CANNON-Ubbelohde Four-Bulb Shear Dilution Viscometer
The Cannon Four-Bulb Shear Dilution Viscometer measures intrinsic viscosities extrapolated to zero shear rate with negligible kinetic energy correction. Minimum sample volume is 20 mL. Minimum bath depth is 280 mm (11 in) for 5-fold dilution viscometers and 430 mm (17 in) for 10-fold dilution type. Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet. Holders are sold separately.
