For micron sample R&D
"Micro-fluidic devices offer several advantages compared to conventional rheometers in that they only require small volumes of fluid sample, they can impose high deformation rates without entering strongly inertial flow regimes, the absence of a free surface avoids evaporation, and they can potentially be used as a simple, disposable flow-through device."

For at- line high shear application
"The VROC provides more measurement than conventional viscometers. This additional measurement is a key part in understanding the properties of polymers made by CP Kelco. It is capable of making measurements not possible with other instruments. Rotational instruments fail to deliver accurate measurements at these high shear rates and the capillary flow method is preferred. The ability of the RheoSense instrument to measure very small sample quantities is also useful. We have found the instrument to be accurate and reliable."

For online application
"We have used the system extensively, with great success. From the operational viewpoint, there is a clear advantage in seeing real-time data. This advantage allows us, the end-user, the ability to diagnose problems within a live systems, as well as seeing the effects of manipulating the outputs for control, or for information for further analysis and calculations."
