A device (10) is provided for maintaining a volume of gas dissolved in a fluid (18) at a predetermined partial pressure. The device includes a first sealable, gas-tight pouch (12) containing the fluid and a second sealable, gas- tight pouch (14) encasing the first pouch and providing a space (16) between the first and second pouches. The space may be charged with an atmosphere containing a volume of the gas dissolved in the fluid that is greater than the volume of dissolved gas, at a partial pressure that is substantially the same as the partial pressure of the dissolved gas. A method is also provided for using the device to maintain a volume of a gas dissolved in a fluid at a predetermined partial pressure.
L'invention concerne un dispositif (10) pour assurer le maintien d'un volume de gaz dissous dans un fluide (18) à une pression partielle prédéterminée. Le dispositif comprend une première enveloppe scellable étanche aux gaz (12), qui contient le fluide, et une second enveloppe scellable étanche aux gaz (14), qui enveloppe la première, avec un espace (16) entre les deux. Cet espace peut être chargé d'une atmosphère renfermant un gaz dissous dans le fluide dont le volume est supérieur au volume de gaz dissous, à une pression partielle sensiblement égale à la pression partielle du gaz dissous. On décrit un procédé d'utilisation du dispositif pour le maintien d'un volume de gaz dissous dans un fluide à une pression partielle prédéterminée.
