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.

[ We claim:] [1.] A device for mixing liquids, wherein mixing is effected by the flowing of the liquids through narrow channels, said device comprising:at least one mixing element having at least one inlet channel and at least one outlet channel, wherein said mixing element is arranged on at least one substrate having planar surface;at least two microchannels issuing from said inlet channel, said at least two microchannels lying in a same branching plane;a confluence element being connected by a connection to said microchannels, wherein the connection effects a 90.degree. rotation of the inflow of the liquid relative to said branching plane as the liquid flows from said microchannels to said confluence element;said at least one outlet channel being connected to said confluence element; anda covering hermetically sealing the planar surface of said at least one substrate to cover the mixing element. [2.] The device according to claim 1, wherein said at least one outlet channel is in a plane parallel to a plane of the inlet channels; and, said device further comprising one or more opening through which said at least one outlet channel is fed back into said plane of said at least one inlet channel.
