, wherein C21), a plurality of intermediate washing stations each for discharging a washing liquid having a concentration of the reacted substance one of (C2 . . . Cnâˆ’1, wherein n equals an integer) from the reaction container into a reuse container belonging to each intermediate washing station, and feeding washing liquid from a station downstream thereof into the reaction container so as to obtain a washing liquid having a concentration of the reacted substance one of (C3 . . . Cnâˆ’1), one of said plurality of intermediate washing stations being a latter stage washing station for discharging a washing liquid having a concentration of the reacted substance (Cnâˆ’1) from the reaction container into a latter stage reuse container belonging thereto, and feeding a pure washing liquid into the reaction container so as to obtain a washing liquid having a concentration of the reacted substance (Cn), and a final washing station for discharging a washing liquid having a concentration of the reacted substance (Cn) from the reaction container into a final station reuse container belonging thereto, wherein the washing liquid fed into the reaction container at each washing station is fed from the reuse container belonging to a washing station downstream thereof, and the concentration of the reacted substances (C1, C2, C3 . . . Cnâˆ’1, Cn) are successively lower.
