The HAAKE Viscotester 550 is specially designed for quality control applications. It is a rotational viscometer that measures precisely, quickly and simply the viscosity and flow behavior of liquid and semisolid test materials.

By its design, the Thermo Scientific HAAKE Viscotester 550 is a Searle viscometer. A rotational speed is preset and the flow resistance of the sample is measured, in other words, the torque required to maintain the set speed is proportional to the viscosity. From the torque required, the set speed and the geometry factors of the applied sensor, all final information on the viscosity, shear stress and the shear rate is calculated. The results are displayed digitally and can be printed simultaneously." [www.thermofisher.com]
