Viscometer Cannon- Ubbelohde For Transparent Liquid

The Cannon-Ubbelohde Viscometer is a high-precision instrument used for determining the kinematic viscosity of transparent Newtonian liquids under gravity flow, as specified by ASTM D446. This design features a vertically mounted, suspended-level capillary tube with a side arm that remains open to the atmosphere, eliminating the influence of back pressure during measurement.

Made from chemically resistant borosilicate glass, the viscometer provides high accuracy and reproducibility in temperature-controlled environments. The clear construction allows precise visual timing of fluid flow between calibrated marks. It is widely used in laboratories for quality control, research, and product development in the chemical, petroleum, and pharmaceutical industries.
