Abstract

L'invention concerne un dispositif de transfert de micro-quantités de liquide, comprenant au moins un élément de prélèvement et de transfert (1) d'une micro-quantité de liquide (6), des moyens étant prévus pour éliminer, après le transfert du liquide, des résidus (5) laissés par le liquide sur une surface (2) dudit élément, caractérisé en ce que lesdits moyens sont constitués d'une couche sacrificielle (3) formée sur ladite surface et destinée à être au moins partiellement éliminée sous l'action d'au moins un moyen (16) permettant de restituer ou de récupérer au moins une partie desdits résidus laissés par le liquide.L'invention concerne également des procédés de prélèvement de micro-quantités de liquide et un procédé de décharge.The invention relates to a device for transferring micro-quantities of liquid, comprising at least one element for collecting and transferring (1) a micro-quantity of liquid (6), means being provided for removing, after the transfer liquid, residues (5) left by the liquid on a surface (2) of said element, characterized in that said means consist of a sacrificial layer (3) formed on said surface and intended to be at least partially removed under the action of at least one means (16) making it possible to restore or recover at least a part of said residues left by the liquid. The invention also relates to methods of sampling micro-quantities of liquid and to a discharge method.
