Product Description

FRACTION FINDER | Real-Time Molecule Monitoring System for Short-Path Distillation

The FRACTION FINDER ensures precision and repeatability for short path distillation, which translates to purer, more consistent distillate products.

The traditional method of botanical distillation has been using temperature, vacuum, flow, and color changes to determine fraction changes. The FRACTION FINDER provides a more direct and scientific method of doing this, acting as an additional tool for operators.

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
  • Real-time sensor readings which transmit to a digital readout
  • Graphical display for instant determination of fractions

Intuitive Molecular Tracking for Short Path Distillation 

  • Identify transitions between distillation fractions, also known as “Heads”, “Main Bodies”, and “Tails”
  • Track for the appearance of botanical fractions
  • 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
