A method and apparatus for plasma modifying a workpiece such as a medical barrel, medical barrel, vial, or blood tube is described. Plasma is provided within the lumen of the workpiece. The plasma is provided under conditions effective for plasma modification of a surface of the workpiece. A magnetic field is provided in at least a portion of the lumen. The magnetic field has an orientation and field strength effective to improve the uniformity of plasma modification of the generally cylindrical interior surface 16 of the generally cylindrical interior surface 16. A vessel made according to the process or using the apparatus described above. A pharmaceutical package comprising the medical barrel or vial containing a pharmaceutical preparation, secured with a closure. L'invention concerne un procédé et un appareil pour un plasma modifiant une pièce, telle qu'un tube médical, un flacon ou un tube de sang. Un plasma est disposé à l'intérieur de la lumière de la pièce. Le plasma est fourni dans des conditions efficaces pour une modification de plasma d'une surface de la pièce. Un champ magnétique est créé dans au moins une partie de la lumière. Le champ magnétique a une orientation et une force de champ efficaces pour améliorer l'uniformité de modification de plasma de la surface intérieure généralement cylindrique 16 de la surface intérieure généralement cylindrique 16. L'invention concerne un récipient fait selon le procédé ou par utilisation de l'appareil décrits ci-dessus. L'invention concerne également un emballage pharmaceutique comprenant le tube ou flacon médical contenant une préparation pharmaceutique, fermé à l'aide d'une fermeture.
