CANNON-UBBELOHDE FOUR-BULB SHEAR DILUTION VISCOMETERS

Five-fold dilution type
Calibrated CUSDC-11 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. Provided with certificate of calibration and instruction sheet.

 

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

Uncalibrated CUSDU-11 Series
Similar to 9723-M50 series, but uncalibrated.
