A modified static apparatus for measuring the vapour liquid equilibrium data is described. It is a modification of the apparatus originally proposed by Surovy and Dojcansky (1974). The construction alterations applied to the apparatus improve and simplify its functioning. It is checked on measuring three binary systems: benzene - n-heptane, cyclohexane - cyclohexanone and benzene - 2-propanol. The agreement of the experimental and tabulated data proves the suitability of the apparatus for obtaining the V-L equilibrium data.
