A sealed package for calibrating a testing instrument with a fluid calibrated at a preselected temperature, the fluid being normally subject to permanent, unpredictable interaction with its surrounding environment due to permeation, diffusion and chemical reaction during the packaging process, shelf storage, the dispensing process or the use cycle, the package comprising rigid, hollow vessel of nonpermeable material, at least one end of the vessel terminating in a sealed port and a calibration fluid partially or completely filling the vessel and having the above-enumerated characteristics. Means for filling and sealing the packages and for calibrating instruments, e.g., blood gas analyzers, with them are also disclosed. |
