摘要:
The present invention relates to a microstructure arrangement for the bubble-free filling with a liquid of at least one system for draining off liquids. The arrangement has an inlet for the arrangement to be connected to a system for the supply of liquids and at least one outlet for the arrangement to be connected to the at least one liquid-discharging system. The arrangement has a transition region, through which the liquid can be transported from the inlet to the at least one outlet. At a start of the transition region, at least one first microstructure element for producing a point with increased capillary force is provided, in order to achieve gap-free wetting of the areas bounding this point with increased capillary force, in particular side walls, a cover and/or a bottom.
摘要:
A microstructured separating device, especially for separating liquid components from a particle-containing liquid, comprising the following features: at least one transport channel for transport of the liquid in a given transport direction; at least one separating area at a branch point of the transport channel which is adjoined by a side channel through which a partial flow of the liquid from the transport channel is diverted; a microstructure in the separating area which keeps larger particles of the liquid out of the separating area and which slows down the transport of smaller particles in the separating area.

摘要:
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.
摘要:
A device and a process for testing a sample liquid wherein the sample liquid flows laminarly by capillary forces over a flat side of a channel to completely filling a reaction area which has a soluble and/or reacting reagent on the flat side and defines a reaction volume of the sample liquid, the reaction volume being temporarily stopped in the reaction area for dissolving or reacting at least 90% of the reagent in the defined reaction volume of the sample liquid, and at least 90% of the dissolved reagent or a reaction product, after stopping, flows together with the reaction volume into the test area which is formed by the channel downstream of the reaction area, the sample liquid flowing with an at least essentially straight liquid front and/or at least essentially without a change in the flow cross section from the reaction area into the test area.
摘要:
A microstructured platform for manipulating a wetting liquid including at least one cavity and a channel system for transporting the liquid. At least some of the channels of the channel system are made as capillaries which have a dimension in the millimeter range or less in at least one direction transverse to the transport direction of the liquid. The platform also includes at least one other microstuctured element disposed in the transport path of the liquid. The microstructured element may be in the form of a fluidic switch, metering means, separating device, or a region for holding together a limited amount of liquid. The structure facilitates or enables the manipulation of liquids when only a small amount of liquid is available and extensive analyses are to be performed with the liquid.

摘要:
A membrane structure for gas separation, a degassing device having such a membrane structure, and also method for production of the same are proposed. A porous carrier layer is joined flat to a thin polymer membrane, in particular made of amorphous PTFE. In particular, the polymer membrane is produced on or from the carrier layer. This makes possible a simple and inexpensive structure and also an effective gas separation. Particularly preferable, the polymer membrane is formed by applying a polymer solution in the liquid state to the carrier layer and drying it.
摘要:
A process and a device for determining the viscosity of a fluid are proposed. Very simple and accurate determination is enabled in that the magnetic particles in the fluid are set into vibration by a magnetic field which varies over time. A measurement of the amplitude and/or phase of particle vibration is used to determine the viscosity or an associated quantity, such as the coagulation of blood or the glucose content.
