Liquid Surface Tension and Interfacial Tension Between Liquids

I was musing, the other day on the designs of two ring tensiometers. One of them is called an interfacial tensiometer and the other simply a tensiometer. The plain tensiometer works only with an upward pull and the interfacial works with both an upward pull as well as a downward push. Before I get to my question a couple of definition might be useful.

Surface Tension by duNouy Rings or Wilhelmy Plates – Which to Choose?

Posted by Art Gatenby on Jul 16, 2018 5:34:18 PM

When tempted to think I know all there is about surface tension measurement, further information brings me back to earth. I’m conversant with the principal applications: surfactant analysis, plating, detecting contaminants, development of ink and the like. I have assisted customers to set up and calibrate duNouy Ring tensiometers for most applications -- all the while taking for granted that the Ring technique was the method of choice -- with only infrequent questions arising about Wilhelmy Plate tensiometers.
