Abstract:
1. A system having a fluid flow path for processing biological material comprising red blood cells and nucleated cells, comprising: A vessel for containing and enabling the biological material to separate into two or more distinct layers of submaterials, wherein one of the distinct layers of submaterials comprises a layer of red blood cells; An extraction device configured to remove the layer of red blood cells from the vessel, wherein the extraction device comprises a pick up line having a distal end located within the vessel at a level at which the layer of red blood cells settles during operation; A filtration device, located downstream along the fluid flow path from the extraction device, for separating the nucleated cells from the remaining submaterials; A valve located between the vessel and the filtration device; A conduit through which one or more submaterials are transported between the vessel and the filtration device; and A control device configured to automatically initiate the extraction device to remove the layer of red blood cells from the vessel and after removal of the red blood cells, to automatically open the valve to transport one or more of the submaterials remaining in the vessel further downstream along the fluid flow path to the filtration device via the conduit.
