What is it?
Viscosity is a measure of a fluid's resistance to shear flow and describes the internal friction of a moving fluid. The Brookfield Viscometer measures the dynamic viscosity of a fluid, which is the viscosity determined under shear conditions.

Why do we use it?
A change in viscosity of an emulsion is a sign that something is changing in the product composition. Therefore viscosity is a measure of the stability of the emulsion. VIscosity measurements are usually combined with some of the other test methods below to measure the effect of a temperature cycle or high temperature on an emulsion's stability.
How does it work?
The Brookfield Viscometer rotates a conical spindle at a precise speed through the emulsion sample. It measures the torque needed to overcome the viscous resistance caused by the sample fluid between the spindle and sample container.
