Abstract
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.
Claims20
A cell container comprised of:
- a cell compartment, said cell compartment bounded at least in part by a sidewall and a bottom, and
- an access port, and
- an overflow reservoir and a fluid exit path connecting said cell compartment to said overflow reservoir, and
- a fluid displacement member capable of terminating fluid flow to said overflow reservoir, and
- means 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 more elements
A cell container comprised of:
- a cell compartment occupying a volume of space and bounded in part by a sidewall and a bottom, and
- at least a portion of said bottom being comprised of gas permeable material and said gas permeable material being flat during use, and
- an access port, and
- a cell compartment volume adjustment feature, and
- during 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.
2 more elements
A container comprising:
- a cap, a cell compartment that occupies a volume of space, and a cell compartment volume adjustment feature;
- and
- said 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.
