Irreversible adsorption of protein molecules at the interface. No Viscoelastic characterization. When measuring viscosity, it is important to know if the fluid you are working with is Newtonian or non-Newtonian. Viscosity of Newtonian fluids is constant and therefore independent of shear rate whereas the viscosity of non-Newtonian fluids is not constant and therefore dependent on shear rate.

And, often only approximate the apparent properties of fluids , failing to quantify the absolute or true viscosity, which is one of the most important parameters in the development and modeling of applications that involve fluid flow. Behavior of Non-Newtonian fluids affects both production and how they are applied ex: injectability, lubrication, spreading, jetting or drinking. VROC combines microfluidic and MEMS Micro-Electro-Mechanical Systems technologies to measure dynamic viscosity over a wide dynamic range of operation, delivering data with the highest accuracy and repeatability.

Positive displacement pumps are the recommended pump when handling viscous fluids.

They operate at lower speeds and transfer lower amounts of shear energy to the fluid in comparison to a centrifugal pump. Based on your application, there are a wide variety of positive displacement pumps that are appropriate. Viscosity is a crucial factor in determining the friction loss, due to the shear energy in a fluid process system. It is also important to understand as you select the size of valves, filters, instrumentation and piping.

Global Pumps have put together a typical list of viscosities. These will help you determine exactly what the viscosity is of the fluid you are pumping.
