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.

Device and method for actuating a carpule

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 (), wherein the foil-like or membrane-like part is separated by means of a tool () from a semi-finished product () and is held on the tool () by applying a reduced pressure, and wherein the foil-like or membrane-like part is placed on the structural part (), and is in turn held on this () and joined to this () 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 () is possible. A device () is also proposed, with which the method according to the invention can readily be carried out.

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.

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.

Sampling means and system for testing a sample liquid

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.
