blood cell separator
Red blood cells make up slightly lower blood volume than blood plasma — about 45% of whole blood. As you probably already know, these types of blood cells contain hemoglobin, which in turn consists of iron that helps transport oxygen throughout the body. The permeability of red blood cells is slightly less than 1 (1 – 3.9e-6). Or to put it in words, red blood cell particles are diamagnetic.
