Patent ID: 8518272

Claim:
A system for separating components of a composition according to density comprising: a torque generating device; a separation device for separating the composition into different components according to density, the separation device including: a first end and a second end opposite to the first end, wherein a longitudinal axis extends between the first end and the second end; a sidewall extending between the first end and the second end, the sidewall defining a separation chamber; a separator within the separation chamber along the longitudinal axis; an inlet port and an outlet port each extending through the sidewall between the first end and the second end; and a counterbalance between the second end and the inlet port; and a housing that accommodates the separation device to maintain the separation device in a sterile condition when seated therein; wherein the torque generating device is external to the housing and is configured to supply torque to the separation device when seated in the housing.
