Abstract

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.
