Cannon-Fenske Routine
Dynamic 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.

Kinematic Viscometer Types
CANNON-FENSKE
CANNON-FENSKE OPAQUE
ASTM D-445-446, ASTM D2515, ISO 3104-3105 and UNE 400313
Cannon-Fenske Opaque Viscometers (reverse flow type) are used for dark Newtonian liquids; especially suitable for liquids so dark in colour that cannot be seen in a Cannon-Fenske routine viscometer. Also used to study shearing stress and shearing rate. Sample volume: aprox. 12 ml. Precision: ±0.3%. Value indicated at 40ºC and 100ºC in both bulbs.
CANNON-FENSKE ROUTINE
ASTM D-445-446, ASTM D2515, ISO 3104-3105 and UNE 400313
Cannon-Fenske Routine Viscometers quickly and easily measure the viscosities of transparent Newtonian liquids. Sample volume: approx. 7 ml. Precision: ±0.2%. With constant value indication at +40 ºC and +100ºC.
All capillary viscometers are supplied with the calibration certificate issued in accordance with the conditions of accreditation granted by a National Metrological Register which has assessed the measurement capability of the laboratory, the test uncertainty and its traceability to recognized international standards UKAS.
Accessories
Today’s business world brings new challenges that demand innovative solutions. Fungilab’s aim, as a leading viscosity technology company, is to become an expertise partner in the viscosity world to offer you our best products and services.
To provide you and your customers with this necessary attention and an expertise support, Fungilab offers a wide range of products for the measuring of the kinematic viscosity of your products.
Our kinematic series include: the Höppler viscometer (falling ball), for the measurement of the low viscosity liquids in all industries; capillary viscometer series and baths, in accordance to ASTM and DIN methods, to obtain the most accurate viscosity of your liquids; and flow cup viscometers, suitable for paints, inks, varnishes and similar products.
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.
Glass capillary viscometers for transparent Newtonian liquids
The Cannon-Fenske Routine viscometer is specifically designed for measuring the kinematic viscosity of transparent Newtonian liquids. Its simple capillary design offers excellent repeatability, making it a preferred solution for routine laboratory testing and industrial quality control.
Manufactured from precision borosilicate glass, each viscometer is individually calibrated to provide reliable and traceable viscosity measurements throughout its service life.

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.
