Abstract: A magnetic stirrer is provided having a minimal overall height so that it is approximately plate-like and flat and its electrical stirring drive formed by magnetic coils is arranged with the driving ends of the magnetic coils approximately flush with the circuit board with the control circuit, wherein the axial dimension of the magnetic coils is smaller than its diameter. In addition, a cover made from non-ferromagnetic material, especially an adhesive film, which tightly seals the housing, is arranged over, and adhered to, the surface of the circuit board and the driving ends of the magnetic coils and lies in a common plane with an outer border of the housing.

Abstract: A laboratory apparatus, in particular a magnetic stirrer (1) or a shaker, has a receptacle (2) for a stand rod (3), the receptacle being provided in a separate stand-rod holder (4) which can be fastened to the laboratory apparatus in such a way that it is adjustable and can be fixed into position. As a result, the stand rod (3) can be fixed at various locations on the apparatus, so that each of the accessory devices connected to it, in particular sensors, dosing devices, or tubes, can be better fixed in their desired position. In addition, several stand-rod holders (4) with one stand rod each can be fastened at various locations on the laboratory apparatus at the same time, so that even in the case of complex experimental set-ups there are sufficient fastening options available for the accessory devices.
