Centrifugation Of Blood Blood banks are global wide industries that are involved in the separation of mixtures obtained from living matter. They take blood donation from humans and separate the white/red bloods cells platelets and plasma from each other for various beneficial uses, for example plasma or platelet transfusion. Centrifuging is used to hasten the separation of blood. Centrifugation is a separation process which uses the action of centrifugal force to promote accelerated settling of particles in a solid-liquid mixture. There are different types of centrifugal separation. There is the Differential centrifugation and Density gradient centrifugation. The Density gradient centrifugation and be classified into two categories, Rate zonal and Isopycnic separation. Density gradient centrifugation is the preferred method to purify subcellular organelles and macromolecules. Density gradients can be generated by placing layer after layer of gradient media such as blood in a tube with the heaviest layer at the bottom and the lightest at the top in either a discontinuous or continuous mode. The cell fraction to be separated is placed on top of the layer and centrifuged. Density gradient separation can be classified into two categories. Size separation and density separation. This method of centrifugation is most commonly used in the separation of blood components. The properties used in the separation of blood are the density of the blood components. The can be separated into different sections because some particles from whole blood cells are far more dense then others, for example red blood cells and plasma. Red blood cells are more dense then plasma cells. The products that come out from the separation of blood cells are plasma, packed red blood cells, white blood cells and platelets. They are all very useful to those who lack these blood
