To provide a reaction treatment apparatus that can accurately stop a sample at a predetermined position of a temperature range.SOLUTION: A reaction treatment apparatus 30 comprises: a reaction treatment container 10 in which a flow channel 12 is formed; a liquid feeding system 37; a temperature control system 32; a fluorescence detector 50 which detects a sample 20 passing through a fluorescence detection region of the flow channel 12; a CPU36 which controls the liquid feeding system 37 based on a detected signal. When the sample 20 moves from a low temperature region to a high temperature region, the CPU36 instructs the liquid feeding system 37 to stop the sample 20 when predetermined first stand-by time has passed since a time point of the sample 20 passing through a fluorescence detection region detected by the fluorescence detector 50. When the sample 20 moves from the high temperature region to the low temperature region, the CPU36 instructs the liquid feeding system 37 to stop the sample 20 when a predetermined second stand-by time period, which is set independently of the first stand-by time period, has passed from the time point of the sample 20 passing through the fluorescence detection region detected by the fluorescence detector 50.SELECTED DRAWING: Figure 2 【課題】試料を温度領域の所定の位置に正確に停止させることのできる反応処理装置を提供する。【解決手段】反応処理装置３０は、流路１２が形成された反応処理容器１０と、送液システム３７と、温度制御システム３２と、流路１２の蛍光検出領域を通過する試料２０を検出する蛍光検出器５０と、検出された信号に基づいて送液システム３７を制御するＣＰＵ３６とを備える。試料２０が低温領域から高温領域に移動するとき、ＣＰＵ３６は、蛍光検出器５０により試料２０の蛍光検出領域の通過が検出された時刻から、所定の第１待機時間が経過したとき、送液システム３７に試料２０の停止を指示する。試料２０が高温領域から低温領域に移動するとき、ＣＰＵ３６は、蛍光検出器５０により試料２０の蛍光検出領域の通過が検出された時刻から、第１待機時間とは独立して設定された所定の第２待機時間が経過したとき、送液システム３７に試料２０の停止を指示する。【選択図】図２
