An accurate, nonintrusive method is described to measure the dynamic tension of dilated liquid-liquid interfaces. In this method, the time-dependent pressure difference across the curved interface of an expanding spherical drop, immersed in the second immiscible phase, was measured as a function of

The maximum liquid drop volume (v(max)) is measured by using a back-suction micrometer syringe piston technique. Different very viscous liquids are measured by (v(max)) and (v(f)) methods to observe the effect of viscosity on tension measurement. No apparent viscosity effect was observed in surface
The maximum liquid drop volume (nu(max)) is measured using a back-suction technique with a micrometer syringe piston. The residual amount of liquid on the tip was determined and the tension data calculated from the theoretical correction factors are well in accordance with those from the falling dro
