Method and apparatus for magnetic separation of particles

摘要

A method and apparatus for magnetic separation of particles within a container. In one embodiment, a plurality of magnets are arranged in a first row and in a second row on a frame, wherein the plurality of magnets are oriented in a plane coplanar with a horizontal cross sectional plane of the frame. The frame has housing means between the first row and the second row for housing containers. The plurality of magnets apply north-south magnetic fields oriented coplanar with the horizontal cross sectional plane of the frame. The north-south magnetic field direction of a first magnet in the first row alternates 180 degrees from the north-south magnetic field direction of a second magnet in the first row, and the north-south magnetic field direction of a first magnet in the second row opposes the north-south magnetic field direction of the first magnet in the first row.
