Abstract
Fluid processing assemblies and methods are provided for mononuclear cell collection. Mononuclear cells are separated from red blood cells in a blood separation chamber, with the mononuclear cells and then the red blood cells exiting the chamber via an outlet port. The mononuclear cells and then the red blood cells enter an outlet flow path that is in fluid communication with a mononuclear cell collection container. The outlet flow path includes a visual indicium, which an operator may use to determine the position of the red blood cells within the outlet flow path and when to end mononuclear cell collection by preventing fluid communication between the outlet flow path and the mononuclear cell collection container.
