Cannon-fenske Opaque Viscosity Tubes

Reverse-flow type, for measurement of kinematic viscosity of dark Newtonian liquids according to ASTM D 445 and ISO 3104. Permit measurements of liquids whose meniscus cannot be seen at the timing marks when using a Cannon-Fenske Routine type viscometer. Factory calibration certificate is supplied. Requires minimum sample volume of 12mL. Used to measure kinematic viscosity of...
