Patent Abstract

The invention relates to a device for mixing liquids in a microchannel (6) by means of magnetic particles (9) with a permanent magnet (1), which is moved by drive means such that the magnetic particles (9) move transversely to the length of the microchannel (6), which is characterized in that it comprises two holders (2) for receiving at least one permanent magnet (1) each, which are connected to drive means that enable movement of the permanent magnets (1, 1a), wherein at least one microchannel (6) is arranged between the holders (2) such that a liquid flow contained therein extends between the holders (2) and in which the drive means enable movement of the permanent magnets (1, 1a) out of the plane of the flow direction of the liquid.
