ABSTRACT:
An apparatus for determining the viscosity of fluids, particularly blood plasma, includes an outer housing including a front surface having a groove therein; a disposable capillary tube removably mounted in the groove and including at least one loop, each of the loops having two substantially horizontal branches including an upper branch and a lower branch for flowing the fluid under the influence of gravity through a predetermined path, and a device for measuring the rate of flow of the fluid along the path in one of the horizontal branches. Also disclosed is a flexible disposable capillary tube for the fluid viscosity measuring apparatus.
