“It doesn’t matter how it looks as long as it tastes good.”
This statement has long been my philosophy when it comes to cooking. The dishes I create (usually) taste okay – even really yummy, occasionally – but I stink at presentation.
Family and friends are usually quite forgiving when it comes to their sensory (sight, touch, smell) experiences with a food before the first bite. They tend to ignore looks and feel, and focus on taste.
Food buyers aren’t so forgiving. If their sensory experiences don’t meet expectations, that crucial first taste will never happen. Flavor isn’t everything, either. If the food doesn’t feel right, or pleasant, the first bite will also be the last.Read More

The answer to the question, “How Long Does a Water Activity Test Take?” is, as with most testing questions, “it depends.” Some water activity meters promise a test completed in a very short time; some in as little as five minutes. This time is an arbitrary selection that may or may not produce a satisfactory result.Read More
Looking at the rotational viscometers on the market today, you'd expect to see small price differences between the instruments offered by competing brands. But what if you find one viscometer priced at $2000 and another at $9000? Is the $9000 viscometer a better instrument? Why is there such a price difference between the two instruments?
Viscometer prices depend on both the make-up of the instrument's motor, and on the technical features of the instrument (temperature probe, speed range, USB compatibility, etc.). There are two main types of rotational viscometers: those using a spring motor, and those using a servo motor.
In this article, I’m going to take a look the options available for rotational viscometers, and how those options affect the price.Read More
Most rotational viscometer specifications promise high test accuracy and repeatability. However, an instrument on its own cannot guarantee accurate results. Instrument set-up and using the right test parameters are critical pieces of the puzzle.
Test parameters and turbulence are two key factors to consider when preparing to test with a rotational viscometer. The spindle, speed setting, and temperature of the product are some of the parameters that can impact test results. Additionally, turbulence in the sample’s flow during a test will distort viscosity readings. Knowing how to manage these two factors can significantly contribute to the accuracy of your testing.Read More
Contact angle and surface tension. The two terms are never far apart. Run a Google search of "contact angle" right now and see for yourself. You'll often see the terms mentioned within a breath of one another because contact angle and surface tension are two approaches to surface analysis - the study of how a surface interacts with other materials or components. Generally speaking, there is also a relationship between the two measurements, one that tends not to be very clearly explained in other resources. I hope to remedy that today.Read More
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.Read More
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.Read More
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.
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:
