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.

Don’t Worry - Karl Fischer is Easy

Posted by Art Gatenby on Nov 16, 2015 5:25:25 PM

When we first started measuring moisture with Karl Fischer,I was instructed in the complex chemical reactions involved. I was also was told that the process was skittish.
