APPARATUS ADAPTED TO PERFORM A PLURALITY OF DETERMINATIONS ON WINE SAMPLES OR THE LIKE

摘要

An apparatus performs a plurality of determinations on wine samples or the like thanks to a sample (8), which is based on a combined pH probe (8, 14, 16); this probe comprises a membrane (17), which is flat, gas permeable, with a thickness comprised into a range of 5-100 micron and which co-operates with an electrochemical glass bulb (16). In order to allow the diffusion of gaseous compounds of a wine sample through the glass bulb (16) into an internal solution a substantially complete adhesion of the membrane (17) is obtained on the flat surface of the glass bulb (16), which protrudes with a projection (H) allowing a stretching action of the membrane (17) on such flat surface.
