1. A system for analyzing nucleic acids, comprising:
a receiving bay configured to receive a plurality of lysing tubes aligned along a lysing axis and a plurality of mixing tubes aligned along a mixing axis generally parallel to the lysing axis, the receiving bay comprising:
one or more first magnets aligned along a first magnet axis generally parallel to the lysing and the mixing axes, the one or more first magnets configured to move between a position below the plurality of lysing tubes to a position adjacent to the plurality of lysing tubes when the plurality of lysing tubes are received in the receiving bay, the one or more first magnets configured to apply a first magnetic force to contents of the plurality of lysing tubes when the plurality of lysing tubes are received in the receiving bay and the one or more first magnets are positioned adjacent to the plurality of lysing tubes, and
a plurality of second magnets enclosed within a plurality of housings aligned along a second magnet axis generally parallel to the first magnet axis, each housing of the plurality of housings enclosing two of the plurality of second magnets, the plurality of second magnets configured to remain stationary when the plurality of mixing tubes are received in the receiving bay, the plurality of second magnets configured to apply a second magnetic force to contents of the plurality of mixing tubes when the plurality of mixing tubes are received in the receiving bay.
