Description
Cannon-Fenske viscometer 100-500 is a glass capillary instrument for determining the kinematic viscosity of opaque liquids in the measuring range 100–500 mm²/s. It follows the Cannon-Fenske design for non-transparent media and is fitted with capillary number 350. The stated constant L is 0,50 mm²/s², enabling calculation of kinematic viscosity from measured efflux times under controlled bath conditions. Overall length is 295 mm, giving a compact tube geometry suited to standard laboratory viscosity baths and holders. Supplied as 1 pc with a net weight of 0,091 kg, the unit is intended for routine quality control, formulation work and research applications involving dark oils, process fluids or other light-absorbing samples where reverse-flow Cannon-Fenske geometry is preferred. This model from manufacturer Witeg supports comparative viscosity work within the stated 100–500 mm²/s window when used with appropriate timing and temperature control. Laboratories can integrate the capillary into existing opaque-media workflows without changing established Cannon-Fenske handling practice.

Questions about Viscometer Cannon Fenske 100-500
What is this article?
Viscometer Cannon Fenske 100-500 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Viscometers, inside Density & viscosity measurement, in Lab instruments.
A capillary viscometer times the flow of a liquid through a tube. A rotational viscometer twists a spindle in the liquid. Both need a stated temperature. Kinematic and dynamic viscosity are different numbers. The capillary size has to put the flow time in the range the method allows.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
