cbd isolate made with short path distillation

One such production advantage is something called “continuous feed” which is great for making large quantities of product for longer periods of time with greater consistency.

Let’s take a look at how the short path wiped film distillation process works.

The Short Path Distillation Process

But how much does a short path distillation system cost?

Flavor and “experience” are obviously more consumer-centered advantages, but for producers, there are many more that come with employing either a short path distillation process or short path wiped film distillation process.

It’s interaction with the endocannabinoid system means that CBG may assist in a whole host of disorders:

CBGA is the first cannabinoid to form in the trichomes of a hemp or cannabis plant. Certain enzymes, determined by the genetic makeup of the plant, break CBGA down into the three more well-known ‘major’ cannabinoids as the plant matures:

If CBG is the ‘Mother of all Cannabinoids’, it’s “children” are CBD, THC, and all of the other minor cannabinoids. Like all familial relationships, the parents and children behave in unique ways. CBG functions in a different way than CBD and may, in fact, be more powerful in its effects on the body.

6. The Challenge to Producers: Growing & Producing CBG is Costly

You may have heard CBG referred to as “The Mother of all Cannabinoids”. CBG is the non-acidic form of cannabigerolic acid (CBGA), the foundational compound or precursor from which all other cannabinoids (THC, CBD, etc.) are developed.

Extracting CBG efficiently begins while the plant is still growing. Because CBGA is the first cannabinoid to show up in young hemp or cannabis plants, there is a very slim window of opportunity to harvest the plants and ensure a financially viable yield.

Just like CBD and other major and minor cannabinoids, CBG helps to support your endocannabinoid system, which in turn supports a healthy state of balance in our bodies. That’s why CBG may be useful for so many different conditions.

Early studies indicate that CBG may be a beneficial treatment for a whole host of physical conditions. Although these early studies are certainly promising the science in this area is still very new and should be taken with a grain of salt.

The current thinking is that the oil is even more therapeutic when all the compounds are included; the whole plant has so many beneficial compounds, that together, they offer the greatest benefit.

A very specific heat and time ratio is critical, not only to convert THCa to THC, but also to prevent the THC from changing to a different compound. That’s why Apeks Supercritical has engineered thermally sensitive CO2 cannabis extraction systems using lower, plant-friendly temperatures for cold separation processing. Cold separation protects plant oils by never exposing them to temperature higher than the extraction temperatures, thereby protecting the volatile oils and terpenes, as well as retaining more THCa. Depending on the end products, processors may use the oils containing THCa (which offers its own therapeutic benefits) or convert it to THC.

STEP TWO: Remove the alcohol. This is done by gently warming the oil extract using a rotary evaporating machine. Alcohol’s boiling point is different from the oil’s, so it simply evaporates out of the oil. The alcohol is recovered and can be reused in the future.


To learn more about cold separation, watch this short video:

As described above, the conversion of THCa to THC requires heat. This is a chemical process called decarboxylation. The best way to get the highest yield through CO2 cannabis extraction is to decarboxylate it first. Typically, processors use ovens for this task. Once decarboxylated and dried, the material is ground up into a coffee-ground consistency. Watch a video of this process here:

With the proper products and training, processors can extract specific compounds like THC. Understanding boiling points of each compound is critical. Extraction processes takes time, money, and dedication but is well worth it! And with an Apeks Supercritical system utilizing cold separation to preserve the terpenes and other compounds, you can join other customers producing award-winning cannabis oils!

Separating the individual compounds of the cannabis oil extract is a labor intensive and specialized process known as short path distillation, or fractional distillation. Each compound of the cannabis oil boils at a different temperature, so when the oil is heated, the compounds are siphoned off as they reach their particular boiling point. The whole process requires specialized equipment and takes some time, so it’s not for the faint of heart! Distilling the individual compounds creates “isolates” – oil containing one compound for medicines targeting specific ailments. There is also a strong case for maintaining all of the compounds in the oil (see the entourage effect described below).
