Abstract
The aim of the present invention is to provide a solution to the problem of mixing in a vessel two or more substances of which at least one is a liquid phase. The vessel preferably comprises a container having an open upper end which may be advantageously surrounded by a rim, and a closed bottom end. The mixing device most preferably comprises a support plate adapted to receive the container and to allow engagement therewith by a rotating mixing cylinder. A single rotational movement e.g. from a drive motor acting through a drive cylinder, causes the rotating mixing cylinder to simultaneously engage the sample container and drive the bottom of the container in a circular motion around a vertical axis in order to generate a vortex in the substances to be mixed. Very effective, automated mixing of the substances is thereby effected.
