Surface Tension - Rings, Bubbles, Drops, and Plates

Posted by Art Gatenby on Feb 19, 2019 8:00:00 AM

The definition of Liquid Surface Tension is simple.  

It's the force that keeps a liquid from flying off into space.

However, the measurement of surface tension can take many forms, which can be confusing. In an attempt to get some clarity, we have articulated two principle measurement concepts in this article: drop-based measurement and force-based measurement.

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.
