The invention relates to an arrangement and method for fluid rotation in the case of fluid transportation speeds with low Reynolds numbers, in particular for use in a two-layer chip system, and in the case of Reynolds numbers Re < 10 for three-dimensional hydrodynamic focussing, in particular for image-based throughflow cytometry. The object of the invention of specifying an arrangement and method for fluid rotation which permit the implementation of three-dimensional hydrodynamic focussing on just one two-layer chip system is achieved in that two or more channel segments are connected offset with respect to one other at their ends and arranged at an angle with respect to one another, as a result of which the through-flowing medium respectively experiences changes in direction which together bring about rotation of the medium about the axis in the direction of flow. |
