<p>An apparatus for selectively holding and releasing an object in an analysis system is set forth. The apparatus comprises first and second arm assemblies that are mounted for rotation about a corresponding pair of axes. Each arm assembly includes an object holding end and a magnetic end disposed opposite one another about the respective axis. A magnetic drive is provided to magnetically induce rotation of the magnetic ends of the first and second arm assemblies about their respective axes between an open state in which the holding ends are distal one another to allow placement of the object that is to be held therebetween and a closed state in which the holding ends are driven proximate the object. The apparatus may be readily adapted to receive and hold a variety of objects, such as test tubes, vials, microscope slides, etc.</p> |
