Viscometers occupy a vital place in biochemical laboratories and in the remote sensing and analysis of scientific data. These precision instruments act as flow resistance thermometers, measuring viscosity, i.e. the โ€˜thicknessโ€™ of liquids. Viscosity is determined by measuring the resistance of a liquid to being entrained or flowing under gravity or an applied force.

These devices offer detailed and accurate analysis of the composition and behavior of various substances within a controlled environment, thus providing vital information for various biochemical analyses.

Viscometers in operation

These laboratory instruments measure the viscosity of a fluid at various temperatures and pressures. There are different types of viscometers, each tailored to analyze various types of fluids and adapt to different testing environments. Some are simple and intended for quick and easy testing, while others are highly accurate and intended for more complex and detailed testing. Regardless of their type, they all work on the same principle: to measure the resistance that a fluid presents to flow.
