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.
Professional rotational viscometers for laboratory quality control
The Master Series viscometer is designed for laboratories that require precise viscosity measurements, advanced functionality and long-term reliability. Using the rotational measurement principle, these instruments determine dynamic viscosity by measuring the torque required to rotate a spindle immersed in the sample.
This measuring technique makes rotational viscometers suitable for analysing both Newtonian and non-Newtonian materials over a broad viscosity range.
