Abstract

A fluidics module (10) rotatable about a rotational center (52) comprises a first chamber (60) a second chamber (64) and a compression chamber (62). A first fluid channel (68) is provided between the first chamber (60) and the compression chamber (62) and a second fluid channel (74) is provided between the second chamber (64) and the compression chamber (62). The flow resistance of the second fluid channel (74) is smaller for a flow of liquid from the compression chamber to the second chamber than a flow resistance of the first fluid channel (68) for a flow of liquid from the compression chamber to the first chamber. Upon rotation at a high rotational frequency liquid is initially introduced from the first chamber (60) into the compression chamber (62) via the first fluid channel (68) so that a compressible medium is compressed within the compression chamber. Subsequently the rotational frequency is reduced so that the compressible medium within the compression chamber will expand and so that thereby liquid is driven into the second chamber (64) via the second fluid channel (74).
