Abstract
Centrifuges are provided for rotating fluid separation chambers about an axis in a fluid processing system. The centrifuge may be provided with high- and low-G walls, with a gap defined between the high- and low-G walls. A first section of the gap may have a substantially uniform radius about the axis, while a second section of the gap may have a non-uniform radius about the axis. The radius of the second section of the gap about the axis at all locations is no larger than the radius of the first section of the gap about the axis. The high-G wall may comprise an inner surface of an outer bowl, while the low-G wall may comprise an outer surface of an inner spool. At least a portion of the second section of the gap may have a varying radius along the axis and/or be configured as a spiral.
