ABSTRACT:
A sparger for use in microcarrier fermentation systems is provided which includes a narrow, vertically extending outer chamber defined by a solid wall and a wall formed by a screen, wherein air or other gas is forced under pressure through a tube to the bottom of the chamber and from there to a distribution member for the release of the gas upwardly into the chamber. The top of the chamber is provided with exit openings which communicate to a point above the surface of the medium. In an alternate embodiment, gas is released at the bottom of an inner chamber defined by a wall formed with a plurality of screened windows.
