Cannon 9722-G71 Ubbelohde 350 Semi-Micro Uncalibrated

The Cannon 9722-G71 Ubbelohde 350 Semi-Micro Uncalibrated is a precision suspended-level semi-micro viscometer developed for measuring the kinematic viscosity of transparent Newtonian liquids using minimal sample volumes. The instrument complies with ASTM D445 and ISO 3104, ensuring standardized and reproducible viscosity measurements for laboratory and research applications. Therefore, it is highly suitable for environments where both accuracy and sample efficiency are essential.

Product Features

First, the semi-micro Ubbelohde design allows viscosity testing with a minimum sample volume of approximately 1 mL. As a result, it is ideal for limited, expensive, or research-grade samples. In addition, the initial sample can be diluted up to 20 mL for intrinsic viscosity determinations, making it particularly suitable for polymer and solution analysis.

Moreover, the suspended-level configuration maintains a constant hydrostatic head during measurement. Consequently, it ensures stable and consistent flow conditions for reliable test results. This model is supplied as an uncalibrated viscometer, providing flexibility for laboratories that perform in-house calibration. However, a calibrated version is available under model 9722-H71.

Specifications

Minimum sample volume is approximately 1 mL. For intrinsic viscosity measurements, the sample may be diluted up to 20 mL. The required minimum bath depth is 240 mm (9.5 inches), ensuring proper immersion and temperature stability during testing.

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 polymer research laboratories, petrochemical testing facilities, chemical analysis labs, and quality control departments. It is particularly suitable for intrinsic viscosity determination, polymer characterization, specialty chemical testing, and other transparent Newtonian liquid measurements. In addition, it is ideal for laboratories that require precise viscosity testing while conserving sample volume.
