A Sieve Shaker's Passing From Noise To Quiet

Posted by Art Gatenby on Oct 26, 2016 2:26:45 PM

Quiet Sieve Shakers

Recently in a quiet, reflective moment, I recalled my first work with sieve shakers. Horizontal motion with tapping was the basic shaker design. The Ro-Tap® was King, and there were few alternatives. Different shakers for special applications, such as the Mary Jane and one that was hung from the ceiling, were the exception.

A Spotlight on Rotational Viscometers

Posted by Art Gatenby on Oct 3, 2016 10:45:00 AM

You probably know that rotational viscometers work by measuring the torque on a vertical shaft that rotates a spindle.  The spindle is in the test sample and its rotation is impeded in proportion to the viscosity of the sample. These instruments measure viscosity.

Should You Move to "Actual" Surface Tension?

Posted by Art Gatenby on Sep 8, 2016 4:31:38 PM

An understandable definition of surface tension: The attraction force between molecules at the surface of a liquid. The force that keeps if from flying off into space.

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 a Consistometer vs. a Viscometer?

Posted by Amanda Ranowsky on Jan 29, 2016 2:58:00 PM

One of the most frequently asked questions we get is, "How can I get a viscosity reading from the Bostwick Consistometer?" The answer is, "You can't.We've elaborated on this in other articles. We've even got a great infographic to explain the difference. With this article, I hope to advance the understanding of the difference between these concepts even futher.
