1. Apparatus for mixing and separating magnetic particles in containers with liquid and said particles therein comprising;

  • a. a first support means for mounting one or more containers in a ring configuration;

    b. a second support means for mounting magnets in at least two concentric magnet rings spaced apart to position said container ring there between;

    c. said first support means and said second support means aligned in the apparatus to make said container ring and said two magnet rings concentric on a common axis;

    d. said two magnet rings constructed and configured to dispose a magnet of each ring alternately on opposites sides of each container;

    e. means for providing rotary motion to either said first support or said second support in the horizontal plane to alternately displace each magnet of said magnet rings at opposite sides of each container in said container ring to disperse said magnetic particles in liquid inside said containers; and

    f. means for stopping said rotary motion to position each magnet in said two magnet rings in close proximity to each container of said container ring to aggregate said particles on the inner wall of said containers.
