The FRACTION FINDER is the first and only in-line molecular sensor for fractional distillation. Its purpose is to assist laboratory managers, technicians, and consultants to optimize their processes. This system will help improve the quality, consistency, and value of distillate products.


Features & Details
  • Molecule Indicators – Detect and monitor key molecules in real-time (Delta-9 THC, THCa, CBD, CBDa, Degradates, Chlorophyll, Lipids, or Custom)
  • Intensity Values – Use standard digits to track molecule intensity values
  • Auto Highlighting – Simply check any given molecule’s checkbox and the screen will automatically identify and highlight the region that the molecule fluoresces at
  • Record and Review – Start and stop recording run data with the touch of a button for easy CSV review
  • Software Updates – Upgrade to free, feature-rich software releases easily from the field (currently V1.2.3)
  • Seamless Integration – Install directly onto distillation glassware (short path condenser, wiped film flask, or select an Arometrix adapter)
  • Technical Support – Support via phone call, SMS text message, and email
  • Bonuses – Made in the USA | 30-day money back guarantee | Arometrix Academy

Lack of Objectivity During Short Path Distillation

During distillation, it can be very challenging to monitor fraction changes and to determine the precise time to change fraction flasks. Before the FRACTION FINDER, the traditional method of ‘fraction finding’ relied fully on experience, eyesight, color changes, or lab results. However, these methods are unscalable, inconsistent, and can delay time-to-market.

Your Best Friend During Short Path Distillation

Through innovative in-line analytics, this system provides scientific, instantaneous graphing of key molecules relevant to distillation. Tracking these allows operators to see when the first fraction (aka Heads) begins/ends, when the second fraction (aka Main Body) begins/ends, and when the final fraction (aka Tails) begins. Knowing exactly when each fraction starts helps you to determine optimal flask transfers for precise and repeatable separation of fractions.

Furthermore, with this base unit, you have potential to integrate this into other processes, such as wiped film evaporation.

It’s Time to Fully Dial-in Your Wiped Film Distillation

This unit can also integrate to most wiped or thin film distillation units. Its real-time readings can indicate when desirables (i.e. cannabinoids) are being rejected or when undesirables (i.e. degrades, chlorophyll, etc.) are being collected. Based on this parameter feedback, the operator can fine-tune other controls, such as temperature or wiper speed, in order to minimize these pain points and ensure the most efficient separation possible.

In-Situ Fluorescence Spectroscopy

The FRACTION FINDER technology utilizes a principle known as fluorometry, a spectroscopic method of measuring molecules based on how they interact with light. The system primarily consists of the following:

  • Optical Sensor: Think of this as the “eyes” of the system. It operates in the near-UV fluorescence regime. The sensor wraps around a glass tube then connects and transmits to the pole-mounted display.
  • Touch-Screen Graphical Display: Think of this as both the “brains” and “face” of the system, as this interprets the signal and displays wavelength information.

Can you explain each of the adapters and their differences?

Most standard short path distillation brands have size 24, 29, or 34 glass condensers. For example, Summit Research, Lab Society, Across International, Beaker & Wrench, Best Value Vacs, etc. In most cases, you can directly install the sensor without an adapter. For other equipment, use a glass adapter to install the sensor.

How much heat can the Fraction Finder sensor handle?

The Fraction Finder sensor is specced to handle 100 degrees Fahrenheit. If you plan to exceed these limits, order one of our Hot Tech Adapters, which are easy to attach onto your unit.

Does this system work for wiped film evaporation or thin film distillation?

Yes! We have had great experience using the system for these processes to ensure separation parameters and optimization. See our Wiped/Thin Film Guide in our Resources section above, or at
