摘要： A device for applying microdroplets to a substrate includes a dosing head having a nozzle orifice and a liquid storage area in fluid communication with the orifice. A drive applies an acceleration to the dosing head. A quantity of liquid in the storage area cannot follow the acceleration due to its inertia. This inertia causes microdroplets to be driven out of the nozzle onto the substrate. In one embodiment, the dosing head includes a plurality of nozzle orifices each having an associated liquid storage area, so that a plurality of different analytes are deposited on the substrate.

摘要： A fluid management apparatus includes a substrate having a first surface and a second surface opposite to the first surface. A plurality of fluid inlets, which are preferably media reservoirs, are formed in a first pattern in the first surface of the substrate. A plurality of fluid outlets, which are preferably nozzles, are arranged in a second pattern, which is different from the first pattern, in the second surface of the substrate. A plurality of fluid ducts formed in the substrate for connecting respective fluid inlets with respective fluid outlets are provided so that a format conversation from the fluid inlets to the fluid outlets is effected. The fluid outlets have opening cross-sections smaller than that of the fluid inlets. Furthermore, the fluid inlets may be arranged in the raster scheme of microtiter plates.

摘要： A volume sensor-free microdosing device comprises a pressure chamber which is at least partly delimited by a displacer, an actuating device for actuating the displacer, the volume of the pressure chamber being adapted to the changed by actuating the displacer, a media reservoir which is in fluid communication with the pressure chamber, an outlet opening which is in fluid communication with the pressure chamber, and a control mechanism. The control mechanism drives the microdosing device in such a way that a small change of volume of the pressure chamber volume is effected per unit time by a movement of the displacer from a first position to a predetermined second position, the second position of the displacer defining a larger volume of the pressure chamber than the first position, so as to suck a fluid volume into the pressure chamber, and that, in a second phase, a large volume change of the pressure chamber volume is effected per unit time by a movement of the displacer from the second position to the first position, so as to eject a defined fluid volume from the outlet opening in this way.

摘要： A device for device for applying a plurality of microdroplets onto a substrate has a plurality of nozzle orifices in a dosing head. In addition to walls for defining a liquid column of a medium to be dosed on each nozzle orifice, a pressure chamber is provided, which is adapted to be filled with a buffer medium and which is arranged in such a way that said buffer medium can simultaneously be used for applying a pressure to the liquid-column ends which are spaced apart from the nozzle orifices. A pressure generator is provided for applying a pressure to said buffer medium in such a way that a plurality of microdroplets will simultaneously be applied onto the substrate through said plurality of nozzle orifices. Finally, liquid reservoirs for the media to be dosed, which are in fluid communication with the liquid columns on the nozzle orifices are provided.
