Cannon 9722-H77 Ubbelohde 450 Semi-Micro Calibrated

Cannon 9722-H77 Ubbelohde 450 Semi-Micro Calibrated

The Cannon 9722-H77 Ubbelohde 450 Semi-Micro Calibrated is specifically designed to measure the kinematic viscosity of small samples of transparent Newtonian liquids with high precision. It complies with ASTM D445 and ISO 3104 standards; therefore, laboratories can perform viscosity testing according to internationally accepted procedures. Moreover, its semi-micro configuration minimizes 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, the instrument delivers stable and highly reproducible flow time measurements. Furthermore, because the viscometer constant remains the same at all temperatures, calculations are simplified and consistency is maintained across various testing conditions.

Features

First, the instrument accurately measures kinematic viscosity within the 500 to 2500 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 analysis.
Furthermore, it is fully calibrated and supplied with a certificate of calibration and instruction sheet to ensure traceable and reliable 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 resolution and repeatability of viscosity measurements.

Applications

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