Due to its flat shape, the culture flask is stored lying according to Roux and thus permits a relatively large growth surface. With this design, the neck is eccentrically positioned and thus prevents the liquid culture medium from leaking out.– With this design, the neck is eccentrically positioned and thus prevents the liquid culture medium from leaking – Due to the flat, large floor surface, the layer cover of microorganisms can grow evenly high – The large liquid surface ensures better aeration and thus faster growth of the microorganisms – – Due to its flat shape, the culture flask is stored lying according to Roux and thus permits a relatively large growth surface.
