The principle of operation of this Viscometer is the same as all other rotational viscometers: a spindle (cylinder or disk) is submerged in the sample to be tested, measuring the force applied to overcome the resistance against rotation or flow. A spring is connected between

The Cannon-Manning Semi-Micro (page 8) is a U-tube viscometer that has been modified to measure the kinematic viscosity of samples as small as 1.0 mL. The Cannon-Ubbelohde Semi-Micro viscometer (page 6) is a modification of the standard size Cannon-Ubbelohde viscometer requiring a sample volume of only one milliliter.
