Abstract

A system and method for freeze-drying a heat-sensitive substance. In some embodiments, the system and method include freeze-drying the heat-sensitive substance in an upright container with a membrane for transmitting air or vapor solvent out of the container.

Claims (22)

1. A system comprising:

an upright container comprising a body defined by an upper portion, with an opening formed therein, and a lower portion;

a removable cap sealably attached to the upper portion of the body and configured to cover the opening; and

a permeable membrane configured to transmit air or solvent vapor out of the upright container while resisting liquid or contaminant passage into the upright container, the membrane disposed above a fill line of the upright container.

2. The system of claim 1 , further comprising a membrane frame coupled to the perimeter of the membrane.

3. The system of claim 2 , wherein the membrane frame attaches to the upper portion of the body such that the membrane covers the opening of the upright container.

4. The system of claim 3 , wherein the membrane frame attaches to the top of the body via a lip and groove mechanism or threads.

5. The system of claim 2 , wherein the membrane frame is inserted into and attached to the upper portion of the body and transmits air or solvent vapor out of the upright container while resisting liquid or contaminant passage into the upright container when the cap is removed from the upper body.

6. The system of claim 5 , wherein the membrane frame is inserted into and attached to the upper portion of the body via friction fit, a lip and groove mechanism, or threads.

7. The system of claim 2 , wherein the membrane frame is inserted into and attached to the cap of the upright container and transmits air or solvent vapor out of the upright container while resisting liquid or contaminant passage into the upright container when the cap is attached to the upper body.

8. The system of claim 7 , wherein the membrane frame is inserted into and attached to the cap via friction fit, a lip and groove mechanism, or threads.

9. The system of claim 1 , wherein the upright container is a glass lyophilization vial.

10. The system of claim 1 , wherein the upright container is a conical centrifuge tube.

11. The system of claim 1 , wherein the upright container is a microcentrifuge tube.

12. The system of claim 1 , wherein the cap is a snap cap closure.

13. The system of claim 1 , wherein the cap is a plug or stopper.

14. The system of claim 1 , further comprising a heat-sensitive substance.

15. The system of claim 14 , wherein the heat-sensitive substance is a biological material.

16. The system of claim 14 , wherein the heat-sensitive substance is a pharmaceutical formulation.

17. The system of claim 14 , wherein the heat-sensitive substance is a therapeutic product.

18. The system of claim 1 , wherein the upright container is a blood collection tube.

19. The system of claim 1 , wherein the cap is a screw cap.
