Broad Range Nano-liter Viscometer
Abstract: Classical rheological equipments working by capillary, rotational and falling/rolling ball techniques need amounts of material on the order of a mL. Micro-fabrication techniques that create micro-fluidic chan nels may use material volumes down to about twenty nL. However, these methods are typically valid for Newtonian flow regimes and low viscosities, which in general limit their usage as a general rheological tool. We have built a simple device without the need of microchannel technique that would require use of typically 10 nL material, but would work in a wide viscoelastic regime and allow optical observations and temperature regulation.
