Abstract

Procédé et dispositif pour la sélection de cellules vivantes. Le procédé consiste en un balayage de chaque cellule à étudier par un faisceau lumineux 4 reçu par un photomultiplicateur 6. Celui-ci envoie des informations à un sélecteur agissant sur des micro-soupapes électromagnétiques 10, 11 branchées sur des dérivations respectives 14, 15 d'un canal 3 dans lequel circule le liquide contenant les cellules. Application à la microbiologie.
