RheoSense (USA) is now introducing the VROC™; a highly accurate flow through viscometer and rheometer. This MEMS manufactured device characterises complex liquids from miniscule 50 micro litre samples in a closed system design that eliminates contamination and solvent evaporation, measures faster and more accurately, greatly facilitates
online high throughput processing and production, integrates easily into larger systems. The VROC™ is an enhanced rheology device with more
capabilities than conventional instruments. The functional differences are produced by hybrid micro-fluidic and electronic interfaces that in combination with the small form factor make the VROC less vulnerable error inducing variables. This enhanced accuracy is validated by the fact that the VROC™ easily characterises complex liquids even during high shear measurement (one of the most challenging measurements for viscometers and not possible with rheometers). If you have used conventional capillary and rotational instruments for this measurement you know the problem.

VROC™ provides the extra information because much easier to complex liquids like inks, API’s, Oligomers and other which benefit from accurate characterization. With the VROC you can accurately measure ‘true’ viscosity, temperature and pressure with one instrument.
In summary, the VROC™ is a robust, flexible and adaptable rheology device which is perfectly designed for challenging and high throughput manufacturing applications. The accuracy and speed of the VROC technology could revolutionise high throughput manufacturing in the petroleum, biopharmaceutical and chemical industries.
