Claim 0:
1. A method of using a cell separation system to separate cells, said cell separation system comprising:
an assembly removably coupled to a containment mechanism, the assembly comprises:
a single-walled centrifugation bowl comprising a plurality of cell concentration areas, a reservoir, and a center column comprising a plurality of fluid lines,
a cradle, wherein the cradle comprises a plurality of apertures formed concentrically through the cradle, wherein the centrifugation bowl is removably coupled to the cradle to enable free rotation of the centrifugation bowl while coupled to the cradle, and
an alignment mechanism coupled to the containment mechanism and the centrifugation bowl to restrict movement of the center column of the centrifugation bowl when the assembly is coupled to the containment mechanism,
wherein the method comprises:
(a) agitating, in the reservoir of the cell separation system, a volume of biologic material and a volume digestion media to form a digested volume of biologic material;
(b) centrifuging the digested volume of biologic material in the single-walled centrifugation bowl at a force from about 500 G to about 1000 G from about 5 minutes to about 10 minutes to separate the digested volume into a plurality of concentrated cell volumes and a plurality of waste;
(c) removing a portion of the plurality of waste via at least one fluid outlet;
(d) isolating a different portion of the plurality of waste, wherein the different portion of the plurality of waste comprises waste with a larger diameter than the at least one fluid outlet and is not in contact with the concentrated cell volumes; and
(e) removing the concentrated cell volumes from the reservoir.
