CANNON-Ubbelohde Dilution Viscometer
ASTM D445, ISO 3104
The Cannon-Ubbelohde Dilution Viscometer measures intrinsic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Minimum sample volume is 8 mL (can be diluted to 40 mL). Minimum bath depth is 305 mm (12 in). The CANNON CT-518 bath is recommended. (CT-500 and CT-600 baths are not deep enough.) Viscometer constant is the same at all temperatures. Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet. Holders are sold separately.
