Our viscometers have redefined the way viscosity is measured with the benefit of  VROC® technology. All RheoSense viscometers require only small sample volume, control from low to very high shear rates, and measure true viscosity of  Newtonian and non-Newtonian liquids. Select your viscometer! Let's dig into the details.

Ink & Viscosity

Food and Beverages

Viscosity can play a big role with taste, texture, and even distinguish the difference between real and counterfeit products. Talk to a Rheologist

Polymers and Viscosity

Viscosity of all types of polymers can be essential ranging in a variety of industries. Intrinsic viscosity is a key application for polymers and bio-polymers.

Polymer Viscosity

Cannabis Viscosity

As the cannabis industry is growing both medical and recreational,  research and proper manufacturing involves accurate viscosity measurements.
Cannabis Viscosity

Cosmetics Viscosity

The viscosity of cosmetic plays an integral role in the formulation process, especially when it comes to quality control. 

Cosmetics Applications

Batteries Viscosity

Achieving optimal combination of viscosity (η) and the dielectric Constant (ε) helps researchers and battery engineers develop and also control the quality of batteries.Battery Applications

Extensional & Intrinsic Viscosity

"Darn, that little thing works great [microVISC]. Good job! I did a couple of known control samples, which measured bang-on exact with literature values. And then had no difficulties with my biological materials."

-Dr. David Krevor, Slip Chip

"Microfluidic 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."

- MIT's Gareth McKinley, Ph.D., and Chris Pipe, Ph.D.

"I would like to mention (m-VROC®) is a great instrument and I am really enjoying using it"

-Mahoom Fard, Canopy Growth
