Cannon-Ubbelohde Four-Bulb Shear Dilution Viscometers

Five-fold dilution type

Calibrated CUSDC-11 (9723-M50) Series

For measurement of intrinsic viscosities extrapolated to zero shear rate. Provide five-fold range of shear rates. Design gives extra mechanical strength. Negligible kinetic energy correction. Read more about the significance of expanded uncertainty.

Provided with certificate of calibration and instruction sheet.

Uncalibrated CUSDU-11 (9723-L50) Series

Similar to 9721-M50 series, but uncalibrated.

  • Minimum sample volume 20 mL. Require liquid bath depth of 280 mm (11 inches).


Ten-fold dilution type

Calibrated CUSDC-17 (9723-R50) Series

Similar to 9723-M50 series, but provide ten-fold range of shear rates.

Uncalibrated CUSDU-17 (9723-N50) Series

Similar to 9721-M50 series, but uncalibrated.

  • Minimum sample volume 20 mL. Require liquid bath depth of 430 mm (17 inches). The CT-518 bath is recommended.



  • Holder is not supplied. For holders, see 9726-M70, 9726-M73, 9726-M76.
  • Viscometers with special constants are available by special order at additional cost.

Viscometer Accessories

Still need help choosing a viscometer? There are many reasons why one viscometer type is more appropriate or better suited than another. Because of these many reasons, we recommend you speak with one of our experienced staff members to assist you. You can however, use our viscometer selector to help point you in the right direction. The viscometer selector requires a target viscosity as input and outputs a list of viscometer types and sizes that are capable of measuring your target fluid.
