Cannon 9722-H50 Ubbelohde 25 Semi-Micro Calibrated

The Cannon 9722-H50 Ubbelohde 25 Semi-Micro Calibrated is specifically developed for highly precise measurement of kinematic viscosity in small volumes of transparent Newtonian liquids. It complies with ASTM D445 and ISO 3104 standards; therefore, laboratories can confidently perform viscosity testing according to internationally recognized procedures. Moreover, its semi-micro design significantly reduces sample consumption while maintaining excellent analytical accuracy.

In addition, the suspended-level Ubbelohde design ensures that the viscometer constant remains independent of liquid head pressure. As a result, measurements remain stable and reproducible across repeated tests. Furthermore, because the viscometer constant is the same at all temperatures, laboratories benefit from simplified calculations and consistent performance.

Features

First, the instrument accurately measures low-range kinematic viscosity from 0.4 to 2 cSt.
Moreover, it requires only approximately 1 mL of sample, which is ideal for limited or high-value materials.
In addition, it supports intrinsic viscosity determination with dilution up to 20 mL, making it suitable for polymer solution analysis.
Furthermore, it is fully calibrated and supplied with a certificate of calibration and instruction sheet for traceable measurement results.
At the same time, its precision borosilicate glass construction ensures excellent chemical resistance and long-term durability.
Finally, the constant remains identical at all temperatures, improving testing convenience and reliability.
