IV Tester

The IV Tester is to determine the intrinsic viscosity also called solvent viscosity or intrinsic viscosity. No chemical solvents are used in the determination. This method is used in particular for quality control of polyester (PET) or polyamide (PA).

Dermination of Intrinsic Viscosity
  • User friendly operation and display of measurements results via the integrated touchscreen
  • User friendly process to determine correlation factors
Optional Units
  • Manual die plug (special heated version for high temperatures available); Automatic melt cutting unit
  • Nitrogen purge for hydroscopic materials
  • Alternative steel grades for barrel and piston with higher corrosion or abrasion resistance
  • Data protection of parameters and results via uninterruptible power supply
  • Only mi2.2: Mechanism for pre-compressing and ejection with a higher weight

GÖTTFERT indexers come with different options. Furthermore, we also provides add-ons, which are extending the functionality of the device. The following add-ons are available:

  • Moisture measurement instrument
