Extraction methods that involve solvents are very popular and provide a quality product, but require professional equipment and knowledge to get right. Solventless methods are simple, natural but do not offer the same THC and cannabinoid percentages.
Some methods are superior and provide better taste, enhanced terpene retention and a pure product. Dry-sieve extraction typically involves taking dried cannabis plants and beating or shaking them against a mesh screen so that the trichome crystals fall off and can be collected.
Water extraction, also known as water hash or bubble hash is made by adding cannabis plants to a set of sieve-like bags submerged in freezing cold water and stirred.
The cold and stirring causes the trichomes to fall off the plant and pass through a progressively tighter series of collection screens. The result is a kief or hashish that can be dabbed or smoked and provides THC levels from 50 to 70 percent. Rosin is a cannabis concentrate that has a buttery or shatter-like consistency and is produced without using additives or solvents to extract the trichomes from the plant material. Instead, heat and pressure are used to extract the trichome rich resin that contains the beneficial ingredients of the cannabis plant.
Referred to as an ISO Wash, this extraction method involves taking dried cannabis flower and soaking it briefly in isopropyl alcohol. Once soaking, the mixture of ISO and flower is shaken gently and then strained into a separate dish. The isopropyl alcohol works to strip the trichomes from the plant material into the solvent. The concentrated liquid then has any remaining solvent evaporated in a vacuum oven at under degree Fahrenheit until a potent THC rich oil remains. ISO wash extract is typically filled with cannabinoids but also contains some chlorophyll, waxes and plant alkaloids.
The longer the soak, the more plant material will also be extracted, an undesirable side effect of this extraction method. Butane extraction has been made famous in the food and perfume industries but has since been repurposed for cannabis extraction due to its powerful potency and excellent terpene retention.
To perform a BHO extraction, a vessel or column is filled with cannabis, and a filter attached at one end. Cans of butane are sprayed through the cannabis to extract the cannabinoids, and the cannabinoid-rich butane is collected in another vessel. The solvent and cannabinoid mix is then left to evaporate or is purged in a vacuum oven. BHO extraction can be very dangerous if not done correctly as the butane gas being used is extremely flammable.
A vacuum oven works to purge the solvent residue from the oil and leaves behind a golden coloured oil that typically measures around 80 percent THC. This method is popular for producing many types of shatter, waxes, crumbles, and oils. Another famous extraction method, Supercritical CO2 extraction is a great way to get all those amazing cannabinoids separated from the cannabis plant material.
It is also the safest non-toxic and reusable, environmentally friendly solvent extraction method. Better yet, for all the health-conscious cannabis users out there, no trace amounts of toxins are left behind in the finished product. Supercritical CO2 is already being used as a safe industrial solvent in many industries including coffee, tea, fruit extracts, vanilla, omega-3 oils, perfumes, hop-oil for beer and lots more.
The same CO2 is nontoxic and is used in soft drink cans to provide fizz. This extraction process also does not contribute to atmospheric carbon emission increases. To begin extracting, supercritical CO2 is heated, which raises the pressure of the liquid CO2 that is then passed through the cannabis buds to extract the valuable cannabinoids.
Then the liquid CO2, now full of extracted cannabinoids, passes through a separator that breaks it down into constituent parts. Trichomes and terpenes are collected, while the supercritical CO2 gas is moved into a condenser to liquefy again before being recycled back to a storage tank. Then the collected extract is left out at room temperature so the remaining CO2 can evaporate into the atmosphere.
CO2 extraction does require a finely tuned piece of equipment but is very popular in the industry thanks to being both safe and highly efficient at creating the highest quality cannabis extracts. Supercritical CO2 extraction enables only selected compounds to be extracted with some small adjustments to the equipment.
The shelf life of the extract is also prolonged due to CO2 acting as a sanitizing agent. This method of extraction is great for making oil, shatter, budder or wax, depending on how the temperature, pressure, flow rate and solvent-to-feed ratio are tuned. Your preference will largely depend on what elements of an extract are most important to you. Cannabis extracts are a great alternative to dried flower because these concentrates can offer amazing flavourful taste and a clear high in an easy to use format.
The dry ice extraction method is another method of CBD extraction that can be performed at home although it takes a bit more time and effort than its olive oil equivalent. Put on your gloves and eye protection, chop up the cannabis plant into small pieces and place it in the bucket. Cover the plant with the dry ice and leave it for 3 minutes; it is best only to fill the bucket halfway; this process causes the freezing of the trichome resins.
Turn the bucket upside down on the Plexiglas and shake as much resin through the mesh bag as possible. Scrap the hash off the Plexiglas with your scraper and place it into one of the jars. Ethanol, low-grade alcohol, and butane are among the most common substances used in Solvent Extraction. Although ethanol extracts the full range of cannabinoids and terpenes from the plant which makes the end product safe for consumption, it also extracts chlorophyll which may lead to some unpleasant side effects.
Butane offers a stronger oil than ethanol, but it is more likely to contain solvents which could irritate the lungs. All you have to do is add the liquid whether it is butane, alcohol or ethanol to the plant material. The extraction liquid will strip away the cannabinoids and flavor from the plant material but will probably take some of the green colorings too.
Once you believe you have enough cannabinoids in liquid form, heat the liquid to evaporate it down to the CBD base oil. It is extremely important to understand the various CBD extraction methods as they have a major impact on the quality of the end product; not to mention your health.
The cost of CO2 supercritical extraction means it is not possible for Those who create their own CBD oils will tend to use dry ice or olive oil, which provide great purity, yield and are easy to do. There are also other extraction methods that we have not mentioned in this guide.

Then the solvent process will yield a higher quality of product. I would think ethyl ether would be even better, however way more volatile of a solvent. In any event, any reaction using ethyl ether should only be carried out by knowledgeable and qualified personnel.
If you thought butane was flammable, step aside cupcake, ether is extremely volatile. Also, keep in mind there is water in acetone too! Water is the most abundant solvent on earth, given time, it will break down anything. Why are you calling chlorophyll harmful? It actually enhances bioavilability and has other health benefits. Chlorophyll is very easy to remove from any extraction as well.
All you have to do is leave your extraction in the sun for an hour or two and let nature do it. Use fan leafs with lil clippings and used ISO I would do the same process but with high quality buds and high THC content leafs clippings and be a lot more delicate careful not too disturb it too much.
Pls help me understand this process. Cbd comes home with so many benefits. Capable of treating multiple sclerosis, a very bad disease. How do I achieve this?
In the US we need to be under 0. Most companies will use flash chromatography to remove THC from my experience. Cbd is surely a fighter to deal with any kind of sleeping problems. It is free of side effects that are common in painkillers so I am using it for insomnia regularly.
Far better than painkillers! Leave a Reply Cancel reply. Your email address will not be published. Remember me Lost your password?
