Abstract
A roller bottle is disclosed having a plurality of sections which may be bonded after their interior surfaces have been treated to enhance cell adhesion. The bottle may be plastic so that it is disposable, and has a pair of serrated circumferential edges to improve traction when in contact with rollers on a standard cell production roller apparatus. It includes a bottom cap, a cylindrical section, a top cap having a threaded neck, and a screw cap. The bottom and top caps include the serrated edges which enable the bottle to roll rather than slip on a roller apparatus. A method for the use of the bottles is also disclosed wherein a roller apparatus is able to rotate a large number of stacked bottles.
