MICROMIXER, AND MICROFLUID CHIP

摘要

PROBLEM TO BE SOLVED: To provide a micromixer simple in constitution and capable of efficiently mixing two or more kinds of liquids, and a microfluid chip loaded therewith. SOLUTION: The micromixer includes fine flow channels through which first and second liquids are respectively allowed to flow and a mixing tank having the liquid injection port allowed to communicate with the fine flow channels provided to the bottom thereof and the liquid injection port is provided to the bottom at a position shifted from the center of the bottom. Further, the liquid injection port may be provided at a position shifted from the center line of the mixing tank. Furthermore, in the cross section along the horizontal direction of the internal space region surrounded by the inner wall of the mixing tank, the first distance up to the inner wall related to one direction and the second distance up to the inner wall related to the direction opposite to one direction may be made different on the basis of the passing position of the imaginary line upwardly extending from the center of the liquid injection port imaginarily.
