Intrinsic Viscosity with Repeatable, Small Sample Viscometer m-VROC

A solute's contribution to the viscosity of a solution, or its intrinsic viscosity, is strongly affected by the strength of molecular interactions. As a result, intrinsic viscosity can help understand the molecular structure (i.e. Molecular Weight, Branching,...).

m-VROC™ offers several advantages over conventional viscometers including:

  • Smallest Sample Volume
  • Temperature Control: 4 - 70ºC
  • Superior Accuracy (2% of Reading) and Repeatability (0.5% of Reading)
  • No Air-Liquid Interface (No Evaporation or Contamination)
  • Wide Dynamic Range:

    • Viscosity: 0.2- 200,000 [cP]
    • Shear Rate: 0.5 - 1,400,000 [1/s]
