Abstract
A system and method are provided for separating previously-collected whole blood into a red blood cell fraction and a plasma fraction by which the container of previously-collected whole blood is determined to be empty based on using the combination of the measured gross weight of the container and a calculated fluid flow rate from the container, based on weigh scale feedback. Upon detection of the empty container, flow from the container is stopped.
