Viscometers are used by the food industry to ensure the consistency and quality of liquid foods. Zwick Roell claims its new tester provides what the company claims is an economical alternative to ...

A recent study used various gas oils and blends with residual heavy oils in order to evaluate the predictability of four different correlations. The gas oils differed substantially in their ...

Brookfield Engineering, the world standard for viscosity measurement and control, offers its Practical Course on Viscosity Measurements. This popular course is designed to help Brookfield viscometer ...

There is a strong link between what is called the weight-average molecular weight of a polymer and a parameter called the zero-shear viscosity. Although the correct link rather depends on the polymer, ...

Traditional methods for measuring IV of hygroscopic polymers involve dissolving the polymer in halogenated solvents such as chlorinated phenols and comparing the flow time of the solution with that of ...

Viscosity, or a fluid’s resistance to flow, is independent of the rate of shear or shear stress, at a given temperature, for Newtonian fluids. Non-Newtonian fluids such as polymer solutions often ...
