Shipping container
The present invention relates to a shipping container for cryopreserved biological samples in which a cryopreserved sample can be maintained on arrival at its destination for a period of time, for example several months.
1. A container for holding at least one cryopreserved biological sample therein comprising:
a container wall comprising an outer insulating layer;
a cavity within the container for at least one cryopreserved biological sample; and
at least one thermal mass;
a heat exchanger operably connected to the at least one thermal mass and disposed entirely within the cavity; and
an infrared shield positioned within the cavity and at least partially around the heat exchanger, the infrared shield being separate from the container wall,
wherein the thermal mass and the heat exchanger are configured to recirculate air within the cavity to provide continuous cooling to the at least one cryopreserved biological sample.
2. The container of claim 1 , wherein the container comprises a pair of container halves adapted to engage together surrounding the outer insulating layer.
3. The container of claim 2 , wherein the each container half of the pair of container halves comprises an outer surface formed of a portion of the outer insulating layer, and an inner surface coupled to the outer surface.
4. The container of claim 3 , wherein the inner surface is coupled to the outer surface to allow the outer insulating layer to freely expand and contract.
5. The container of claim 2 , wherein the pair of container halves engage together using a releasable engagement means.
6. The container of claim 5 , wherein the releasable engagement means is a magnetic engagement means.
7. The container of claim 5 , wherein the releasable engagement means comprises a plurality of magnets along edges of the outer insulating layer.
8. The container of claim 1 , wherein the container further comprises one or more aperture, and one or more a sensor coupleable to the container via the one or more aperture.
9. The container of claim 8 , wherein the one or more sensor is a temperature sensor.
10. The container of claim 8 , wherein the one or more sensor is for detecting a temperature within the cavity, a temperature of a sample located in the cavity, the location of the container, the power required to maintain the temperature within the cavity stable, the amount of cryogenic phase transition material in a cartridge located in the cavity, or the volume of a cryogen within the cavity.
11. The container of claim 1 , further comprising a docking mechanism for docking the container into a shipping container having a compatible docking mechanism.
12. The container of claim 11 , wherein the docking mechanism comprises at least one magnet.
13. The container of claim 1 , further comprising a loading means for loading the at least one cryopreserved biological sample into the container.
14. The container of claim 13 , wherein the loading means is a plate shaped to be slotted into the container, and shaped to receive the at least one cryopreserved biological sample thereon.
15. The container of claim 14 , wherein the plate is shaped to receive the at least one cryopreserved biological sample thereon within one or more sample container.
16. The container of claim 15 , wherein the one or more sample container is selected from a cryopreservation bag, a vial, a multi-well plate, or tubes.
17. The container of claim 13 , wherein more than one sample container is loadable into a single container.
18. The container of claim 13 , wherein the plate further comprises a handle on one side thereof for handling the plate, both when the plate is inserted into the cavity of the container and when the plate is removed from the container.
19. The container of claim 1 , wherein the outer insulating layer comprises a polymer foam.
20. The container of claim 1 , wherein the at least one thermal mass comprises aluminum.
