Automatic digital tensiometers are expensive - three to four times more so than a high-precision manual tensiometer. We hope to clearly depict when an automatic digital tensiometer is not merely nice to have, but essential.

Break the Curse of Particle Size Calculations
Every now and then I’ve had to calculate the results of a sieve test: I’d get the sieves and sample loaded on the shaker, run the shaker, then realize I’d have to start over because I forgot to get the empty weight of each sieve. Or I’d have to carefully brush out the sample onto a balance.

Chapter One:
Jim’s life was dull. So, so dull. He spent his days surrounded by piles of sieves – his glamorous job was to calculate the ratio of particles left in the sieves of each stack after a sample of his company’s product was run through the stack using a sieve shaker. It was a job much like the one his cousin Hiram had, although he seemed to remember hearing that Hiram had found an easier way to do it.

A question we get a lot is:
“How do I determine the moisture in my product?"
Of course, the answer is often “it depends”, and the method does depend on the chemical and physical composition of the product. There are several methods used to determine moisture content: Loss-on-Drying (also known as Weight Loss), Karl Fischer, NIR, and Radio Frequency.

One of the ways to describe surface tension in fluids is: the property of a liquid’s surface that resists force. It serves as a barrier to foreign materials and holds the liquid together. This ever-present property is caused by unbalanced forces on surface molecules that pull toward the main part of the liquid.

I am regularly startled by little things that trigger new understanding about our slice of the instrument World. This time it is about surface tension.

I am very excited about a new update to the CSC Digital Moisture Balance. To give you a perspective of why I’m excited about this Moisture Content Analyzer update, I thought you my be interested in the story of the transition from a classic mechanical moisture analyzer to the current highly robust and durable electronic instrument of today.

As you know the Karl Fischer Method of moisture analysis has a reputation of being water specific. The method works through the use of a special Karl Fischer Reagent.
