Abstract

A microvalve for controlling fluid flows, and a sealing device for sealing cavities in a microfluidic system, particularly in a lab-on-a-chip system, and a method for the production thereof. A sealing surface of a valve body, or a sealing element, respectively, rests on a sealing surface of a substrate and is pressed against the sealing surface of the substrate in a fluid-tight manner by means of a clamping element. The clamping element and/or the valve body, or the sealing element, respectively, are at least partially elastic.
