Cannabis concentrates have exploded in popularity in the last few years. Solvent-based extracts are derived using a hydrocarbon. In contrast. As the popularity of cannabis concentrates increases, more and more Learn more about solventless and solvent-based concentrates as well. Several common forms of cannabis extraction rely on a solvent, such as alcohol. A cannabis tincture created using alcohol-based extraction.
cannabis extracts Solvent-based
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 production process is also more environmentally friendly, and depending on the extraction method used, there may be no toxic chemicals in use CO2 extraction.
The process of extraction also often kills microbial bacteria and excels at producing shatter, budder, wax, oil, and liquid for vaporizers or E-pens. One of the most widespread methods among professional laboratories and requiring a huge investment in scientific equipment, extracting with Carbon Dioxide results in the cleanest, most residual-free of all solvent extracts, significantly safer than BHO.
However, the disadvantage of CO2 oil is that many terpenes are often lost during extraction , meaning these extracts tend to have a nondescript, homogenous flavour regardless of the strains being processed. For this reason, a large proportion of the CO2 oil produced is used either in edible products and most commonly in tincture-type oils , where flavour is less of an issue.
Cannabis distillates and isolates are increasingly common products in the growing legal markets in the USA. A laboratory technique known as Short Path Distillation is employed to further purify and separate cannabis extracts, either solvent or solventless, cleaning them of any residual solvents, pesticides, waxes and lipids to create a high purity extract and one of the most expensive products on the market, due to the lengthy process involved in their production.
They have a colour ranging from almost clear to light gold to amber and can be smoked, dabbed, eaten or incorporated into cookery recipes. Most often though, distillate is re-combined with terpenes and used to fill vape pen cartridges. Time has shown that the quality of the end product depends on the quality of the material used, so for this reason more and more processors choose to use only the best extracts from organic grows in the preparation of their medicinal distillates.
While the initial distillation process separates the cannabinoids from the terpenes, waxes and lipids in the original extraction, Isolate is the result of further purification of these decarboxylated cannabinoids.
Yields, however are very low indeed with this last process. Thanks for providing this complete guide here through this post. These techniques of extracting the solvents are really effective and useful.
It is was very essential for everyone to know about the facts and proper knowledge related to this technique. Thanks for sharing informative post like this. I want some of that butter and hash have a cannabis medical card. I bought a syringe with pure CO 2 oil pineapple express. I bought it to add to my CBD tincture. What did I do wrong? Can you help me figure this out?
Hi Leah, thanks for your question. I would try adding a few drops of whatever oil or alcohol has been used, in the same ratio as the original tincture, which ought to allow the CO2 oil to dissolve. Let me start by explaining that marijuana concentrates are just that: Lucky for me, due to my geographic location in and around the Toronto—Montreal area I had access to good imported hash. Today, concentrates are separated into two distinct categories: Press kief into hash or use it as is.
For larger batches, commercial auto-tumblers such as the Pollen Master are available: Cold water extraction is done by placing ice, cold water, and cannabis into a holder lined with mesh bags of increasing grade and gently agitating the mix to knock the trichomes off to then be collected in the bag system. Once the good stuff has been extracted it must be dried to preserve flavour and potency and prevent mold.
Like dry sift screens, mesh bags can be made at home or bought commercially from Bubble Bag or other sources. But they are non-solvent concentrates and they easily rival solvent-based ones in strength and effect for dabbing.
Common solvents used in making concentrates are isopropyl alcohol, lab-grade naphtha , ether, and butane.

Over the past five years the cannabis world has been turned upside Solvent- based concentrates are a mix of oils, waxes, cannabinoids, and. Solvent-based and solventless marijuana concentrates are products that have been created from the cannabis plant and are much more potent. A cannabis extract is any oil-like substance that concentrates the chemical cannabis in on the back of the famous anti-pot campaign.
