The apparatus for p-V-T measurements of liquids and liquid mixtures was designed and tested. It works in the temperature range of 283 to 333 K and pressure range of 0,1 to 40 MPa with an overall accuracy of density measurement 1x 10-4 g cm-3. Its main part is a high-pressure vibrating tube densimeter working in a static mode. The apparatus was used for measuring the p-V-T relations of the heptane-1-chloropentane system. Excess molar volumes were calculated from the data and fitted to the Redlich-Kister equation.
