Abstract
An apparatus and method are provided for separating components of a fluid or particles. A separation vessel (28) having a barrier dam (62) is provided to initially separate intermediate density component of a fluid, and a fluid chamber (30) is provided to further separate these intermediate density components by forming an elutriative field or saturated fluidized particle bed. The separation vessel is placed in a retainer on a centrifuge rotor (12) and ridges (68) in the retainer form various dams (70) in the separation vessel. Also disclosed are tubing sets and various separation vessels for use with the apparatus.
