A magnetic device that separates red blood cells from the whole blood on a
continuous basis is presented. The device utilizes permanent magnets in alt
ernating spatial arrangements. Red blood cells are coupled with magnetic mi
crospheres to facilitate the magnetic separation. Effectiveness of red bloo
d cells separation and purity of plasma solution was improved using the dev
ice over conventional centrifugal methods. (C) 1999 Elsevier Science B.V. A
