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.

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.

I used to think that liquids were pretty simple things. Is that what you think too?

Not so fast. Let’s take a look at three properties of liquids and see if we change our view.

How Do I Set Up A Bostwick Consistometer?

Posted by Art Gatenby on Oct 23, 2013 8:30:00 AM

 

We get the same two questions almost every week about the CSC Bostwick Consistometer:

             1) What angle do I use to set it up?

             2) How do I level the Consistometer?

The principle of the CSC Bostwick Consistometer is based on the slump cone. In this procedure, a cone is filled with the material to be tested. It is then set on a level surface with the open area facing downward. The cone is pulled away and after a fixed time, the amount that the material slumped is measured.  The thicker the material, the less slumping occurs.

Who Beats Up Your Bostwick?

Sometimes we encounter a product that is so simple and rugged that it would be tempting to deem it indestructible. Consider a stainless steel trough with a gate and etched numbers on the bottom. Seems simple and the stainless would make it tough, right? That is not the case, but it has survived nearly unchanged for more than 85 years.

The Bostwick Consistometer is used all over the World to check the quality of sauces and condiments. In our in-house training session we do blind product tests and clearly define the differences between brand of ketchup and mustard. This is a testament to the value placed on Bostwick Consistometer tests by the top food manufacturers.
