A guide to cannabis extraction equipment and machines.

Before any CBD oil, THC tincture, weed butter, or hemp concentrate can be purchased, it must first be extracted. This is the job of cannabis extraction equipment, the machines that extract the coveted cannabis compounds from the plant's matrix (the process is explored in detail here).

Just like any other piece of equipment, when considering extraction machines, the question inevitably arises: which machine is the most cost-effective?

Some are industrial grade, some are kettle-sized. Some use carbon dioxide as a solvent, others utilize alcohol. All have their pros and cons, which can be listed in a nice, handy guide to cannabis extraction equipment and machines. A guide just like this one.

Carbon Dioxide Cannabis Extraction

Carbon dioxide may not be the cheapest solvent, but the benefits are worth it. In these machines, high heat and pressure turn the gas supercritical, allowing it to be extracted in higher yields than many other solvent methods.

BOSS CO2 extraction system

Automation at all stages has improved the extraction process, especially in terms of repeatability and accuracy.Quadron Cannatech has focused on developing automated extraction systems specifically for the cannabis industry. Its BOSS CO2 extraction system incorporates automated controls that eliminate the need for manual valves and is designed to minimize loading and unloading times to increase production capacity. The company claims that by streamlining the process, its setup can process 20 pounds of cannabis material in four hours and run continuously without supervision, allowing for a total of six runs per day.

In all extraction methods, yield is always a key factor in improvement. For example, Supercritical Fluid Technology's supercritical CO2 extraction system, CannabisSFE, is capable of being run at both subcritical (terpenoids) and supercritical (cannabinoids) levels with a simple setup adjustment. Flexibility and scalability in throughput are always desirable attributes, especially in the fast-paced cannabis industry, where companies grow rapidly and requirements can change overnight.
Hi-Flo FX2 20L 5K

The Hi-Flo™ High Performance Series is known for its powerful processing capabilities, and one of the newest products in the series, the FX2 20L 5K, is no exception. Capable of handling up to 107 pounds of biomass per day, the extractor delivers up to 5,000 psi and fast switching for maximum extraction time.
Apeks Supercritical CO2 System

The most industrial extraction products should have intimidating names, and Force is certainly no exception. the Apeks supercritical system can handle up to 200 pounds of giant plant dry matter per day, and it's optimized to handle the largest workloads in the industry. It's for the professionals.
Super C Extractor

Compared to the industrial giants, OCO Labs' SuperC extractor looks like a toy. But don't be fooled by its size; for the right buyer, this small extractor is all-in-one. capable of handling 1oz at 4500psi by itself, the SuperC's capabilities can also be expanded with purchased add-ons, such as OCO Labs' rack specs.
Cannabis Alcohol Extractor

Along with carbon dioxide, alcohol is one of the most commonly used solvents for cannabis extraction. An inexpensive source, ethanol absorbs valuable compounds and then separates them through evaporation. But this inexpensive solution is not without its challenges. Ethanol is highly flammable, and any change in temperature can dramatically alter the final product. Fortunately, these machines come with instructions.

Internationally, Rotovap

More of a home chemistry set than an industrial extractor, Across International's Rotovap may be a perfect choice for the savvy buyer. In addition, due to its smaller size, the Rotovap offers greater control over the evaporation of liquid phase materials. Of course, any drawbacks come from the stripped-down design of the extractor. For example, any cooling system must be purchased separately.
Genius ASAHI Rotary Evaporator

Like Across International's Rotovap, the Genius ASAHI Rotoray Evaporator's solvent of choice, alcohol, helps keep it economical. Two cold chambers help keep chlorophyll trapped in the plant matter, giving the final product a lighter color and richer flavor.

Source Turbo

The Source Turbo is an extractor designed for the on-the-go cannabis connoisseur and can be operated remotely via a mobile app. No day is too crowded for this extractor. As an added feature, the Turbo is also equipped with adjustments for altitude, so it runs at peak performance whether you're on a mountain or a beach.

Part of the development of any form of equipment comes from the introduction of new methods. For example, ESCET has developed a method to extract cannabis with low-proof alcohols such as bourbon or vodka plus vegetable oils and water. The company claims that the method makes the extraction of marijuana much easier.
