Abstract
A magnetic biological particle separation device comprising positioning a magnetic arrangement comprising a first magnet to generate a first north-south magnetic field in a plane co-planer with a horizontal cross-sectional plane of a container, positioning a second magnet in the magnetic arrangement to generate a second north-south magnetic field substantially opposing the first north-south magnetic field in a plane co-planer with the horizontal cross-sectional plane of the container, positioning a third magnet in the magnetic arrangement to generate a third north-south magnetic field substantially perpendicular to the first and the second north-south magnetic fields, directed radially away from the container, in a plane co-planer with the horizontal cross-sectional plane of the container, and pouring from the container a fluid containing magnetic beads, without a substantial loss of the magnetic beads.
