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.
Advanced rotational viscometers for professional laboratories
EVO Expert Viscometers are high-performance rotational viscometers developed by Fungilab for laboratories requiring accurate, repeatable and fully documented dynamic viscosity measurements. The instrument measures viscosity by determining the torque generated while rotating a spindle inside the sample at a controlled speed.
The EVO Expert platform combines precision measurement with advanced software functions, making it suitable for routine quality control, formulation development, research laboratories and industrial process monitoring.
Main features
- Colour TFT display with intuitive touchscreen interface.
- Wide speed range from 0.01 to 200 rpm.
- 54 programmable speed settings.
- Integrated temperature measurement using PT100 probe.
- Automatic range calculation (AUTO-RANGE).
- Automatic instrument verification (AUTO-TEST).
- Ramp, multistep and timed measurement programs.
- USB connectivity with optional wireless communication depending on the model.
Measurement ranges
The EVO Expert series is available in several measuring ranges to accommodate low, medium and high viscosity applications, allowing laboratories to select the most appropriate instrument according to their testing requirements. :contentReference[oaicite:1]{index=1}
Specialized accessories
The EVO Expert can be expanded with dedicated accessories for demanding applications:
- Small Sample Adapter (APM) for limited sample volumes.
- Low Viscosity Adapter (LCP) for low-viscosity liquids.
- HELDAL Unit for highly viscous products.
- Thermosphere for high-temperature viscosity measurements.
Temperature control and calibration
Reliable viscosity measurements require stable temperature conditions. EVO Expert viscometers can be used together with heating circulators and refrigerated circulators to maintain accurate thermal control during testing.
Routine instrument verification can be performed using certified viscosity standard oils, helping laboratories maintain long-term measurement accuracy and traceability.
Typical applications
EVO Expert viscometers are widely used in the food, pharmaceutical, cosmetic, chemical, paint, coating, adhesive and petroleum industries, where accurate dynamic viscosity measurement is essential for product quality and process control.
