We report on the construction and performance of a home-built viscometer employing a quartz tuning fork resonator as the sensing element. The resulting device allows measuring the viscosity of fluids in volumes as low as 300 μl, while controlling the temperature between -120 C and 150 C.
The capabilities and limitations of the viscometer are illustrated on the viscosity measurements of n-hexane (between -90 C and +50 C) and water (between 10 C and 90 C).
