Abstract:
A magnetic separation apparatus comprising:a plurality of magnets 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; and housing means between the first row and the second row for housing containers, wherein the plurality of magnets apply north-south magnetic fields oriented coplanar with the horizontal cross sectional plane of the frame, wherein 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.
