Dynamic viscosity
Viscosity is part of the science of Rheology which quantifies the resistance materials give to changing shape.
Proper interpretation of viscosity data can reduce the rate of rejects while keeping production and formulation development costs to a minimum. Consistent product quality is ensured through proper viscosity measurements, either alone or in conjunction with compatible tests.
Dynamic viscosity testing can help with:
- Material characterization or “finger-printing”
- Standard testing methods to check for differences between batches
- Indirect way of measuring quality
- Product formulation
- Quality control
- Process control
- Design, optimization and operation of process equipment

Newton’s Law
According to Newton’s law, the viscosity of a fluid is constant. As shear rate changes, shear stress changes in proportion such that viscosity is constant. Common fluids that exhibit such behavior are:
Unfortunately for us, not all fluids follow Newton’s law. In fact, most fluids do not. For this reason, fluids are classified into two categories:
Rotational Viscometer
The viscosity is calculated from the measured torque and rotational speed, as well as the dimensions of the measuring geometry.
A fluid’s resistance to flow is measured by the torque it exerts on the rotating shaft of the viscometer.
Absolute viscosity: the measuring geometry fulfills certain requirements (which is the case of coaxial spindles).
Relative viscosity: the dimensions of the measuring geometry are not well defined.
Advantage
Flexibility in:
- Viscosity Range
- Temperature range
- Shear rate range
Application
For Newtonian and non-Newtonian substances and temperatures different from room temperature.

Calibration and traceability
Every Cannon-Fenske Routine viscometer is individually calibrated under the requirements of a National Metrological Register, ensuring measurement traceability and confidence for laboratory testing.
For optimum measurement accuracy, viscosity tests should be performed under controlled temperature conditions. The THERMOCAP precision bath provides the temperature stability required for accurate capillary viscosity measurements.
Alternative capillary viscometers
When testing dark or opaque Newtonian liquids, the Cannon-Fenske Opaque reverse-flow models provide the appropriate solution. Fungilab also manufactures BS/U-Tube viscometers for transparent liquids, BS/IP/RF U-Tube viscometers for opaque liquids and Ubbelohde viscometers for different laboratory requirements.
Typical applications
Cannon-Fenske Routine viscometers are widely used for measuring the kinematic viscosity of lubricants, petroleum products, solvents, chemicals and many other transparent Newtonian liquids in laboratory and industrial environments.
Fungilab can recommend the most suitable viscometer constant according to the expected viscosity range, sample characteristics and applicable testing standard.
