CANNON 9721-K68 Ubbelohde 300 Calibrated

The CANNON 9721-K68 Ubbelohde 300 Calibrated Viscometer is a precision suspended-level viscometer designed for accurate measurement of kinematic viscosity in transparent Newtonian liquids. This instrument complies with ASTM D445 and ISO 3104, ensuring standardized and reproducible viscosity testing in laboratory and industrial environments. Therefore, it is suitable for applications that require reliable performance across a wide temperature range.

Product Features

First, the Ubbelohde suspended-level design maintains a constant hydrostatic head during measurement. As a result, no kinetic energy correction is required within the broad viscosity range of 0.5 to 100,000 centistokes. In addition, the viscometer performs effectively at temperatures above 93 °C (200 °F) and below −18 °C (0 °F). Consequently, it is ideal for demanding testing conditions.

Moreover, this model is calibrated at 40 °C and supplied with a certificate of calibration and an instruction sheet. The viscometer constant remains the same at all temperatures, which ensures consistent and stable accuracy. Furthermore, its specifications conform to ASTM D446 and ISO 3105, providing traceable and internationally recognized testing standards.

Specifications

The approximate viscometer constant is 0.25 cSt/s. Therefore, it measures viscosity within a range of 50 to 250 cSt, corresponding to flow times between 200 and 1000 seconds. The minimum required sample volume is 11 mL. Additionally, a minimum bath depth of 254 mm (10 inches) is required, and the viscometer must be submerged to 220 mm (8.5 inches) during operation to ensure precise measurement.

Please note that the holder is sold separately. Compatible holder models include 9726-M70, 9726-M73, and 9726-M76.

Applications

This viscometer is widely used in research laboratories, quality control departments, and industrial testing facilities. It is particularly suitable for evaluating jet fuels, hydraulic lubricants, specialty oils, and other transparent Newtonian liquids. In addition, it supports viscosity testing at both elevated and low temperatures, making it ideal for petrochemical, aerospace, chemical, and energy industries.
