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.
