ABSTRACT:
The invention is a device for sampling and/or injecting a fluid which evolves according to a reversible reaction, that enables the fluid to be restored to its initial state. The device inside a fluid sampling enclosure produces a counterpressure value necessary for restoring the fluid to its initial state without causing a change in its composition.
