Abstract
A magnetic selector includes a housing configured to receive a container and having a floor upon which the container is disposed. The selector also includes a magnet carrier disposed on an opposite side of the floor from the container. The magnet carrier has at least one magnet disposed thereon and being moveable relative to the floor between a first state wherein the magnet carrier is adjacent the floor and a second state wherein the magnet carrier is spaced from the floor. The selector may include a door. The magnetic selector is usable in a fluid processing system that includes a fluid processor connectable to a source container filled with a biological fluid. A container is disposed in the magnetic selector and connected to the processor along a fluid pathway. The processor is configured to separate the biological fluid from the source container into at least two streams of material.
