High performance system for the parallel and selective dispensing of micro-droplets, and transportable cartridge and dispensing kit using said system

摘要

This invention aims at allowing a consistent increase in the output of selective dispensing of micro-droplets, at making a spatial, targeted selectivity by distributing a predetermined reagent on the predetermined site, and at creating a multifunctional system, easy to adjust.;An example of dispensing system according to this invention consists of a substrate (2) covered by a membrane (3) and of means for deforming (65) the membrane at the right of each cavity formed in the substrate, and where the cavities, etched in a material constituting the substrate (2) in a matrix shape, appear in the shape of wells (10) crossing the substrate with lateral, continuous walls (11) of axial symmetry; each well opening on the upper surface and the lower surface of the substrate with respectively a feeding opening (12) and an ejection duct (14), the feeding opening showing an opening consistently higher than the opening (13) of the duct.;Application to the manufacturing of cartridges and of miniaturised kits in biochemistry and pharmacy, or also in cosmetics, in analytical instrumentation, in printing by inkjet or in the automobile electronics.
