Claims
- 1. A method comprising:placing a vessel containing a solution including magnetized substances and non-magnetized substances into a magnetic device, the magnetic device comprising first and second north polar magnets, first and second south polar magnets, and first, second, third and fourth interpolar magnets, wherein the first north polar magnet is adjacent to the first interpolar magnet, which is adjacent to the first south polar magnet, which is adjacent to the second interpolar magnet, which is adjacent to the second north polar magnet, which is adjacent to the third interpolar magnet, which is adjacent to the second south polar magnet, which is adjacent to the fourth interpolar magnet; incubating the solution in the magnetic device for a period of time sufficient to allow the magnetized substances to migrate radially toward the interior wall of the vessel; and removing a sample of the solution from the center of the vessel, wherein the removed solution contains non-magnetized substances.
- 2. The method of claim 1, further comprising placing a magnet at a center of the vessel.
- 3. The method of claim 2, wherein the magnet is rod-shaped.
- 4. The method of claim 1, wherein, when the vessel is placed in the magnetic device, a length of the magnetic device extends for substantially a length of the vessel within the magnetic device.
- 5. The method of claim 1, wherein a cross section of the vessel is substantially concentric with a cross section of the magnetic device.
- 6. The method of claim 1, wherein the solution includes biological substances.
- 7. The method of claim 1, wherein the removed solution includes biological substances.
- 8. The method of claim 1, wherein the solution comprises a liquid having the magnetized and non-magnetized substances suspended therein.
- 9. The method of claim 1, wherein the magnetized substances comprise particles tagged with magnetic particles.
- 10. The method of claim 1, wherein the vessel comprises one of a test tube, a bottle, a beaker, and a tube.
- 11. A method comprising:placing a solution including magnetized substances and non-magnetized substances within an interior of a generally cylindrical magnetic device, the cylindrical magnetic device comprising a first north polar magnet and a second north polar magnet, a first south polar magnet and a second south polar magnet, a first interpolar magnet disposed between the first north polar magnet and the first south polar magnet, a second interpolar magnet disposed between the first south polar magnet and the second north polar magnet, a third interpolar magnet disposed between the second north polar magnet and the second south polar magnet, and a fourth interpolar magnet disposed between the second south polar magnet and the first north polar magnet; and leaving the solution in the interior of the cylindrical magnetic device for a period of time sufficient to allow the magnetized substances to migrate outward toward the cylindrical magnetic device.
- 12. The method of claim 11, further comprising removing a sample of the solution from a center of the cylindrical magnetic device, wherein the removed solution contains non-magnetized substances.
- 13. The method of claim 12, wherein the removed solution includes biological substances.
- 14. The method of claim 11, further comprising placing a magnet at a center of the cylindrical magnetic device.
- 15. The method of claim 14, wherein the magnet is rod-shaped.
- 16. The method of claim 11, wherein the solution includes biological substances.
- 17. The method of claim 11, wherein the solution comprises a liquid having the magnetized and non-magnetized substances suspended therein.
- 18. The method of claim 11, wherein the magnetized substances comprise particles tagged with magnetic particles.
- 19. The method of claim 11, wherein the solution is disposed in a container and the container is positioned in the interior of the cylindrical magnetic device.
