Claim:
1. A system for extraction of nucleic acids comprising an integrated separator and heater and a rack removably received in the system, the system comprising: a heater assembly, wherein the heater assembly comprises a plurality of independently controllable heater units aligned collinearly along a horizontal first axis, each of which is configured to accept and to heat a single process tube of a plurality of process tubes placed in the heater assembly; one or more magnets affixed to a supporting member, wherein all of the one or more magnets in the system are disposed on a front side of the plurality of independently controllable heater units and aligned along a second axis parallel to the first axis; a rack removably received in the system, at least a portion of the rack removably received on a back side of the plurality of independently controllable heater units opposite the one or more magnets on the front side; a plurality of holders, each holder comprising a single process tube of the plurality of process tubes, the plurality of holders removably received in the rack such that a portion of each process tube is received in a single heater unit of the plurality of independently controllable heater units as the rack is inserted into the system; a motorized mechanism configured to move the supporting member in such a manner that all of the one or more magnets move uniformly backwards and forwards together in a vertical direction perpendicular to the second axis, and during at least a portion of the motion all of the one or more magnets simultaneously maintain proximity to an exterior side of each of the process tubes in the heater assembly sufficient to move magnetic particles contained in the process tubes against a wall of the process tubes; and control circuitry to control the motorized mechanism and to control heating of the heater units.
