See your process 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 processing as they are processing it. Through innovative in-line analytics, the FRACTION FINDER can detect presence and relative purity of botanical molecules. This can help processing facilities 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 material during the process is valuable insight. This information can be used to improve the process and ensure the highest possible output purity. Experienced technicians and managers can use this system to standardize their process 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 botanical 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.

Every kit contains: 

  • Fraction Finder Display
  • Fraction Finder Sensor (size 29 or 34)
  • Power Supply
  • Sensor Cable
  • Light-Blocking tape
  • Mounting Bracket Screw
  • User Manual and Quick Start Guide
  • 1-Year Warranty Card

Frequently Asked Questions

Which fractions can the Fraction Finder detect?

Currently, the Fraction Finder can detect Delta-9, degraded Cannabinoids, CBDA, and Chlorophyll. During short-path distillation, it can distinguish what is colloquially known as “Heads”, “Main Bodies”, and “Tails”.

Can the Fraction Finder be used to produce compliant Hemp distillate?

The Fraction Finder can detect a wide range of concentrations of fractions, which can help you to produce a cleaner cut of CBD distillate; however, it is not currently advised to use it as your only detection method for meeting federal requirements for Hemp. Currently, confirmation of low concentrations is best done via HPLC.

Does the Fraction Finder work the same as an HPLC?

Both systems use spectroscopic analysis to identify chemicals. However, the type of spectroscopy that detection method and wavelength regime are different.

  • HPLCs utilize light in the deep UV and typically uses a spectroscopic measurement called absorption. HPLC is highly analytical and accurate, but with the wavelength regime, it could never detect distillate through SPD glassware.
  • The Fraction Finder operates in the near-UV, using a spectroscopic measurement called fluorescence.

What units of measure does the Fraction Finder display use? 

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

Can the Fraction Finder sensor fit on size 24 glass?

If you have size 24 glass, order our 24/40 adapter. This will adapt to your glass and allow the Fraction Finder (size 29 sensor) to fit.

What heat can the Fraction Finder sensor handle?

The Fraction Finder sensor can handle around 100-120 degrees Fahrenheit. If you plan to meet or exceed these limits, we recommend that you order our Hot Tech Adapter. Contact Sales if you would like assistance with this.

Can you use the Fraction Finder on a Wiped Film Evaporator unit?

Yes, access our white paper on this page. If you have a VTA or similar setup, please order our WFE Jar Bundle; this will place the Fraction Finder post-gear pump and prior to collection point. If you have a Pure Path or similar setup, please order our Pure Path Rodaviss Adapter.

Can you use the Fraction Finder on an Extraction unit?

Currently, the Fraction Finder can be used for CO2 extraction, as long as the discharge is at atmospheric pressure. If this is the case, any of our adapters, such as the Jar Bundle, can analyze the discharged oil at collection point.

Do you offer any sight glasses that the Fraction Finder sensor can fit on?

Yes, we offer two 1.5″ Sanitary flange sight glass options in two sizes: size 29 and size 34.

Can the Fraction Finder integrate to my PLC?

No, it can not integrate into larger systems. However, the Fraction Finder has a Record feature and a Transfer feature. The Record feature will record and store run data. This feature is located on the bottom-right corner of the display. The Transfer feature will upload recorded run data (CSV) to a USB drive. (There is a port at the bottom of the display where a USB drive can be plugged in.) This feature is located on the bottom-left corner of the display.

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
