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). Minimum bath depth for viscometers with the 10x range of shear rates is 430 mm (17 in). Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet. Holders are sold separately.
