摘要
Flow characteristics of liquids esp. biological liquids are measured by determining the pressure drop across a capillary tube section. A fixed volume of liq. is drawn through in a constant time and the pressure drop is accurately monitored. An auxiliary liquid can be used if necessary. The sample liq. is drawn through by a piston type pump through the test section to control its temp. under rest conditions. It is then pump. This is followed by a high shear action to determine the viscosity in the non-Newtonian region. For use on biological liquids esp. blood. Because the system is programmed, the measurement is easy and different liquids can be checked without problem.
