A device (1) for the treatment of a liquid material (2) under a controlled atmosphere. The device makes use of a) first receptacle (3), for containing the liquid material (2); b) a confinement enclosure (4) connected to a system (5) for controlling the pressure of an essentially gaseous fluid inside the enclosure (40; c) a second receptacle for receiving and containing the liquid material (2) having been subjected to a purification treatment by passing it through the confinement enclosure (4); d) a transfer system (7), for taking the liquid material (2) in the first receptacle (3) then making it come forward in the confinement enclosure (4) against an exposure surface (8) in the form of a layer of which the free face (9A) is exposed in the enclosure (4) and evacuating it towards the second receptacle.
