1. A closed container for holding calibrating fluids with a specified pH or partial pressure of gas as a reference in liquid analysis device for measuring parameters of a sample of fluid, comprising:

  • an elastic, impermeable thick-wall or barrier type of bag enclosure for containing gases within an aqueous solution, said container having a fluid flow outlet connecting element;

    wherein said connecting element is a self-tightening elastic joint comprising rubber materials, said self-tightening elastic joints ensuring tightness of a connection between the container and the device, said joint remaining closed during filling, storing, installing and using of the container in the device, whereby the calibrating fluids maintain a constant concentration of saturating gases within said solution during storage, installation and use of the container.
