ABSTRACT:
An improved differential pressure capillary viscometer in which a sample of solute in solution with a solvent is introduced into a stream of flowing solvent. The sample passes sequentially into first and second capillary tubes in which pressure differences are measured as a function of time. The pressure differences can be related to the viscosity of the sample.
