Abstract
A gas permeable cover for a cell culture or medium storing container which comprises a solid support sized to fit the opening of the container to be covered and has at least one hole which is covered with a permeable section. The permeable section is sufficiently permeable to oxygen and carbon dioxide that live cells can be sustained, and is substantially impermeable to water and water vapor such that the covered containers can be stored in non-humidified chambers without substantial evaporation of water. The cover further has a seal portion which forms a water-and gas-tight seal between the cover and the container when the cover is placed upon the container as configured for use.
