Abstract
A cell culture system and apparatus is provided for the agitated suspension culturing of mammalian cells in a flask assembly in which the culture medium and cells are gently agitated by the slow rotation of agitator means suspended downwardly in the culture medium and having at least one flexible sheet with a relatively large surface area which is positioned on the agitator in a manner to allow it to billow like a sail as liquid spills from its trailing edge during said rotation of the agitator means.
