An electrically-powered device intended to be used in a blood donor facility to process large volumes of blood using centrifugal force, usually to separate red blood cells or platelets from plasma for subsequent patient infusion, storage, or further processing. It is typically a large stationary structure with an electric motor, a shaft, a tachometer, and speed and time controls; it also includes a rotor for mounting one of several interchangeable heads with slots to fit sample holders (tubes/bags). It may additionally have refrigeration capabilities to perform temperature-sensitive procedures.
