Abstract: The invention relates to a cooling device (1) for cooling components (101), comprising a baseplate (2) which can be heat-conductively connected to a component (101) to be cooled, a deflection region (3), an intermediate region (4) between the baseplate (2) and the deflection region (3), and a cooling element (5), which is formed in a meandering shape and has multiple central segments (51) and multiple deflection segments (52), wherein the central segments (51) each extend from the baseplate (2) to the deflection region (3), wherein the deflection segments (52) each create a change of direction within the baseplate (2) and within the deflection region (3) and connect two respective central segments (51) to one another, wherein the cooling element (5) is filled with a working material, which is simultaneously gaseous and liquid in the cooling element (5), and wherein the central segments (51) have a plurality of channels (53).

Abstract: A system for transferring a sample into a microfluidic system, including a sample loading chamber, wherein a first sub-volume of the sample loading chamber is separated from at least one second sub-volume of the sample loading chamber by a filter module. The first sub-volume forms a pressure chamber provided for the loading of the sample, and there is at least one second sub-volume for providing the microfluidic system with the sample.
