1. An apparatus for separating magnetic particles, comprising:
- one or more magnets affixed to a supporting member;
a motorized mechanism configured to move the supporting member in such a manner that the one or more magnets move backwards and forwards along a fixed axis, and during at least a portion of the motion, the one or more magnets maintain close proximity to one or more receptacles which contain the magnetic particles; and
control circuitry to control the motorized mechanism.

Abstract
An apparatus for providing thermal and magnetic energy to a receptacle containing a reaction mixture and a magnetic retention member. The apparatus can also control heating of a reaction mixture, and bring about a separation of magnetic particles from the reaction mixture. The reaction mixture typically comprises polynucleotides from a biological sample that are being brought into a PCR-ready form.
