Description
The Cannon-Ubbelohde viscometer with capillary No. 200 is intended for kinematic viscosity determination in the measuring range 20–100 mm²/s and works with a constant K of 0,1. It is specified as a Cannon-Ubbelohde A + Dil. B capillary instrument and is supplied uncalibrated, making it suitable for laboratories that apply their own calibration protocols or internal reference standards. The suspended-level capillary geometry supports timing of liquid flow between the engraved marks once thermal equilibrium is reached in a thermostatic bath, and the result is largely independent of the exact sample volume charged into the instrument. Offered as a single piece with a net weight of 0,118 kg from manufacturer Witeg, this model belongs to the mid-range capillary series used for transparent Newtonian liquids in quality control, research and routine analytical work. Capillary No. 200 bridges lower- and higher-viscosity applications within the Cannon-Ubbelohde family, allowing laboratories to match instrument constant and measuring range to the expected sample viscosity. When combined with a suitable stopwatch or automatic detection system and a stable temperature bath, the design supports reproducible meniscus timing for comparative viscosity studies and method development.

Questions about Viscometers Cannon Ubbelohde A + Dil.B
What is this article?
Viscometers Cannon Ubbelohde A + Dil.B 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.
