Device for interfacing a vial to be perforated

An interfacing device intended to establish a connection between a fluid-injection instrument and a vial to be perforated, comprising:

• a base comprising:
• a first conduit, suitable for being attached to the vial to be perforated,
• a second conduit suitable for allowing circulation of gases in the vial to be perforated, and
• a third conduit suitable for being connected to the fluid-injection instrument,
• means for circulating the fluids, comprising a proximal orifice in fluidic communication with the third conduit, wherein said means for circulating the fluids further comprise a tube, housed in the second conduit and translationally movable in said second conduit, said tube comprising at its distal end a distal orifice in fluidic communication with the second conduit, the proximal orifice and the distal orifice being configured for opening into the vial to be perforated when the interfacing device is attached to said vial to be perforated,
• said interfacing device further comprising a gas exchange device including at least one of a filter or a tank attached to a proximal end of the tube, wherein said gas exchange device is in fluid communication with the tube in order to allow circulation of the gases from the vial to be perforated.
