Abstract

La présente invention concerne un dispositif de positionnement de cellules d'échantillons. Dans ce dispositif, des cellules 42 et 43 destinées à être analysées alternativement par un faisceau optique et fournissant un faisceau de sortie 25 par une fenêtre 73 sont montées sur un support 41. Le support est entraîné en un mouvement de va-et-vient selon un axe vertical pour exposer alternativement les cellules. La vitesse du mouvement de va-et-vient est choisie pour éviter toute cavitation dans les échantillons et un agencement 61, 63 de déplacement sinusoïdal est prévu. Applications aux appareils d'analyse de fluorescence optique.
