The FRACTION FINDER is the first and only in-line molecular sensor for botanical extraction and short path 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.

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 the proper distillation duration, and whether you were under-distilling or over-distilling. 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?

The range of prices is based on the adapter that you will use to install the sensor into your processing system. Hence, why on the product page, you must choose from a few different options.

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. Below are great resources:

How much heat can the Fraction Finder sensor handle?

The Fraction Finder sensor can handle around 120 degrees Fahrenheit. If you plan to exceed these limits, order one of our Hot Tech Adapters, which are easy to attach onto your unit.

I have a wiped film evaporator and can put the Fraction Finder on one or both lines. What should I do?

That is up to you and your process goals. It is only essential to operate with one. Our wiped film application note discusses this in much more detail.
