Abstract

A fluidic module rotatable about a center of rotation includes a first compression chamber having a fluid inlet and a fluid outlet, a second compression chamber having a fluid inlet, a first fluid channel connected to the first chamber via the fluid inlet of the first chamber, and a second fluid channel connecting the fluid outlet of the first chamber to the fluid inlet of the second chamber. Due to rotation of the fluidic module a liquid may be centrifugally driven into the first chamber and the second fluid channel through the first fluid channel, and thereby a compressible medium may be entrapped and compressed within the second chamber. By lowering the rotary frequency and due to the resultant expansion of the compressible medium, liquid may be driven out of the second fluid channel into the first chamber, out of the first chamber into and through an outlet channel.
