Accurate viscosity measurement at high
shear rates
The precisely micro-fabricated VROC, a "Viscometer/Rheometer-on-a-Chip", enables microLitre size samples to be used for high resolution, accurate and repeatable viscosity measurement
The small chip geometry extends viscosity measurements beyond conventional instrumentation limits into the realm of very high shear rates Although many industry processes involve very high shear flow, the viscosity of liquids is typically not measured at the shear rates experienced in these processes

New VROC - Viscometer/Rheometer-on-a-Chip
RheoSense, a developer of MEMS and Micron Sample Viscometry Instruments has introduced the VROC, a Viscometer/Rheometer-on-a-Chip
This is due to limitations in conventional instrumentation.
The VROC changes the measurement landscape allowing viscosity characterisation at the conditions occurring in actual applications.
Inkjet printers, for example, subject ink to shear rates in the range of 100,000 to 1,000,000 reciprocal seconds (1/s).
The VROC family type 'C' chip demonstrates viscosity measurements at greater than 250,000 (1/s).
Such a powerful chip is packaged in a small form factor allowing testing and cleaning in just minutes.
Viscosity measurements are faster and easier than ever with the VROC.
RheoSense is pleased to work with equipment manufacturers and OEMs to develop custom applications utilising VROC technology in Viscometry/Rheometry.
To receive additional information on the new VROC, please contact RheoSense.
