Abstract:
1. A system for separating fluids by centrifuging, the system comprising: a rotor assembly for rotating in a centrifugation device, said rotor assembly including: (a) a first rotor for housing at least one container, each said container containing a sample for separation by centrifuging; (b) a second rotor having at least one collection compartment, each compartment corresponding to a particular container of said at least one container, and (c) at least one conduit, each conduit corresponding to a particular compartment of said at least one compartment, each conduit for providing fluid communication, upon demand, between said particular container and said particular compartment, so as to enable transfer of a separated fraction of each said sample from said container into said compartment, wherein said collection compartment is designed for fluid communication with an ambient environment, so as to operate at a substantially ambient pressure during the centrifuging and during a filling of said collection compartment with said separated fraction.
