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.

What are Liquid Properties? Why Should Anyone Care?

The first question is, "What are Liquid Properties?" Are they some kind of underwater real estate?

Contact Angle and Surface Tension - A Fascinating Liaison

Posted by Amanda Ranowsky on Apr 4, 2016 12:56:10 PM

Contact angle and surface tension. The two terms are never far apart. Run a Google search of "contact angle" right now and see for yourself. You'll often see the terms mentioned within a breath of one another because contact angle and surface tension are two approaches to surface analysis - the study of how a surface interacts with other materials or components. Generally speaking, there is also a relationship between the two measurements, one that tends not to be very clearly explained in other resources. I hope to remedy that today.

When Do I Need An Automatic Digital Tensiometer?

Posted by Art Gatenby on Dec 16, 2013 7:55:00 AM

 

Automatic digital tensiometers are expensive - three to four times more so than a high-precision manual tensiometer. We hope to clearly depict when an automatic digital tensiometer is not merely nice to have, but essential.

What are the Primary Conditions Affecting Surface Tension?

Posted by Art Gatenby on Sep 23, 2013 12:42:00 PM

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.

Surface Tension Measurement -- How High Is High Enough?

Posted by Art Gatenby on Mar 29, 2013 5:12:00 PM

I am regularly startled by little things that trigger new understanding about our slice of the instrument World.  This time it is about surface tension.
