AFernbach flask is a type offlask suited for large volumecell culture where the culture requires a large surface area to volume ratio. Typically, they are baffled on the bottom in order to maximizeoxygen transfer to the culture medium when shaken. The flask was named after French biologistAuguste Fernbach (1860-1939).[1] A common volume of Fernbach flasks is 2.8 L, although only less than half would typically be used to allow for the best liquid-to-air surface area for appropriate gas exchange. Fernbach flasks are about 8" in diameter, and 9" high.[2]
