Abstract
A process for filing a syringe in which a longitudinal tubular syringe barrel has a first end closed by a movable plunger and a connection suitable for an injection needle at its second end, this second end of the bore being closed by a penetrable closure, and the syringe is filled by passing a filling needle through the penetrable closure and filing the barrel with a liquid via the needle, then withdrawing the filing needle from the closure. Suitably a penetrator is attached to the second end of the barrel to penetrate and provide communication through the closure.
