Abstract
A device for mixing very small quantities of liquids comprises at least one mixing element with at least one inlet channel and at least one outlet channel; at least two microchannels issue from the inlet channel, all such issuing channels lying in a single branching plane. The microchannels are led to a confluence element in a plane which is rotated 90 degrees in relation to the branching plane. The mixer element is arranged in the planar surface of a substrate, the planar surface being hermetically sealed by a covering. The invention concerns a device for mixing liquids in which mixing is effected by the flow of the liquids to be mixed through narrow channels.
