<p>Apparatus for fast separation of magnetic particles in suspension in a liquid contained in a reaction vessel of the type used in an automatic sampler for processing biological samples, comprising: (a) a rotatable carrier (11) holding an array of magnet elements (14-19); (b) said array of magnet elements (14-19) comprising a first magnet element (14) and at least a second magnet element (15), said magnet elements being positioned on the carrier (11) at different distances from the rotation axis (51) of the carrier and the centers of the first and second magnet elements lying on radii located at different azimuth angles, the carrier (11) and the array of magnet elements being so dimensioned that by rotation of the carrier the first magnet element (14) can be positioned close to the external side wall of the reaction vessel (13) on one side thereof and at a first predetermined height, and that by further rotation of the carrier (11), the second magnet element (15) can be positioned close to said external side wall at a second height, said second predetermined height being different from said first one; and (c) selectively positioning said carrier (11) at a plurality of predetermined angular positions. <IMAGE></p> |
