The invention relates to a device for removing and depositing droplets of at least one liquid, a method of using the device and a servo system for said method. The inventive method can be used to remove and deposit droplets of liquid while preventing any contact with the ambient air before the liquid is deposited, using a device which can be closed and which can be supplied to the user in the form of a prefilled cartridge. In the preferred embodiment of the invention, the device for removing and depositing droplets (100) of at least one liquid (32) comprises: an outer tube (101) with an opening (107) at one of the ends thereof, a flange (109) defining the opening (107); a rod (111, 211, 221) which can slide inside the outer tube (101); an inner volume (117) between the rod (111, 211, 221) and the outer tube (101); a capillary-dimensioned open hole (119) in the wall of the outer tube (101); and a closure element (113, 213) which seals the above-mentioned opening (107) and which is connected to the rod (111, 211, 221). According to the invention, when the rod (111, 211, 221) is in the forward end position, the closure element (113, 213) rests on the flange (109) and, in this way, hermetically seals the opening (107), and, when the rod is not in the aforementioned end position, a capillary-dimensioned passage (115) communicates the inner volume (117) with the exterior.

L'invention propose de réaliser le prélèvement et le dépôt de gouttelettes de liquide en évitant tout contact avec l'air ambiant avant le dépôt du liquide en réalisant un dispositif qui peut se fermer, et qui peut être fourni à l'utilisateur sous forme d'une cartouche pré-remplie. Selon un mode de mise en .oelig.uvre préféré, le dispositif de prélèvement et dépôt de gouttelettes (100) d'au moins un liquide (32), comportant un tube externe (101) portant une ouverture (107) à une de ses extrémités, un rebord (109) délimitant ladite ouverture (107), une tige (111, 211, 221) pouvant coulisser à l'intérieur dudit tube externe (101), un volume interne (117) compris entre ladite tige (111, 211, 221) et le tube externe (101), un orifice (119) de dimensions capillaires ouvert dans la paroi dudit tube externe (101), et un élément de fermeture (113, 213) de ladite ouverture (107) relié à ladite tige (111, 211, 221). Selon l'invention, lorsque ladite tige (111, 211, 221) se trouve dans une position d'avancée extrême, ledit élément de fermeture (113, 213) s'appuie sur le rebord (109) et ferme ainsi hermétiquement ladite ouverture (107) et, lorsque cette tige est hors de cette position extrême, un passage (115) de dimensions capillaires met le volume interne (117) en communication avec l'extérieur.
