  • Five crystallization vessels to analyze up to 5 samples with no supervision required.
  • Analysis time of 6 hours per sample under standard conditions.
  • Fully automated process with no solvent handling, including a final cleaning of the lines and vessels.
  • No manpower and no solvents handling along the whole process.
  • Low solvent consumption.
  • Infrared Detector IR4 incorporated, with the possibility of adding a composition sensor for methyls or carbonyls measurement.
  • Virtual Instrumentation software with whole control of the instrument hardware and process.
  • Possibility of calibrating the instrument to obtain the CCD curve in comonomer content units.
  • Possibility of subambient capability (down to -20ºC) for low crystallinity samples.
  • Possibility of remote control connection to allow a fast diagnosis.
  • Possibility of adding a Viscometer detector.
  • Easily convertible to a CRYSTAF-TREF combined instrument.
