Abstract: The invention relates to a device for applying a plurality of microdroplets to a substrate (65) comprising a plate (50) provided with a plurality of bore holes (51) and a bottom (52) which is connected to said plate (50), and is provided with a plurality of channels (53). The device is characterized in that each bore (51) of the plate (50) is assigned to a single channel (53) of the bottom (52). The invention also relates to a method for producing this device, the use of this device for applying a plurality of microdroplets to a substrate (65), as well as a method for applying a plurality of microdroplets to a substrate (65).

Abstract: The invention relates to a multi-duct fluid dispenser for withdrawing liquid (14) from a plurality of cavities (12) formed in a reservoir platter (10) and spraying it onto a receiving platter (16). It comprises: a plurality of flexible ducts (26) arranged in a convergent bundle, the first ends of which are intended to be immersed in said cavities and the second ends of which are assembled in a miniaturized array, means of filling said ducts, from their first ends, with the liquid contained in the cavities, and means of expelling a drop of liquid from the second end of each duct toward the receiving platter. The ducts are formed in a plurality of flexible plates (18) joined together by their part (24) that comprises the second ends of the ducts. They are each formed of two polymer sheets (34, 36) sealed together and of which at least one is endowed with an array of convergent grooves forming the ducts.
