Why Test for Viscosity in Food

Posted by Art Gatenby on May 6, 2015 4:35:00 PM

When people hear of viscosity for the first time, invariably they ask these three questions:

Is In-Line Moisture Measurement For You?

Posted by Art Gatenby on Feb 27, 2015 9:59:54 PM

Five years ago, we published an article on in-line vs. off-line moisture measurement. At that time we debated whether these measurement systems should be called on-line or in-line. We chose to use the term "on-line". Since then, however, the world of the internet became known as "online". So, to avoid confusion, we changed our view and now refer to direct measurement as "in-line" moisture measurement.

What is the Difference Between Dynamic and Kinematic Viscosity?

Posted by Amanda Ranowsky on Jan 15, 2015 6:31:24 PM

I’m always trying to find a simple vision of the material testing world. When I was assigned to our new Viscosity product line, I thought I’d found it. Then I was introduced to the concepts of the dynamic and kinematic factors of viscosity.

This is my attempt to bring clarity to these two principal ways to measure viscosity.

What's So Special About Picking A Sieve Shaker?

Posted by Art Gatenby on Jan 6, 2015 9:15:00 PM

If you take Sieve Shakers for granted, you may be surprised to know that the selection of the right shaker can have a profound effect on your sieving results.

Viscosity, Consistency and Surface Tension - What Are These Things?

Posted by Art Gatenby on Aug 27, 2014 12:56:00 PM

Nearly every day we have a question about differences between Viscosity, Consistency and Surface Tension. There is usually a second part of the question;

When is a Sieve Not a Sieve?

Posted by Amanda Ranowsky on Jul 17, 2014 5:00:00 AM

In our business, we use the word “sieve” to describe a piece of equipment that separates desired elements from unwanted material using a woven wire screen or mesh net. To others, “sieve” can mean something very different.

Dance Bars, Music Technology, and...Surface Tension?

Posted by Amanda Ranowsky on Jul 8, 2014 12:39:00 PM

What do an Irish music technology developer, a British manufacturer of arcade and retro-style furniture, and a dance bar in San Francisco have in common? Given a million guesses, I’d never have thought of this:

How Wide Is The Moisture Measurement World?

Posted by Art Gatenby on May 13, 2014 6:26:00 PM

At one end of the spectrum is the classic Speedy Moisture Tester where you use the reaction of water with calcium carbide to cause a mini explosion resulting in a moisture measurement reading. This method is used frequently for soils, concrete, and other like materials.

How To Fix An Abused Bostwick Consistometer

Posted by Art Gatenby on Apr 2, 2014 2:49:00 PM


Which looks more durable to you?

The value of a Bostwick Consistometer is that it’s easy to use, which makes it simple to do repeatable testing. The Consistometer is made of stainless steel. One would think that this means a long and useful life. However, as I regularly discover, the real world often defies theory.

A Consistometer’s value is diminished if its leveling plate and screws get bent out of alignment. The story that follows tells how people in the real world handle, or mishandle, this instrument, and what can be done to save it.
