Automatic Capillary Viscometer

The viscosity measuring station with the ViscoSystem AVS 470 is used to measure flow time of synthetic polymer solutions, through a capillary tube of a viscometer place in constant temperature immersion circulator. AVS unit memorizes times of flows and calculates average time of flow, the kinetic viscosity and other types of viscosities, like dynamic viscosity or intrinsic viscosity. The technique can be used to measure solution viscosities in the range of 0.35 to 30,000 centipoise for a solution density of 1 g/mL. The viscosity measurements are used to deduce intrinsic viscosities and molecular weights of the polymer and their degree of branching.
