Modular Microviscometer

Anton Paar’s Lovis 2000 M/ME modular microviscometer provides highly accurate viscosity determination from 400 μl sample volume. Results allow deep insights into the viscosity of liquids, offering accuracy up to 0.5 % and repeatability up to 0.1 %.

The microviscometer is available as a stand-alone instrument or in combination with a DMA M density meter for simultaneous determination of density, kinematic viscosity and dynamic viscosity. Manual operation requires only selection of the measuring method, sample filling and pressing “start”. Connecting a plug and play sample changer enables automatic measurement of up to 96 samples at the push of a button. Temperature control is quick and precise. Under optimal conditions, results are ready after 30 seconds.

The instrument is also a “lovis” rolling-ball rheometer. It provides the option of varying the inclination, which corresponds to the shear rate. The microviscometer therefore determines the shear rate dependence of low-viscosity liquids, which makes it suitable for zeroshear viscosity investigations. The instrument is specially designed for low-viscosity liquids but can be used for viscosity measurement on samples with a viscosity of up to 10,000 mPa.s, at any temperature from 5 °C to 100 °C.
