Abstract
A freeze-dried material is stored in a first chamber of a container along with a reconstituting liquid for the freeze-dried material, which is stored in a second chamber of the container. A sealing wall within the container forms a barrier between the first chamber and the second chamber preventing contact between the freeze-dried material and the reconstituting liquid. At least one valve assembly in the sealing wall selectively opens a region of the sealing wall to establish fluid flow communication between the first and second chambers, allowing the freeze dried material to be reconstituted. The reconstituted freeze-dried material can be administered from the same container to a recipient.
