20120118392 | PLASMA SEPARATION RESERVOIR - The invention relates to a microfluidic apparatus for producing a volume flow that is uniform over time in a metering process. In various solution processes or reaction processes it is essential to have a specified given volume flow or mass flow of fluid available to ensure reliable dissolution of the reagent or ensure that the reaction takes place. In microfluidic apparatus in which separation of particles from a fluid, particularly blood, is carried out through a membrane, the volume flow through the membrane decreases continuously. In order to achieve a uniform volume flow during metering, it is envisaged that first of all a reservoir is filled from a first channel, so that the contents of the reservoir can then be fed to the metering process by opening a fluid stop. The emptying of the reservoir takes place with a uniform volume flow of 0.05 microlitres per second to 10 microlitres per second. | 05-17-2012 |

20110135546 | MICROFLUIDIC FOIL STRUCTURE FOR METERING OF FLUIDS - The invention relates to a microfluidic device for metering liquids into a microfluidic network. The microfluidic channels or chambers are at least partly formed by the introduction of suitable structures into a film above the substrate carrier, so that at least some of the flow of fluid through the network takes place above the plane of the substrate. In order to form a stable channel structure or chamber structure in the film, it is envisaged that in the edge zone between the unattached and attached portions a wedge of material is formed by the viscous flow of the film material as the film is bonded to the substrate, this wedge forming a transition between the chamber wall and the substrate and raising the chamber wall above the plane of the substrate. In one method of producing a finished microfluidic structure a flat planar film is laminated onto a flat sheet-like substrate. During the lamination a mask having at least one recess or opening is pressed onto the film and onto the substrate under pressure and/or under the effect of heat. The film is thereby brought to a temperature at which there is a viscous flow of film and/or substrate medium into the region of the recess or opening, so that a wedge of material is formed and the film bulges up in the region of the recess to form a chamber. The invention further relates to methods of metering at least one liquid in a microfluidic network, in which a capillary stop is overcome by actuating the film, the film being wetted as the capillary stop is removed. | 06-09-2011 |

The method including transporting the first liquid through the system by capillary force only, stopping a flow of the first liquid temporarily at a capillary stop, switching on the flow of the first liquid after a desired stop time is elapsed, adjusting the stop time of the first liquid by a length and a cross-section of the control capillary between a beginning of the control capillary and its end at the capillary stop, metering the first liquid to be manipulated, and holding a metered amount of the first liquid during the stop time within a cavity. | 04-21-2011 |
