System and method for freeze-drying and packaging
First Claim
1. A method, comprising:
- inserting a biological material into freeze-drying container in which a first container side includes a gas-permeable membrane;
freeze-drying the biological material in the freeze-drying container, including allowing air or solvent vapor to escape the container through the membrane; and
sealing the biological material within a portion of the freeze-drying container spaced from the membrane.

Abstract
A system and method for protecting biological or other material from contamination through the steps of filling, freeze-drying, packaging, storing and use are disclosed. A system can include a flexible container, a membrane configured to transmit air or solvent vapor out of the flexible container, and a membrane frame supporting the membrane and engaged with at least one column member. The at least one column member can be configured to maintain the membrane and the membrane frame a spaced distance from one or more contents received within the flexible container. Upon application of a downward force, the at least one column member can assume a collapsed configuration. A method can include inserting a biological material, for example, into a flexible container, freeze-drying the biological material, moving the freeze-dried biological material to a portion of the flexible container that includes at least one port, and sealing the biological material within the portion.
