Abstract
A flexible container receives a liquid material, which is freeze-dried in situ within the flexible container. A gas permeable material that is separate from the flexible container provides gas transport for sublimation during drying and lyophilization. The gas permeable portion of the system can be isolated and removed from the flexible container post-lyophilzation The freeze-dried material is stored in the flexible container until administration is necessary. The flexible container receives a reconstituting liquid for mixing with the freeze-dried material, and conveys the reconstituted freeze-dried material from the flexible container for administration to an individual.
