ABSTRACT:
A viscometer for measuring the viscosity of volatile liquids or liquids that are easily contaminated in the air, is disclosed. The viscometer is of the capillary type and includes a U-shaped tube with a capillary adjacent the bight in one arm and a collector adjacent the bight in the other arm. In addition, the arm containing the capillary has two bulbs in series above the capillary and a stopcock adjacent the upper end. The other arm is equipped with a reservoir for a liquid sample to be tested, a branch passage adjacent the top and a plug valve for closing off the arm below the branch passage. The two arms are joined by a bypass above the reservoir and the bulbs. A stopcock is included in the bypass.
