You probably know that rotational viscometers work by measuring the torque on a vertical shaft that rotates a spindle. The spindle is in the test sample and its rotation is impeded in proportion to the viscosity of the sample. These instruments measure viscosity.Read More

Nearly every day we have a question about differences between Viscosity, Consistency and Surface Tension. There is usually a second part of the question;Read More

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.

Not Much of a Science Person Learns About Viscosity
Since I joined CSC Scientific in July 2013, I’ve been on a steep learning curve. You see, I’ve never been much of a science person. There was even one particular chemistry class in high school used to give me migraine headaches - routinely.
Having no real background in the sciences means that I’ve had a lot to learn since I joined a company that sells scientific testing equipment. Maybe you’re nodding in sympathy with me right now. Many of our clients – that is, the people doing the purchasing on behalf of their company – are not scientists and don’t have a thorough knowledge of the scientific principles behind the products they’re told to buy.
