Transfertset comprising a bottle, a cartridge and a device for two-way transfer of a liquid between the bottle and the cartridge

摘要

The liquid transfer apparatus consists of a housing with a connector (30) for fitting it to a flask, a tube holder (80) and a mobile component (20), and a spacer (22) acting as a stop for a moving perforable piston inside the tube. The apparatus incorporates a hollow needle (24) that is fixed axially relative to the housing, while the spacer can be moved between a first position in which the piston is held at a distance from the needle, and a second position in which the needle passes through the piston.
