ABSTRACT:
A magnetic field separation system includes a magnet unit having first and second pole members forming a linear gap with a relatively high magnetic field density therebetween. A flow chamber comprised of first and second optically transparent slides mounted so as to define a generally planar fluid pathway therebetween, passes a biological fluid over the linear gap at an angle, with flow through the pathway being accomplished by gravity and capillary action. Biological fluid, when sensitized to magnetic reaction, passes through the fluid pathway, thereby resulting in perceivable separation of the sensitized particles.
