Abstract
A roller bottle is provided with provision for increased internal surface area for cell growth by the use of a foamed, textured or woven liner or sleeve inserted into the bottle prior to use. The sleeve may be used in a single use roller bottle or a multiple use roller bottle. With the latter, the sleeve is discarded, the bottle sterilized, and a new sleeve or liner is inserted. The interstices of the foamed, textured or woven surface has the effect of increasing the actual surface area available for culturing cells in each single roller bottle, thus making the roller bottle of the invention cost effective.
