Cannon 9722-G77 Ubbelohde 450 Semi-Micro Uncalibrated

Cannon 9722-G77 Ubbelohde 450 Semi-Micro Uncalibrated

The Cannon 9722-G77 Ubbelohde 450 Semi-Micro Uncalibrated is designed for precise measurement of kinematic viscosity in small volumes of transparent Newtonian liquids. It complies with ASTM D445 and ISO 3104 standards, ensuring reliable and internationally recognized testing performance. This semi-micro model is ideal for laboratories that require accurate viscosity analysis while minimizing sample consumption.

The Ubbelohde suspended-level design improves measurement stability because the viscometer constant remains independent of liquid volume. As a result, it provides consistent and reproducible flow time readings, especially for research, quality control, and polymer solution analysis.

Features

The instrument measures kinematic viscosity of transparent Newtonian liquids with high repeatability.
Its semi-micro construction allows testing with very small sample volumes, reducing material waste and cost.
The suspended-level Ubbelohde design ensures improved accuracy and independence from hydrostatic pressure variations.
It supports intrinsic viscosity determination when samples are diluted up to 20 mL.
The borosilicate glass construction provides excellent chemical resistance and thermal stability.
It meets ASTM D445 and ISO 3104 testing standards for laboratory compliance.
The compact geometry fits standard constant-temperature viscosity baths.
