Abstract

A substrate of a lab-on-a-chip system has two adjacent recesses, one serving as a flow channel and the other one being filled with an elastomer compound. In a first state, the elastomer compound and the substrate delimit the flow channel in a section. In a second state, the elastomer compound takes up the space in the recess in the substrate along a cross-section of the flow channel, thereby completely closing the flow channel. The substrate and the elastomer compound may be produced by injection molding techniques.
