  • Magnetic separation device
    Patent number: 4710472
    Abstract: A magnetic separation device suitable for removing magnetic bead-coated cells from a system comprising a base, a plurality of magnets mounted on the base such that a sample chamber is created for holding sample containers which are to be placed in close proximity to the magnets, and a means for adjusting the position of the magnets with respect to the sample container. A blood sample containing magnetic bead-coated cells is passed through tubing which is mounted in close proximity to the magnets. The magnetic bead-coated cells are attracted by the magnets and retained in the tubing while the nonmagnetic cells pass through the tubing.
