The Cannon-Manning Semi-Micro Extra Low Charge Viscometer measures kinematic viscosity of very small samples of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Minimum sample volume is ~0.5 mL (sizes 200 through 600 may require additional sample). Minimum bath depth is 230 mm (9 in). Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet. Holders are not available.
