In addition, rheometers have a far broader shear measurement range, from 10 -6 to 10 5 s -1 which can be critical when mimicking production processes. While viscometers only measure viscosity, rheometers play a much more versatile role by characterizing flow, deformation, and tackiness of a material, inclusive of both Newtonian and non-Newtonian materials. These instruments exert a shear force on the material being tested. In order to accurately measure the viscosity of a material or product, a viscometer or a rheometer is typically used. Viscosity is the measure of a material’s resistance to flow and can be better understood as the friction between different molecules of the material. The viscosity of various pharmaceutical products including creams, ointments, syrups, suspensions, emulsions, coatings, gels, semi-solids, and biologics must be evaluated, monitored, and maintained between batches to ensure consistency with respect to both product production and performance. Understanding and controlling the viscosity of your material can be a critical step in its formulation-design space, manufacture, storage, and transportation.
