Abstract (en)

[origin: EP0192794A1] A vessel for preserving liquids for use in analyzers for liquid samples is formed of a closed bag member (4) consisting of membrane members (2), of which a mouth portion (1) is tightly sealed with a rubber plug (3). The membranes have a remarkably small permeability to air and water vapour and great flexibility. Via an automatic device the penetration of air, water vapour and the like into the vessel from outside can be controlled when the volume of the liquid is reduced that is to say, when the calibrating solution contained in the vessel is consumed.
