Abstract

L'invention concerne un système de réaction chimique pour l'analyse d'échantillons en faisant réagir l'échantillon avec un réactif chimique à une température prédéterminée. Selon l'invention, un échangeur de chaleur 60 est prévu sur la cellule de réaction 10 pour établir la température de la cellule. Le réactif 24 est pompé dans la cellule à travers un conduit 32, et une partie du conduit 32 est enroulée autour de la cellule de réaction 10 en contact avec l'échangeur de chaleur 60 pour préchauffer le réactif dans le conduit avant qu'il ne soit pompé dans la cellule 10. L'invention s'applique notamment aux analyses du sang et de l'urine.
