Abstract
A method for transferring a viscous material into a syringe that has a plug dividing a syringe interior into a first sub-chamber and a second sub-chamber, where a radial clearance exists between the plug and the syringe, includes transferring the viscous material from a container into the first sub-chamber to fill the first sub-chamber while allowing air initially present within the first sub-chamber to flow into the second sub-chamber via the radial clearance, and flowing a first volume of the viscous material into but not through the radial clearance such that the viscosity of the first volume of the viscous material and the radial clearance cooperate to block a flow of a second volume of the viscous material into the radial clearance and prevent the second volume of the viscous material from leaking from the first sub-chamber into the second sub-chamber.
