ABSTRACT:
Blood plasma is frozen in a sealed, flexible, collapsible container which defines an inlet at one end and a shoulder portion surrounding the inlet. The container tapers from the shoulder portion to a generally flat configuration at its end opposite the one end. After the freezing step, the shoulder portion is cut away from the container to define a cut end. Thereafter, the frozen plasma may be removed from the container in frozen form by squeezing the wall of the tapered container to expel the frozen plasma out of the cut end of the container.
