Cannon 9722-G68 Ubbelohde 300 Semi-Micro Uncalibrated

The Cannon 9722-G68 Ubbelohde 300 Semi-Micro Uncalibrated is a high-precision suspended-level viscometer designed for measuring the kinematic viscosity of transparent Newtonian liquids using small sample volumes. This instrument complies with ASTM D445 and ISO 3104 standards. Therefore, it ensures accurate, consistent, and internationally recognized viscosity measurements.

Product Features

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

Moreover, the suspended-level configuration maintains a constant hydrostatic head throughout the test. Consequently, it provides stable flow conditions and reliable results without the need for kinetic energy corrections. This unit is supplied as an uncalibrated viscometer, offering flexibility for laboratories that perform internal calibration. However, a calibrated version is available under model 9722-H68.

Specifications

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

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, academic research centers, and quality control laboratories. It is particularly suitable for intrinsic viscosity determination, polymer characterization, specialty chemical analysis, and other transparent Newtonian liquid testing. In addition, it supports laboratories that require precise measurements while minimizing sample consumption.
