Title
(EN) WASHING DEVICE AND ANALYZER
(JA) 洗浄装置および分析装置
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a washing device capable of reducing the amount of a washing liquid required for washing a cuvette, and to provide an analyzer.

SOLUTION: In this analyzer, since the volume of a washing nozzle occupied in the cuvette 21 is increased by thickening the walls of a supply nozzle 191 and a suction nozzle 192 both of which constitute the washing nozzle by making the wall cross-sectional areas S12 and S22 of both of the supply nozzle 191 and the suction nozzles 192 larger than the inner diameter cross-sectional areas S11 and S21, the occupying ratio of the washing liquid Ls in the cuvette 21 is reduced and the amount of the washing liquid required for washing the cuvette 21 is reduced.

【課題】キュベット洗浄のために要する洗浄液量を低減できる洗浄装置および分析装置を提供すること。
【解決手段】この発明にかかる分析装置においては、洗浄ノズルを構成する供給ノズル191および吸引ノズル192の壁断面積S12、S22を内径断面積S11,S21よりも大きくすることによって、供給ノズル191および吸引ノズル192の壁を厚くしてノズルがキュベット21内に占める体積を大きくしたため、キュベット21内において洗浄液Lsが占める割合を減らし、キュベット21洗浄のために要する洗浄液量を低減することが可能になる。
