Abstract: The mixing or dispersing device and assembly equipped with such a device are proposed for optimizing the processing of mixed or dispersed substances, in particular tablets and/or capsules for medicinal drugs. The mixing or dispersing device includes in a mixing chamber, a motor-driven rotor having at least one cutting projection that has at least one cutting edge. A flow-disturbing element is further provided on an inner circumferential wall of the mixing chamber that surrounds the axis of rotation. Furthermore, a deflection surface is provided between the inner circumferential wall and a bottom of the mixing chamber. The at least one flow-disturbing element is spaced from the bottom of the mixing chamber, from the at least one cutting projection and from the circular path on which the at least one cutting projection is movable about the axis of rotation.

Abstract: The aim of the invention is to reduce the overall height of a magnetic coupling (1) which is particularly suitable for use in a magnetic stirrer. For this purpose, at least one magnet (4) of the rotor (3), which magnet is designed as a driving magnet for a counter-coupling piece of the magnetic coupling, particularly for a stirring magnet of a magnetic stirrer, and is arranged such that it projects at least partially or completely into a space (7) encompassed by a rotor-stator unit (5) of the magnetic coupling (1) and/or projects at least partially or completely into said space (7).

Abstract: A microtiter plate (1), which can be used in a device G, comprises a plurality of receptacles (2) disposed next to one another for a substance or fluid to be stirred and analyzed, wherein stirring rods (3) are provided for stirring. So as to drive these stirring rods, it is provided that the bottoms (4) of the individual receptacles (2) are displaceable and deflectable and that a stirring rod (3) penetrates each of them centrally, the rod being seized by a drive on an outer section (3b) protruding downward beyond the bottom (4) such that it can be set into a back and forth motion or a gyrating or rotary motion and thus continues the desired stirring motion on the inside of the receptacle (2).

Abstract: A stirring or dispersing device (1), has a hermetically sealed mixing chamber (5), a tool (2), and a drive mechanism (4) located outside of the mixing chamber (5). The tool (2) can be driven around a central shaft in the mixing chamber (5) which has a rod-shaped element (3) for force transmission from the drive mechanism (4) to the tool (2). The rod-shaped element (3) is connected at the entry to the mixing chamber (5) with a diaphragm (6), which is a part of the wall (7) of the mixing chamber (5), and the rod-shaped element (3) can be put into a wobbling movement by the drive mechanism (4), so that its end located in the interior of the mixing chamber (5) performs a rotating movement. The tool is constituted by a number of grinding elements (22) or balls to be introduced into the mixing chamber (5).

Abstract: An agitating or dispersing apparatus (1) with a hermetically sealed mixing chamber (5), an agitating or dispersing tool (2) that can be driven in this mixing chamber (5) about a central axis and with a rod-shaped element (3) for transferring the power of a drive (4) onto this tool (2), and with the drive (4) located outside of the mixing chamber (5). The rod-shaped element (3) is connected at the entrance into the mixing chamber (5) to a membrane (6) that is part of a wall (7) of the mixing chamber (5), and the rod-shaped element (3) can be put in a wobbling motion by the drive (4) so that its end inside the mixing chamber (5) executes a circular motion. The end of the rod-shaped element (3) located in the mixing chamber (5) attacks the tool (2) eccentrically to its axis of rotation.

Abstract: A dispersing tool (1) is provided having a hollow shaft (2), which has an open, laterally slotted region on its free end (4) that faces away from a drive that is at the bottom in the position of use, and with an inner shaft (3), which can rotate in this hollow shaft (2) and which has a dispersing tool (5) interacting with this hollow shaft in the region of the slotted end of the hollow shaft (2). Upon rotation, the inner shaft creates a pumping effect directed towards the free end (4). To counteract the pumping effect of a smooth inner shaft in a direction towards the drive and simultaneously to prevent eccentricities in the profile of the inner shaft (3) and to guarantee simple manufacturing, the inner shaft (3) has at least one section (6) with an increasing cross section and the cross section increases from the drive side toward the free end (4).
