An apparatus (20) and a method for capping and sealing a vial with a cap assembly including a deformable annular seal, e.g., a ferrule, is disclosed. The apparatus (20) comprises a base (24) for holding the vial, a pressure applying platen (38), plural sealing rollers (32) and associated electronic circuitry and motors. The platen (38) is arranged to be moved relative to the base (24), whereupon it engages and applies a force to the cap assembly. A load cell (34) measures the force applied and provides a signal indicative thereof to the electronic circuitry. The electronic circuitry determines when a desired amount of force has been applied to control the operation of the rollers (32), whereupon the rollers apply a force to the annular seal to permanently crimp the annular seal on the vial. |
