Cannon-Ubbelohde Four-bulb Shear Dilution Viscometers
Five-Fold Dilution Type
For measurement of intrinsic viscosities extrapolated to zero shear rates. Provide five-fold range of shear rates. Design gives extra mechanical strength. Negligible kinetic energy correction.
Provided with Cannon’s ISO/IEC 17025 certificate of calibration and instruction sheet.
- Minimum sample volume 20 mL. Require liquid bath depth of 280 mm (11 inches)
- Holder sold separately. Refer to Catalog No. 9726-M70, M73, and M76

Ten-Fold Dilution Type
Similar to 9723-M50 series, but provide ten-fold range of shear rates.
Provided with Cannon’s ISO/IEC 17025 certificate of calibration and instruction sheet.
- Minimum sample volume 20 mL. Require liquid bath depth of 430 mm (17 inches)
