m-VROC II Viscometer — Controlled Shear Rates and Small Samples

m-VROC II is the next generation of leading semi-automated, small sample viscometer. Capable of the most demanding applications including small sample protein therapeutics, m-VROC II features the widest dynamic range viscosity measurement with as little as 10 microliters of sample. The m-VROC II allows you to get the most out of your samples with the ability to retest and reuse a single sample for multiple measurements.

This product can be configured based on your applications and there are multiple chip options you can choose from. Here is the chip selection guide!

HOW IT WORKS

Understanding Fluid Behavior — Measuring Absolute Viscosity

With VROC® Technology, RheoSense took the standard principles of rheometry and created a dynamic micro-sample viscometer by adding microfluidics while reducing the size of the device with MEMS (micro-electrical mechanical systems) manufacturing. The result was a new platform which offers capabilities that are well beyond the limits of conventional viscometers in not only the sample volumes required, but the measurement range and precision.
