  • forming a plastic syringe barrel in an injection molding machine, said syringe barrel having a cylindrical wall, an open proximal receiving end and a frustoconically shaped outlet nozzle at its distal end;

    transferring said syringe barrel, without any additional cleaning or sterilization, into an environmentally controlled area to maintain a predetermined cleanliness level;

    directing a stream of filtered air toward said syringe barrel in said environmentally controlled area to loosen particulates from surfaces of said syringe barrel and applying a vacuum to remove said loosened particulates from said surfaces thereof to clean said syringe barrel;

    delivering a tip cap to said environmentally controlled area;

    assembling said tip cap to said outlet nozzle of said syringe barrel to close said outlet nozzle;

    filling said syringe barrel with a substance through its open proximal end;

    delivering a stopper to said environmentally controlled area;

    inserting said stopper into said open proximal end of said barrel to form a prefilled syringe; and
