Abstract

A device and a process for manipulation of a liquid, the ability of a liquid to flow from a first channel section in a second channel section being temporarily stopped by means of a capillary stop before it flows from the first channel section into the second channel section. Control which is accurate in time is easily enabled by the two channel sections being moved relative to one another for bridging or cancelling the capillary stop, especially being brought into contact.
