This invention relates to methods and devices that improve the process of culturing cells and/or shipping cells from one location to another. They have the capacity to reduce the risk of contamination, regulate pressure in the medium surrounding cells, and maintain cells in a uniform distribution throughout transit. This leads to an improved level of process control relative to current methods.

1. A cell container comprised of: a cell compartment, said cell compartment bounded at least in part by a sidewall and a bottom, andan access port, andan overflow reservoir and a fluid exit path connecting said cell compartment to said overflow reservoir, anda fluid displacement member capable of terminating fluid flow to said overflow reservoir, andmeans for adjusting the position of said fluid displacement member relative to the said cell compartment so that in use the fluid displacement member moves into said cell compartment when the fluid residing in said cell compartment decreases in volume. 2. A cell container comprised of: a cell compartment occupying a volume of space and bounded in part by a sidewall and a bottom, andat least a portion of said bottom being comprised of gas permeable material and said gas permeable material being flat during use, andan access port, anda cell compartment volume adjustment feature, andduring use said volume adjustment feature is able to change its position when the temperature of medium is decreased and thereby exerting a force on the fluid within the cell compartment that is great enough to keep said gas permeable material flat during a decrease in media temperature. 3. A container comprising: a cap, a cell compartment that occupies a volume of space, and a cell compartment volume adjustment feature; andsaid cell compartment adjustment feature incapable of allowing media to pass through it during use and including means for altering the volume of said cell compartment and to place said cell compartment adjustment feature into an initial state of potential energy that decreases as the cell compartment volume decreases. 4. The device of claim 1 wherein said cell compartment is comprised of gas permeable material. 5. The device of claim 1 wherein said gas permeable material is comprised of silicone. 6. The device of claim 1 wherein said fluid displacement member has a shape that includes a tapered wall that directs fluid towards the perimeter of said cell compartment. 7. The device of claim 6 wherein said fluid displacement member is in the shape of a cone. 8. The device of claim 1 wherein said fluid displacement member is hollow. 9. The device of claim 1 wherein said cell culture compartment is capable of holding media such that the highest location of the media is at a height that exceeds 2.0 cm from the lowest location of the media. 10. The device of claim 2 including a lower wall support in contact with at least a portion of said gas permeable material. 11. The device of claim 2 wherein said gas permeable material is comprised of silicone. 12. The device of claim 2 wherein said volume adjustment feature has a shape that includes a tapered wall that directs fluid towards the perimeter of said cell compartment. 13. The device of claim 2 wherein said volume adjustment feature member is hollow. 14. The device of claim 6 wherein said cell culture compartment is capable of holding media such that the highest location of the media is at a height that exceeds 2.0 cm from the lowest location of the media. 15. The device of claim 3 wherein said cell compartment is comprised of gas permeable material. 16. The device of claim 3 including a support is in contact with at least a portion of said gas permeable material. 17. The device of claim 15 wherein the gas permeable material is comprised of silicone. 18. The device of claim 3 wherein said cell compartment volume adjustment feature has a shape that includes a tapered wall that directs fluid towards the perimeter of said cell compartment. 19. The device of claim 3 wherein said cell compartment volume adjustment feature is hollow. 20. The device of claim 3 wherein said cell culture compartment is capable of holding media such that the highest location of the media is at a height that exceeds 2.0 cm from the lowest location of the media.
