Abstract: A device and a method are proposed for actuating a carpule, in which a piston is displaced in the carpule by means of a ram that is telescopically extensible by rotation, and in this way a liquid medicament formulation is expelled. For carrying out different processes, different operating movements are provided, particularly the operation of an operating element in different directions and/or the operation of different operating elements. This promotes simple, intuitive and safe operation.

Abstract: Process for joining a foil or a membrane. The invention relates to a method for joining at least one foil-like or membrane-like part to a structural part (9), wherein the foil-like or membrane-like part is separated by means of a tool (2) from a semi-finished product (3) and is held on the tool (2) by applying a reduced pressure, and wherein the foil-like or membrane-like part is placed on the structural part (9), and is in turn held on this (9) and joined to this (9) by applying a reduced pressure. By means of the method a precise, reliable and readily automatable joining of a foil-like or membrane-like part to a structural part (9) is possible. A device (1) is also proposed, with which the method according to the invention can readily be carried out.

Abstract: 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.

Abstract: A device and a process for manipulation of a liquid, the ability of a liquid to flow from a first channel section in a second channel section being temporarily stopped by means of a capillary stop before it flows from the first channel section into the second channel section. Control which is accurate in time is easily enabled by the two channel sections being moved relative to one another for bridging or cancelling the capillary stop, especially being brought into contact.

Abstract: A sampling device and a system for testing of sample liquid are proposed. Very simple and prompt testing of the sample liquid is enabled in that the sampling device has a reservoir for the dilution liquid and that the taken-up sample liquid can be delivered by the dilution liquid directly to the testing area.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a device for the regulation of a plasma impedance in a vacuum chamber, wherein at least one electrode is connected to an AC generator. This AC generator is a free-running [oscillator], whose frequency adjusts to the resonance frequency of the load upon which it acts. This load comprises fixed circuit elements and a variable plasma impedance. If the plasma impedance is changed, with it the resonance frequency is also changed. The plasma impedance can thus be varied by acquisition of the resonance frequency and by presetting of a reference frequency value, for example thereby that the voltage, the current, the power or the gas inflow is varied as a function of the difference between resonance frequency and reference frequency value.
