  • Device for removing and depositing droplets of at least one liquid, method of using the device and servo system for said method
    Publication number: 20070025880
    Abstract: The invention proposes the drawing and deposition of liquid droplets while preventing any contact with the ambient air before the liquid is deposited, by providing a device which can be closed, and which can be supplied to the user in the form of a pre-filled cartridge. In a preferred embodiment of the invention, the device for drawing 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 said outer tube (101), an inner volume (117) between said rod (111, 211, 221) and the outer tube (101), a capillary-sized open port (119) in the wall of said outer tube (101), and a closure element (113, 213) for closing said opening (107), connected to said rod (111, 211, 221).

  • High performance system for the parallel and selective dispensing of micro-droplets, and transportable cartridge and dispensing kit using said system
    Patent number: 6833112
    Abstract: 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.
