Apparatus for separating magnetic particles

摘要

Apparatus is disclosed for separating magnetic particles in suspension in a liquid contained in a reaction vessel of the type used in an automatic apparatus for processing biological samples. The apparatus comprises a rotatable carrier holding an array of magnet elements positioned on the carrier at different distances from the rotation axis of the carrier and at different azimuth angles. The carrier and the array of magnet elements can be positioned at a plurality of predetermined angular positions and heights.
