它提出了一种用于微型和毫升的反应容器的液体样品混合的马达驱动的搅拌器和搅拌器和Rührerblock的适配器。 所述适配器（1）装有搅拌器耦合（4），通过该适配器（1）与所述搅拌器（8）是可连接的，并且可以被驱动旋转，用搅拌棒容器（2），在其中一个端部 在轴向方向上，其中，所述搅拌杆容器（2）基本上同轴到适配器的旋转轴线（1）对准搅拌棒被插入搅拌棒（3）（3），其中，所述搅拌杆（3）由旋转适配器（1）在 一个摆动运动可以被设置，使得搅拌杆（3）同时执行围绕其自身的轴线关于非恒定的旋转轴的第一旋转运动和第二旋转运动。

It is proposed an adapter for a motor-driven stirrer and stirrer and Rührerblock for mixing liquid samples in micro and milliliter reaction vessels. The adapter (1) is equipped with a stirrer coupling (4) via which the adapter (1) with the stirrer (8) is connectable and can be driven in rotation,
with a stirring rod receptacle (2) into which one end of a stirring rod (3) is insertable in the axial direction, wherein the stirring rod-receiving (2) the stirring rod (3) aligned substantially coaxial with the axis of rotation of the adapter (1), wherein the stirring rod (3) by rotating the adapter (1) is set into a tumbling motion, so that the stirring rod (3) performs a first rotational movement around its own axis and a second rotation movement about a non-constant rotational axis simultaneously.
