Abstract
Apparatus and method for collecting, processing, and storing blood components, such as plasma. The method involves collecting the blood component in a flexible storage bag manufactured from ethylene vinyl acetate EVA, having a composition of between about 9% and about 18% vinyl acetate by weight of total EVA co-polymer. The EVA bag is sealed, and the sample is frozen in the bag at a temperature of at least as low as -30.degree. C. to form a substantially solid pellet contained in the storage bag. The bag then is fractured and the pellet is removed in its intact, frozen form. The co-polymer bag may have an inner surface with an etched or embossed pattern of sufficient dimensions to permit removal of the plasma in a frozen state from the storage bag.
