Kinematic viscosity is a measure of a fluid’s resistance to flow under the influence of gravity. It’s defined as the ratio of the fluid’s dynamic (absolute) viscosity to its density. In other words, it describes how thick or thin a fluid is without the involvement of any external force except gravity.
Professional kinematic viscometers for laboratory applications
Kinematic viscometers determine the kinematic viscosity of transparent or opaque liquids by measuring the time required for the sample to flow through a calibrated glass capillary at a precisely controlled temperature. The measured flow time is converted into kinematic viscosity using the calibration constant of the viscometer.
This measurement technique is widely recognised for its excellent accuracy and repeatability, making it the preferred method for lubricant analysis, petroleum testing and many laboratory quality control procedures.
Fungilab capillary viscometer range
Fungilab offers several types of capillary viscometers to suit different applications:
- Ubbelohde viscometers.
- Cannon-Fenske Routine viscometers.
- BS/U-Tube viscometers for transparent liquids.
- BS/U-Tube viscometers for opaque liquids.
Precision temperature control
Accurate temperature control is essential because kinematic viscosity is highly temperature dependent. Fungilab provides the THERMOCAP precision bath, specifically designed to maintain exceptional thermal stability during capillary viscosity measurements.
Applications of kinematic viscometers
- Lubricating oils.
- Petroleum products.
- Hydraulic fluids.
- Industrial oils.
- Fuels.
- Chemical products.
- Research laboratories.
Calibration and verification
To maintain laboratory measurement quality, kinematic viscosity systems can be verified using certified viscosity standard oils. These reference materials help ensure traceability, instrument performance and long-term measurement reliability.
Kinematic versus dynamic viscosity
Kinematic viscosity measures the resistance of a liquid to flow under gravity, whereas dynamic viscosity measures the force required to move one layer of fluid over another. For dynamic viscosity measurements, Fungilab also manufactures professional rotational viscometers suitable for both Newtonian and non-Newtonian materials.
Frequently asked questions about Kinematic viscometers
What is a kinematic viscometer?
