<p>A tube mixing device and a bottle rolling device each for use with a magnetic stirring (10) device having a propelling magnet (12) mounted on the motor shaft of an electric motor. The devices both comprise a base element (20) and an outer element (42). The outer element of the tube mixing device is disposed at an angle relative to the base element and is adapted to hold tubes. The outer element (114) of the bottle rolling device comprises a plurality of rollers rotatably mounted in side by side arrangement. Both outer elements have a propelled magnetic field means associated therewith and are provided with drive means through which the respective outer elements may be driven by the propelled magnetic field means, the arrangement being such that movement of the outer elements is effected by magnetic coupling of the propelled magnetic field means to a propelling magnetic field means of a magnetic stirring device. <IMAGE></p> |
