Following the launch of the new m-VROCi, Viscometer/Rheometer On a Chip, at Pittcon 2014, Malvern Instruments will focus on the unique technology of this system and the considerable benefits it delivers in a webinar on 16 April 2014. The m-VROCi provides safe, accurate viscosity measurement for low viscosity industrial fluids, under conditions that reflect those that apply during end-product use.

Malvern’s webinar will show how the innovative microfluidic technology at the heart of the m-VROCi works. The presenters will explore how the instrument meets an established need within industry for accurate and robust measurement of low viscosity formulations, most especially at ultra-high shear rates. Other benefits of the m-VROCi system include completely enclosed measurement for safe and reliable analysis of highly volatile or environmentally-sensitive samples, and the generation of accurate viscosity data using sample volumes as low as 50 µL, essential for scarce or high value materials. A wide dynamic range, easy sample loading and repeatable, accurate measurement further enhance the suitability of the m-VROCi for a wide variety of industrial applications.
The m-VROCi determines fluid viscosity by measuring the drop in pressure that occurs as a fluid travels through a microfluidic channel. Micro Electro Mechanical System (MEMS) pressure sensors embedded within the channel provide highly accurate pressure measurement. Smart control software then uses the relationship between the pressure drop, flow rate and viscosity to construct flow curves - plots of viscosity as function of shear rate. These provide information about the way a fluid will behave under specific process conditions, information that can be used to improve the performance of industrial processes and the products they manufacture.
