ABSTRACT:
A magnetic stirrer (1) has a two-part housing (2), wherein the lower part (3) contains a drive motor (5) and its controlling, while the upper part (4) forms the mounting surface for a stirring container that holds the stirring magnet, and wherein the separating surface of the two parts (3) and (4) runs approximately horizontal when in the working position. The upper part (4) of this housing (2) is made of glass and the edge (8) of this upper part (4), when in its working position, is tightly pressed against an opposing surface (9) of the lower part (3), and is possibly even bonded thereto. The edge (8) can have a widening (10) that engages into a corresponding undercut (11) of the lower part (3). This provides a very simple and economical design for the magnetic stirrer (1), but one which is nevertheless also tightly sealed and impervious to aggressive vapors.
