Product Description

FRACTION FINDER | Real-Time Molecule Monitoring System for Wiped Film Evaporation

The FRACTION FINDER ensures precision and repeatability for wiped film evaporation, which translates to purer, more consistent distillate products.

The traditional method of real-time wiped film evaporation analysis is using temperature, wiper speed, and color changes to determine fraction changes. While this can and has worked well, the FRACTION FINDER can provide real-time parameter feedback so that you can fully dial-in your process.

Fraction Finder Applications

  • Short-Path Distillation: Detect fraction changes between “Heads”, “Main Body”, and “Tails”
  • Wiped-Film Evaporation: Tune process parameters, such as temperature and wiper speed
  • Ethanol Extraction: Know when the extraction process is over

In-Line Distillation Analysis

  • UV fluorescence sensor that attaches directly on the glassware apparatus, or using an adapter, or sight glass
  • Real-time sensor readings which transmit to a digital readout
  • Graphical display for instant determination of fractions

Intuitive Molecular Tracking

  • Identify transitions between distillation fractions, also known as “Heads”, “Main Bodies”, and “Tails”
  • Tune parameters, such as wiper speed and temperature, to ensure the best separation possible.
  • Set Molecule indicators and “Custom” wavelength ranges to track fluorescent signals for molecules of interest

Revolutionary Software Analytics

  • User-friendly touch-screen allows for overlaying and zooming in on wavelength fluorescence
  • Record, export, and review process data in a CSV file after the process
  • Update software with easily downloadable software with releases every few months
