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 further.Read More

Customers Want Bostwick Consistometer Calibrations.
When told that CSC Scientific does not calibrate Bostwick Consistometers, people ask . “Then how can I calibrate my consistometer and where can I get a calibration standard?”.

The Bostwick Consistometer
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.

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.

At one end of the spectrum of the moisture world 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.

Many accessing our web site ask questions such as:
“How does water content affect water activity?”
"How is water activity different from water content?”
”Can I convert from moisture to water activity?”
I previously commented on water activity and now hope to clarify the differences between water activity and moisture content. Given that both of these measurements deal with water connected to a material, we must first understand of water content in a product.

Loss-On-Drying moisture analysis seemed like a simple process until, in a state of naïve bliss, I promised to look at evaporation, vapor pressure and bound water. While I was otherwise occupied with hese realities, I offered to enter the world of witchcraft and folklore; water activity.
