The viscometer allows us to measure the viscosity of liquids and assess their flow properties. This equipment has various applications and can be used in different substances and materials. For its part, viscosity can be defined as the resistance of the molecules that form a liquid, to separate, due to their adhesion forces. Monitoring this property is essential, as it affects the performance of the liquid. For example, during pumping or channeling, or their ability to submerge and coat other elements.

Viscosity belongs to the field of rheology, change of form and flow of substances, elasticity, viscosity and plasticity. Since viscosity is the measure of internal friction in a fluid, viscometers act as a tool within rheology. Viscometers have a place in many industries. These instruments are tested on fluids such as sauces, oils, and creams.

The pharmaceutical industry faces many challenges, as it must produce drugs with the highest quality standards at prices that are accessible to the population seeking to heal some ailment. In this sense, it is necessary to sustain intermediate and final quality parameters in the production process of drug manufacture, constantly making appropriate measurements.
