1. Apparatus for separating magnetic particles in suspension in a fluid, said apparatus comprisinga first carrier holding a plurality of first magnetic elements at different locations on said first carrier;

  • a second carrier offset from said first carrier and holding a plurality of second magnetic elements at different locations on said second carrier, said first and second carriers defining a region therebetween;

    each of at least one of said first magnetic elements being disposed across said region from a corresponding one of said second magnetic elements, at least one other one of said first magnetic elements not being disposed across said region from any magnetic element on said second carrier, and at least one another one of said second magnetic elements not being disposed across said region from any magnetic element on said first carrier;

    means for holding a reaction vessel containing said suspended magnetic particles in said region; and

    means for providing relative motion between said carriers and said holding means.
