The Vacuum Stoppering Unit is typically used to insert and seat stoppers (Syringe Bungs) - or plunger rods - in unit dose syringes also called pre-filled syringes. But it is not limited to this application. Some other applications include: insertion of stoppers(bungs)into vials or evacuation of glass tubes sealed with stoppers(bungs)on both ends.
The Vacuum Stoppering Chamber consists of stainless steel vacuum chamber with an air-driven transfer punch plate assembly and a separate control box. The latter automatically controls the process in the chamber.
During operation the loaded syringe rack is put in the chamber; the transfer punch plate is moved by a short stroke sufficient to seal the stopper to the syringe; a vacuum is reached; and then released. The venting of the chamber restores atmospheric pressure creating a pressure differential between the top and bottom of the stopper - thus providing a final seating of the stopper in the syringe.
The chamber is constructed of materials that are fully autoclavable - allowing the chamber as a unit to be sterilized easily. A wide selection of transfer punch plate assemblies, as well as custom assemblies, makes this system versatile and adaptable to numberless applications.
