  • Software Updates – Upgrade to software releases easily from the field

Lack of objectivity during fractional distillation

Botanical processors don’t know their product’s quality until after the distillation is over. This is because traditional molecular analyzers are hardware-hungry and can only be utilized after for sample testing after the process.

During the process, processors are forced to rely on subjective techniques, such as eyesight, experience, and guesswork, and indirect techniques like temperature. This lack of analytical tools during the processing leads to human error and “bad” batches. Now, you can forget the old ways of manually ‘finding fractions’. The FRACTION FINDER approach improves the quality, consistency, and value of processed botanicals.

Make smarter decisions based on data

Arometrix’s disruptive solution is the patented FRACTION FINDER. Processors refer to it while they are operating to view current process status and undertake corrective actions if needed. By using the Fraction Finder in tandem with existing laboratory & processing techniques, you’ll have a wealth of additional information on which to base decisions.

For example, the data will tell you when to change your collection flasks so that the different fractions are more optimally separated. The main fractions are “heads”, “bodies”, and “tails”. Knowing exactly when each fraction starts helps you to determine optimal flask transfers for precise and repeatable separation of fractions.

Additionally, this technology is great for rapidly training novice technicians on the process, or standardizing distillations across a large facility.

Applicable processes for this model includes small, benchtop, and industrial distillation process, including short path distillation, thin film distillation, and wiped film evaporation / distillation.

Powered by fluorescence spectroscopy

The FRACTION FINDER technology utilizes a principle known as fluorescence spectroscopy, a branch of science concerned with measuring molecules based on how they interact with light. The Fraction Finder uses a spectrum of wavelengths over time to determine the relative purity of oils flowing through a glass condenser or sight glass. This technique paves the way for precision and repeatability, which will yield a more consistent product over time.

Product Details

Included in this package:


What fractions can this detect?

The Fraction Finder can detect distillation fractions, colloquially known as the “Head” fraction, “Main Body” fraction, and “Tail” fraction.

How much heat can the Fraction Finder sensor handle?

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