Abstract
The Specification discloses a parallel-piped freezing frame having a plurality of compartments for freezing of flexible bags of plasma or other biological fluid. A slidable freezing plate is mounted within each compartment and cam means are provided for directing the freezing plate downwardly and laterally against a side wall of the component. The freezing plate and associated planar wall thereby mold the flexible bag into a flat but slightly wedge-shaped configuration. A freezing medium such as alcohol circulates through the freezing frame to freeze the contents of the flexible bag.
