Viscosity measurement equipment
+ infoDynamic viscosity measurement for laboratory and industrial applications
Dynamic viscosity measurement is essential for evaluating how liquids and semi-solid materials resist flow under applied force. Accurate viscosity data supports product development, quality control and process optimisation across a wide range of industries.
Fungilab provides complete dynamic viscosity measurement solutions based on precision rotational viscometers, temperature control systems and specialized accessories designed to deliver reliable, repeatable and traceable laboratory results.
Whether measuring low-viscosity liquids or highly viscous materials, Fungilab offers instruments adapted to routine laboratory testing as well as demanding research applications.

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.
Complete laboratory equipment for dynamic and kinematic viscosity measurement
Viscosity measurement equipment includes all the instruments and accessories required to perform accurate viscosity testing under controlled laboratory conditions. Depending on the sample characteristics and the measurement method, laboratories may use rotational, capillary or falling-ball technologies supported by precision temperature control and calibration standards.
Dynamic viscosity measurement equipment
For measuring the dynamic viscosity of Newtonian and non-Newtonian fluids, Fungilab offers a comprehensive range of dynamic viscometers, including:
- Viscolead Series rotational viscometers.
- V-Series rotational viscometers.
- Falling-ball viscosity measurement systems.
Kinematic viscosity measurement equipment
For kinematic viscosity determination, Fungilab supplies precision capillary viscometers, including Ubbelohde and Cannon-Fenske models used in laboratories worldwide.
Measurement accessories
Specialised accessories allow laboratories to adapt viscosity equipment to different sample types and testing conditions.
- Small Sample Adapter (APM) for limited sample volumes.
- Low Viscosity Adapter (LCP) for low-viscosity fluids.
- HELDAL Unit for highly viscous materials.
- Thermosphere for elevated-temperature viscosity measurements.
Temperature control equipment
Because viscosity is strongly influenced by temperature, Fungilab provides heating circulators and refrigerated circulators to maintain stable thermal conditions and maximise measurement accuracy.
Calibration and quality assurance
Reliable laboratory testing also requires the use of certified viscosity standard oils, which provide traceable reference values for routine instrument verification and calibration.
