    摘要: The invention relates to a method for washing at least one cavity (20′) in a microfluidic component, the cavity (20′) containing a first liquid (F1) and at least one second liquid (F2) being supplied to the cavity (20′) for washing.According to the invention an air bubble (L) is supplied to the cavity (20′) before the washing liquid (F2) is introduced.The air bubble (L), which acts as a virtual barrier layer between the first liquid (F1) and the washing liquid (F2) that follows it enables the washing efficiency to be increased considerably. Overall, this method leads to a saving in washing liquid (F2) and washing time.Moreover, a microfluidic component is proposed for carrying out the method.

    摘要: 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.

    摘要: The invention relates to a container (1) for a fluid for metering a reagent into a microfluidic system. The container comprises a chamber (4) and a first film (3) which seals off the chamber (4) so that the fluid is encapsulated in the chamber. Advantageously, the first film (3) is an aluminium sealing film. A second film (7) is sealingly arranged on the first film, for example by adhesive bonding of the film layers. The films differ in their tear strength such that when pressure is applied simultaneously to both films the first film tears while the second film deforms elastically and/or plastically. By tearing the first film a connection is produced between the container chamber and an inlet channel so that a fluid contained in the chamber flows into the microfluidic system.
