Cannon 9722-G74 Ubbelohde 400 Semi-Micro Uncalibrated

The Cannon 9722-G74 Ubbelohde 400 Semi-Micro Uncalibrated is a high-precision suspended-level semi-micro viscometer designed to measure the kinematic viscosity of transparent Newtonian liquids in accordance with ASTM D445 and ISO 3104. This instrument is ideal for laboratories that require accurate viscosity measurements while working with small sample volumes.

Product Features

The semi-micro Ubbelohde design enables testing with a minimum sample volume of approximately 1 mL. However, for sizes 400–600, a slightly larger sample volume may be required to ensure proper operation. This makes the instrument suitable for limited, costly, or research-grade samples.

Additionally, the initial sample may be diluted up to 20 mL for intrinsic viscosity determinations. Therefore, it is well suited for polymer solution studies and advanced material characterization. The suspended-level construction maintains a constant hydrostatic head, ensuring stable flow conditions and consistent measurement accuracy.

This unit is supplied as an uncalibrated viscometer, allowing laboratories to perform their own calibration procedures. For users requiring a certified calibration, the calibrated version is available under model 9722-H74.

Specifications

Minimum sample volume is approximately 1 mL, with larger volumes required for sizes 400–600. The sample can be diluted up to 20 mL for intrinsic viscosity testing. The minimum required bath depth is 240 mm (9.5 inches) to ensure proper immersion and temperature stability during measurement.

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 institutions, and quality control environments. It is particularly suitable for intrinsic viscosity determination, polymer analysis, specialty chemical testing, and other transparent Newtonian liquid measurements. Furthermore, it supports laboratories that need accurate viscosity results while minimizing sample consumption.
