Abstract
Apparatus for the centrifugal fractionation and component-isolation of liquid material has a nonflexing radially-movable pressure panel disposed between a first liquid container stacked radially in front of a second liquid container. The two containers are at the same interval pressure during centrifugation, and the pressure panel avoids radial distortion of the back wall of the first container. The liquid container structure can incorporate the pressure panel. Alternatively, the panel can be part of the centrifugal separating instrument.
