Abstract

L'invention concerne un dispositif pour former et séparer une goutte dans un courant en écoulement, et il comprend un moyen pour former un courant fluide dans l'air. Selon l'invention, le dispositif comporte un moyen d'application 66, 68 communiquant avec le courant 46 dans l'air en un premier emplacement 64 et appliquant un signal électrique ou de l'énergie rayonnante au courant fluide 46 dans l'air au premier emplacement 64 pour perturber le courant et créer la goutte 70. L'invention s'applique notamment à la biologie et plus particulièrement aux examens du sang.
