Extensional Viscosity & Intrinsic Viscosity

Viscometers Used for Food & Beverages

Extensional viscosity (also known as elongational viscosity) is measured by exposing a sample to extensional deformation and extensional shearing. This application can be significant on various industrial processes including but not limited to: 

  • Fiber spinning
  • Paint rolling
  • Roll coating
  • Inkjet Printing
  • Spraying
  • Electrospinning
  • Enhanced oil recovery
  • Drag reduction
  • Food processing

Intrinsic viscosity is the value gathered when the viscosity increases as a result from adding an infinitesimal amount of solute to a solvent. Using intrinsic viscosity values, many of our customers estimate the hydrodynamic radius as well. To measure intrinsic viscosity values successfully, the viscometer used needs to be extremely accurate and precise. 

VROC® powered viscometers deliver accurate and reliable extensional as well as intrisic viscosity with

  • Less than 1 minute for a measurement
  • Don't need to clean in between miscible samples
  • High resolution to detect the slightest changes in viscosity
  • Smallest sample volumes - less mess and easy to measure
  • First principle or true viscosity
