Finally in the fifth step, magazine and molded part are demolded simultaneously as one magazine/molded part composite.

Abstract: The invention relates to a method for quantitatively and/or qualitatively detecting layer thicknesses of biological or chemical molecules by means of ellipsometric measurements. Said molecules are deposited on at least one metal layer by virtue of interactions with a gaseous or liquid medium, whereby said metal layer is provided with an immobilisation layer. A method that can be carried out quickly is provided by including the surface plasmon resonance. Said method is provided with a significantly greater detection sensitivity and can be used not only for qualitatively detecting layers. According to the inventive method, the angle of incidence and/or the frequency of the electromagnetic radiation which is used for the ellipsometric measurements is/are adjusted in such a way that a surface plasmon resonance is produced in the metal layer. The detection sensitivity (? cos ?)/(thickness of the layer to be detected) is adjusted by means of the thickness of the metal layer.

Abstract: The invention relates to a micromixer for mixing at least two fluids that react to form precipitations or suspensions. The micromixer comprises a first channel for supplying a first partial flow (6) and a second channel for supplying a second partial flow (7). These flows empty into a mixing and reaction area (10) via narrow entrance gaps (19, 20) and leave the mixing and reaction area (10) via an outlet channel (11). The invention is characterized in that a reverse flow prevention is placed between the mixing and reaction zone (10) and at least one channel that supplies a partial flow (6, 7, 37).

Abstract: The invention relates to a device for drawing a sample and analyzing body fluids, and to a corresponding method. The device comprises a handle (1), which accommodates a pneumatic drive device, and a sensor unit (2) that contains a microneedle (3) on an elastic membrane (4) and at least one sensor system (5). The handle (1) and the sensor unit are detachably connected to one another, and the pneumatic drive device interacts with the sensor unit (2) in such a manner that the drive device exerts pressure onto the elastic membrane (4) so that the microneedle (3) pierces the surface of the skin in order to draw body fluid. During the ensuing decreasing pressure, the elastic membrane (4) returns to its original shape, and body fluid is suctioned, due to the resulting underpressure, from the location of piercing and into the interior of the sensor unit (2) to the at least one sensor system (5).

Abstract: Static lamination micro mixer comprising at least one slotted plate having slot openings and an aperture plate having aperture slots arranged above the slotted plate.

Abstract: Known static micromixers that work according to the principle of multilamination allow for a rapid mixing by diffusion. The invention provides a means for substantially increasing the throughput of known micromixers. To this end, the inventive micromixer for mixing two or more reactants comprises microstructures that define mixer cells. Each of said mixer cells is provided with a feeding chamber which adjoins at least two groups of digital channels. Said channels intermesh with the digital channels of the groups adjoining the feeding channels in a comb-like manner, thereby producing mixing zones]. Outlet ports are located above said mixing zones, said outlet ports extending perpendicularly to the digital channels and discharging the product. The inventive micromixer is especially useful for the large-scale production of mixtures, dispersions and emulsions.

At least one cassette acts as a base plate cassette wherein the microcomponents are arranged on a base plate acting as a component carrier. At least one joint assembly step is carried out, wherein two cassettes are respectively placed opposite each other and all microcomponents in the joined cassettes are simultaneously assembled to form sub-assemblies or component units. The component carriers of the cassettes are subsequently withdrawn. During assembly, the microcomponents can also be held in a rotationally secure position.
