FIELD: study of physical and chemical properties of liquids. SUBSTANCE: third hopper is vacuum-tight joined in pycnometer to right hopper of the two upper hoppers, perpendicular to it. Third hopper carries starting material for study encapsulated in ampoule and has striker to open it. Lower end of right measuring capillary is joined to lower working chamber at level of its bottom. Technical result of invention lies in improved conditions for thermal vacuum treatment, in simplified filling of working chamber with analyzed liquid without formation of any breaks in column of liquid in capillaries and cavities in volume of liquid, in increased efficiency, reliability and accuracy of measurements. EFFECT: increased efficiency, reliability of accuracy of measurements. 2 dwg
