See your short path distillation better than ever before with this in-line molecule monitoring system.

The FRACTION FINDER is the first-of-its kind, built to assist laboratory technicians, consultants, and managers see what is in the materials they are distilling as they are distilling it. Through innovative in-line analytics, the FRACTION FINDER can detect the presence and relative purity of botanical molecules during short path distillation. This can help distillers increase purity, repeatability, and traceability on every distillation pass. Now, you can forget the old ways of relying on manual, subjective, and indirect methods to monitor fractions. Instead, directly identify the contents with scientific fraction monitoring.


Knowing what is and isn’t in your oil during the distillation is valuable insight. This information can be used to improve the process and ensure the highest possible distillate purity. Experienced technicians and managers can use this system to standardize their short path distillation and to train new staff. Novice technicians can use it to learn, understand, and optimize.

How does it work? The FRACTION FINDER system uses a spectrum of wavelengths over time to determine the relative purity of botanical oils as they are flowing through a glass tube. It utilizes a technology known as fluorometry, a spectroscopic method of measuring molecules based on how they interact with light.

What is it? The world’s first and only in-line molecule monitoring system for short path distillation. The system consists of a sensor and a display.

  • SensorThink of this as the “eyes” of the system, as it contains an optical light pulse and detector. The sensor wraps around a glass tube then connects and transmits to the pole-mounted display.
  • Display: Think of this as both the “brains” and “face” of the system, as this interprets the signal through an advanced compute module, and displays optical information that is correlated to relative oil purity present in the flow.

Frequently Asked Questions

Which fractions can the Fraction Finder detect?

During short-path distillation, it can distinguish what is colloquially known as “Heads”, “Main Bodies”, and “Tails”. Click here for a list of molecules, such as Delta-9 and more.

What units of measure does the Fraction Finder digital readout use? 

The system uses Nanometers (nm) and Intensity (au).

What does “Like-New” sensor condition mean?

A “Like-New” sensor is a practically untouched sensor in perfect condition. A “Like-New” sensor was showcased or demonstrated at a trade show at some point, then brought back to our warehouse and quality tested. Please note that this option only refers to the sensor itself – not the whole unit. If you select this option, all other parts (digital display, cables, etc.) will still be brand new.

Can the Fraction Finder sensor fit on size 24 glass?

If you have size 24 glass, select that option before adding this to the cart or order our 24/40 adapter, which can fit a size 29 sensor. 

How much heat can the Fraction Finder sensor handle?

The Fraction Finder sensor can handle around 100 degrees Fahrenheit. If you plan to exceed these limits, order one of our Hot Tech Adapters.

Is the software upgradeable?

Yes. And it’s free to update! We release updates every few months. The Fraction Finder software is updatable from the field and accessible via
