The surface tensions of propane (R-290) and isobutane (R-600a) were measured over the temperature range (253 to 333) K using a differential capillary rise method (DCRM) under vapor-liquid equilibrium conditions. The temperature and surface tension uncertainties were estimated to be within (10 mK and (0.15 mN.m-1, respectively. The present data were used to develop van der Waals-type surface tension correlations for propane (R-290) and isobutane (R-600a). Present results were compared with the available literature data.
