How Are Consistency, Surface Tension and Viscosity Different? 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. Here at CSC, we work with Consistency, Surface Tension and Viscosity of liquids... read more. |
Surface Tension and Interfacial Tension
I was musing, the other day on the designs of two ring tensiometers. One of them is called an interfacial tensiometer and the other simply a tensiometer. The plain tensiometer works only with an upward pull and the interfacial works with both an upward pull as well as a downward push. Before I get to my question a couple of definition might be useful... read more. |
Is Consistency Viscosity? Not Really!
We make the Bostwick Consistometer. The Bostwick is used extensively to measure the consistency of sauces and condiments. It has strong application in the quality control departments of ketchup and mustard producers. Results from a Bostwick Consistometer have been used for more than six decades to control the quality of many of the foods you use... read more. |
How Can I Measure Viscosity? The answer, like most answers in the measurement world, is it depends. To find out what it depends on we'll start with defining viscosity... read more.
As followers of these rants know, Fisher Scientific stopped offering its Tensiomat Tensiometer about a year ago. As a tensiometer manufacturer, we at CSC Scientific were very interestedin this and have tried to let the world know that we might be able to help with things such as replacement rings, trade-ins and the like... read more.
Read more Surface Tension articles here.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... read more.
