Abstract
A cell culture flask includes a hollow housing and a gas permeable membrane disposed within the housing which divides the housing into a first chamber and a second chamber. A retaining ring secures the gas permeable membrane within the housing and forms a liquid-tight seal between the first chamber and the second chamber. A gas inlet in the housing communicates with the first chamber and supplies gas thereto. A media inlet in the housing communicates with the second chamber and provides cell growth media thereto.
