Viscostar – Viscometers


The ViscoStar® and microViscoStar™ on-line differential viscometers measure the intrinsic viscosity of polymers downstream of SEC. Differential viscometry is best combined with MALS and RI for analysis of polymer conformation and Mark-Houwink parameters.

On its own, the ViscoStar may be utilized with the Universal Calibration technique or Mark-Houwink parameters to assess polymer molar mass / molecular weight over a wide range.
