| 20080257754 | METHOD AND APPARATUS FOR ENTRY OF SPECIMENS INTO A MICROFLUIDIC DEVICE - A microfluidic device for analyzing biological samples is provided with a sample inlet section including an inlet port, a capillary passageway communication with the inlet port and with an inlet chamber. The inlet chamber includes means for uniformly distributing the sample liquid across the inlet chamber and purging the air initially contained therein. | 10-23-2008 |
| 20090004059 | METHOD AND APPARATUS FOR PRECISE TRANSFER AND MANIPULATION OF FLUIDS BY CENTRIFUGAL AND OR CAPILLARY FORCES - A micro-liter liquid sample, particularly a biological sample, is analyzed in a device employing centrifugal and capillary forces. The sample is moved through one or more sample wells arrayed within a small flat chip via interconnecting capillary passageways. The passageways may be either hydrophobic or hydrophilic and may include hydrophobic or hydrophilic capillary stops. | 01-01-2009 |
| 20090074626 | Microstructured device for removable storage of small amounts of liquid and a process for removal of the liquid stored in this device - Microstructured device for removable storage of small amounts of liquid with the following features: the device has a carrier; the device has a first cavity with at least one first section for storage of a small amount of liquid; the first section of the first cavity is molded into the carrier; the first section is closed with a cover element and a blocking element; the device has a means for transmission of a force from the cover element to the blocking element which destroys the connection between the blocking element and the carrier or destroys the blocking element itself so that the amount of liquid can be removed from the first section of the cavity. | 03-19-2009 |
| 20090184175 | DISCHARGE DEVICE AND METHOD FOR EVAPORATING A LIQUID AND EVAPORATOR - A discharge device, an evaporator and a method for evaporating a liquid to the atmosphere in which the liquid is supplied to an evaporation surface only by a capillary. | 07-23-2009 |
| 20100126927 | DEVICE FOR THE INTAKE OR MANIPULATION OF A LIQUID - A device for the intake or manipulation of a fluid, in particular, a liquid, and a method for the production of a device of this type in which a flat, non-preformed covering film is laminated onto a carrier, a three-dimensionally shaped or convex chamber wall being formed solely by means of the laminating process. The chamber wall which forms a boundary of a chamber for the fluid is partially deformable. The device is simple to produce and can be used universally. | 05-27-2010 |
| 20100172801 | METHOD FOR UNIFORM APPLICATION OF FLUID INTO A REACTIVE REAGENT AREA - Analytical results obtained with microfluidic devices are improved by providing structural features in areas containing dry supported reagents, the structural features directing the flow of a sample over the area in a predetermined uniform manner and facilitating the purging of air. | 07-08-2010 |

| 20110088786 | METHOD FOR MANIPULATING A LIQUID ON A FABRICATED MICROSTRUCTURED PLATFORM - A method for manipulating a first liquid within a device including fabricated microstructures for transporting the first liquid through a system of capillary channels and cavities with a closed configuration. 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 |
| 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 |
