Abstract

New apparatus for measuring parameters such as pH, pCO.sub.2, pO.sub.2, and Hb content of physiological fluids, especially blood, is described. The apparatus comprises novel means for suspending reagent vessels (34, 35, 40, 45, 50) having shoulders (51, 52) and containing calibrating solutions, rinsing solutions etc., as well as for suspending a liquid waste vessel (26) by suspending the vessels between rods (53, 54) fed to the analyser. The reagent vessels are provided with caps (55, 58) at the top and include liquid reagent conduit extending from the outlet aperture of the cap down into the liquid. When the vessel is mounted on the analyser a fixed inlet tube extending horizontally outwardly from the analyser penetrates a seal across the outlet aperture and connects with the liquid reagent conduit.
