A sample holder includes sample carrier and sealing foil thermally sealing microfluidic sample carrier cavities. The sealing foil has a sealing layer connected with the sample carrier. Sealing layer softening temperature is near sealing temperature of the sealing layer during sealing. The sealing foil outer layer use temperature is greater than sealing heating temperature and greater than or equal to sealing temperature. The sealing foil includes a height equalizing layer having softening temperature below sealing heating temperature. The equalizing layer is ductile at temperature less than or equal to sealing heating temperature and greater than or equal to sealing temperature. A sealing foil decoupler layer, at layer temperature less than or equal to sealing heating temperature or greater than or equal to sealing temperature, is stiffer than the equalizing and sealing layers. The equalizing layer is between outer and decoupler layers and sealing layer is outwardly of decoupler layer.

A fluidic module includes first and second measuring chambers, first and second fluid inlet channels connected to the first and second measuring chambers, respectively, and first and second fluid outlet channels connected to the first and second measuring chambers, respectively. Upon rotation of the fluidic module about a center of rotation, liquids are centrifugally driven into the first and second measuring chambers via the first and second fluid inlet channels, respectively, so that compressible media previously present within the first and second measuring chambers are compressed by the liquids driven into the first and second measuring chambers, respectively. Upon a reduction of the rotational frequency and upon an expansion, resulting therefrom, of the compressible media, the liquids present within the first and second measuring chambers are driven out of same via the first and second fluid outlet channels, respectively.
