Guide and selection support
Viscosimeters are used in laboratories and industry to determine the flow properties of various types of liquids. They help to precisely analyze material characteristics and monitor process parameters.
The selection of an appropriate viscosimeter depends on the liquid to be measured, the measurement principle, and the required accuracy. Different types of viscosimeters are suitable for different applications and fluid types.
LabFinder supports you in navigating the range of viscosimeters and provides detailed information on application areas, measurement principles, and selection criteria for suitable measurement technology.
Application and Benefits
Viscosimeters are instruments used to determine viscosity, which is the resistance of a liquid to flow. Viscosity measurement is essential in research, development, and quality assurance for controlling the flow properties of chemicals, oils, foods, paints, and pharmaceutical products. They enable the characterization of both Newtonian and non-Newtonian fluids.
Selection Criteria
When selecting a viscosimeter, the properties of the liquid to be measured (e.g., Newtonian or non-Newtonian behavior), the required measurement range, sample volume, and the desired measurement method all play a decisive role. Aspects such as measurement accuracy, ease of use, and potential automation options are also important.
Types and Measurement Principles
Viscosimeters differ by measurement principle. Classic types include capillary viscosimeters, rotational viscosimeters, and falling ball viscosimeters. Devices operate using either shear rate or flow velocity as measurement parameters, thereby recording the dynamic or kinematic viscosity depending on the application.
Calibration and Maintenance
Regular calibration is necessary for reliable measurement results and is often performed with reference fluids of known viscosity. Maintenance steps include cleaning measuring cells and test components, as well as checking the mechanical and electronic parts.
Limits of Application
Viscosimeters can be limited when dealing with very complex rheological properties or highly time-dependent flow behaviors. For comprehensive rheological analysis, other devices such as rheometers are required. Extremely high or very low temperatures and aggressive chemicals may also restrict the use of certain types of viscosimeters.

Frequently asked questions
How does a viscosimeter work?
A viscosimeter measures the resistance of a liquid to movement. It records the force or time needed to set the liquid in motion or to move it through a measurement system, from which the viscosity is calculated.
What types of viscosimeters are there?
Common types include capillary, rotational, and falling ball viscosimeters. They differ in their measurement methods as well as their suitability for various types of liquids.
What should I consider when choosing a viscosimeter?
Important factors include the measurement principle, measurement accuracy, the type of liquid (Newtonian or non-Newtonian), as well as sample volume and ease of use.
Can viscosimeters also measure non-Newtonian fluids?
Yes, viscosimeters can also be used for non-Newtonian fluids; however, measurement results can vary and need to be interpreted depending on fluid type and measurement principle.
How often should a viscosimeter be calibrated?
Regular calibration using reference fluids, for example, is necessary to ensure accurate and reproducible results. The intervals depend on the device and frequency of use.
