Abstract
A method, system, and vacuum head assembly provide hermetic sealing of fluid medicament cartridges through vacuum stoppering with the assistance of accurate and repeatable mechanical positioning and handling of the stopper. Inert gasses may be introduced during the stoppering process so as to provide headspace or in the alternative completely eliminate headspace. The stopper may be provided with longingutidly spaced apart sealing and control rings providing an opportunity to introduce a stabilizing gas between the rings and a side wall of the cartridge to be hermetically sealed.
