Method and apparatus for syringe barrel closure removal and measurement of breakaway and running forces of a plunger in a syringe barrel

摘要

Method and apparatus for removing an elastomeric closure from the tapered tip of a pre-filled syringe or cartridge barrel stoppered at its open end by a slidable plunger; measuring the removal force required to remove the elastomeric closure from the tapered tip of the barrel; and subsequently measuring the breakaway and running forces required to move the plunger from its initial position toward the distal end of the syringe or cartridge barrel.
