Cannon 9722-H74 Ubbelohde 400 Semi-Micro Calibrated

Cannon 9722-H74 Ubbelohde 400 Semi-Micro Calibrated

The Cannon 9722-H74 Ubbelohde 400 Semi-Micro Calibrated is designed for accurate measurement of kinematic viscosity in small volumes of transparent Newtonian liquids. It complies with ASTM D445 and ISO 3104 standards; therefore, laboratories can perform viscosity testing according to internationally accepted procedures. Moreover, its semi-micro construction allows efficient testing while maintaining high precision and repeatability.

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 throughout repeated analyses. Furthermore, because the viscometer constant is identical at all temperatures, laboratories benefit from simplified calculations and consistent performance across various testing conditions.

Features

First, the instrument accurately measures kinematic viscosity within the 240 to 1200 cSt range.
Moreover, it requires approximately 1 mL of sample, although sizes 400–600 may require slightly larger volumes.
In addition, it supports intrinsic viscosity determination with dilution up to 20 mL, which is particularly useful for polymer solution studies.
Furthermore, it is fully calibrated and supplied with a certificate of calibration and instruction sheet to ensure traceable measurement results.
At the same time, precision borosilicate glass construction provides excellent chemical resistance and durability.
Finally, the 200 to 1000 second flow time range enhances measurement resolution and consistency.

Applications

Primarily, this viscometer is ideal for analyzing higher-viscosity liquids such as heavy lubricants, oils, and specialty petroleum products. Additionally, it supports polymer research laboratories conducting intrinsic viscosity measurements. Likewise, industrial quality control laboratories rely on this model for accurate, repeatable, and traceable viscosity testing. Because it combines semi-micro efficiency with a high viscosity range, it is particularly suitable for advanced laboratory environments handling medium-to-high viscosity fluids.,
