The Cannon-Ubbelohde Semi-Micro Viscometer measures kinematic viscosity of small samples of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Minimum sample volume is ~1 mL (sizes 400 through 600 may require additional sample). Initial sample can be diluted as much as 20 mL for intrinsic viscosity determinations. Minimum bath depth is 240 mm (9.5 in). This is a calibrated viscometer which include a certificate of calibration and instruction sheet. Uncalibrated viscometers are also available.
