Method for the contactless automatic mixing of a liquid reaction mixture in an analysis unit, in which the reaction mixture is located in a vessel accessible from above through an opening, by means of a gas jet escaping from an outlet opening of a mixing element, a rapid, effective and reliable non-invasive thorough mixing of the liquid is achieved by the mixing element being lowered at the start of the mixing operation in the direction of the liquid surface and the lowering movement being stopped in a bottom end position in which the mixing element projects into the vessel, but does not touch the liquid surface, the gas jet is switched on during the lowering of the mixing element, the gas jet is so aligned that it brings about an asymmetrical lowering of a part of the liquid surface in the vicinity of the vessel wall, and the gas jet has a rotational component of motion so that the lowered part of the liquid surface is set in rotation about the axis of the vessel.

A method for contactless automatic mixing of a liquid reaction mixture in an analysis unit, said method comprising the steps of: providing the liquid reaction mixture in a vessel having an opening at an upper portion thereof; providing a mixing element having at least one outlet opening therein, with a gas jet escaping from said outlet opening; lowering the mixing element through the opening in the vessel toward a surface of the liquid, until a bottom end of the mixing element projects into the vessel, but does not touch the surface of the liquid, wherein said outlet opening of said mixing element is configured so that the gas jet escaping therefrom asymmetrically lowers a portion of the liquid such that a portion of the surface of the liquid adjacent a vessel wall is lowered to form a depression having a deepest point, and wherein said gas jet includes a rotational component of motion, such that the deepest point of the depression moves laterally along the vessel wall about a longitudinal center line of the vessel.
