Abstract:
1. A method for collecting and washing magnetic particles in a vessel, comprising: a) providing a vessel with magnetic particles suspended in a first fluid, said vessel comprising a planar area particle engagement side; b) introducing the vessel into a vessel holder comprising, i) a holder lumen, ii) a vertical surface, comprising a magnet, and iii) a lever arm, wherein a lever arm is mounted to a pivot point proximal to a lower end of said lever arm; reciprocally moving said lever arm from a vertical position to a lever arm tilted position relative to the vertical surface of the holder when said vessel is received in the holder lumen between the vertical surface and said lever arm, biasing said lever arm toward said vertical position; c) collecting the magnetic particles in said vessel at a bottom portion of said planar area particle engagement side of said vessel by magnetic attraction to said magnet; and d) washing said magnetic particles.
