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.

What are the Primary Conditions Affecting Surface Tension?

One of the ways to describe surface tension in fluids is: the property of a liquid’s surface that resists force. It serves as a barrier to foreign materials and holds the liquid together. This ever-present property is caused by unbalanced forces on surface molecules that pull toward the main part of the liquid.

Which Type of Tensiometer do I Need?

As followers of these rants know, Fisher Scientific stopped offering its Tensiomat Tensiometer about a year ago. As a tensiometer manufacturer, we at CSC Scientific were very interestedin this and have tried to let the world know that we might be able to help with things such as replacement rings, trade-ins and the like.
