摘要

PROBLEM TO BE SOLVED: To provide a measuring implement which comprises a centering element having an axial air passage inside a syringe cylinder holder and a piston holder axially displaceable for a syringe piston; and a syringe for using with the same.

SOLUTION: The syringe includes: a syringe piston; a syringe cylinder having an opening in the bottom; a centering flange disposed at the top on the outer circumference for insersion into the holder; a cylindrical piston movement area which is connected to the exit having a first inner diameter to guide the syringe piston hermetically; and a centering area which has a second inner diameter beyond the first inner diameter at least 3 mm apart from at least the top of the syringe cylinder in order to insert an at least 16.2 mm long centering element, wherein the syringe piston at the top has a connection piece for insersion into the piston holder.
