Claim Text:
1. A method for providing a homogeneous thoroughly mixed liquid comprising: providing a microfluidic element having a substrate and a channel structure, wherein the channel structure includes an elongate mixing channel and an output channel, wherein the mixing channel has a directly adjoining inlet opening and an outlet opening, the outlet opening being in fluid communication with the output channel, wherein the outlet opening is located closer to the middle of the length of the mixing channel than the inlet opening, and, wherein the mixing channel has a feed section between the inlet opening and the outlet opening and a complementary section, downstream from the outlet opening in the flow direction and opposite to the inlet opening; receiving in the mixing channel a flow of liquid exteriorly applied directly to the inlet opening; dissolving a reagent contained in the mixing channel; and exerting a force on the liquid in the mixing channel to: allow the liquid to flow into the output channel through the outlet opening of the mixing channel so that thorough mixing of the liquid and the reagent occur, and flow partial volumes from the feed section and the complementary section of the mixing channel through the outlet opening into the output channel such that mixing of the two liquid partial volumes is supported by exertion of the force on the liquid.
