microVISC - Portable Small Sample Viscometer
microVISC is the ultimate solution for your routine viscosity measurements. This portable and small sample viscometer is intuitively designed so that users can start operating within one minute. It employs RheoSense`s patented Viscometer/Rheometer-on-a-Chip (VROC®) technology and offers accurate and repeatable viscometry measurements, using sample size as little as 100 microliters.
Battery-operated and portable, microVISC™ can be deployed at any laboratory location or in the field. microVISC™ has been adopted by leading companies worldwide as their choice for quick, easy, and rapid viscometric measurements. High precision and accuracy saves time and resources.

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.
Scientific Principle
The measuring cell or “chip” contains a rectangular slit flow channel constructed of borosilicate glass, with a uniform cross-sectional area. The sample is injected at a constant flow rate though the flow channel where multiple pressure sensors mounted within the base monitor the pressure drop from the inlet to the outlet. The pressure drop is correlated with the shear-stress at the boundary wall. The shear rate and shear stress are directly related to the geometry of the rectangular slit and the flow rate which allow for viscosity measurements.
