The mother liquor still contains dissolved CBD. This solution can be reprocessed! One caveat is that the mother liquor will accumulate THC over time. This sets a practical limitation to the number of crystallization.

Without chromatography equipment, we can still make the CBD crystals, we can jump over the chromatography isolation step, just do the crystallization to get high purity CBD crystals. Turns out this is cost-effective method, widely used in making CBD crystals. Here we will introduce how to do it!

Make sure the jacketed vessel’s vent/condenser is connected to an appropriate chiller for pentane vapors. The boiling point of pentane is 36C. Even at lower temperatures, pentane will release many vapors. BE CAREFUL AND TAKE ALL PROPER PRECAUTIONS! Make sure the vessel condenser is cooled to -20C. Use a three to one ratio of CBD oil to pentane and set the machine to stir this mixture(some oils require slightly more or less pentane) in the jacketed vessel. Turn on stirring and turn on the heating bath and set to 45C. Wait until the solution reaches 45C and all the oil has dissolved.

CBD is one of the most popular cannabinoids that come from cannabis. CBD continues to grow in popularity and has seen applications ranging from the food industry to the medical field. When it is extracted and isolated without any other cannabinoids, we call it isolate. CBD crystals are one form of CBD isolate available to users. CBD isolate is the purest form of cannabidiol, composed of at least 99% CBD. Through a unique extraction and purification process, manufacturers remove all other plant extracts from hemp-sourced CBD oil. What remains? An incredibly pure, white powder that is tasteless and odorless. Basically, these crystals are pure cannabidiol without other cannabinoids or other compounds. This means that the CBD crystals don’t have any traces of terpenes, flavonoids, THC, or the other compounds that are usually present in your typical full-spectrum CBD products.

Quality CBD crystals begin with Quality CBD distillate. Always remember this. The starting material should be extracted CBD oil that has been decarbed, winterized and distilled. The CBD oil may need to go through several distillation passes before it’s considered pure enough to crystalize as a CBD isolate. It should be a very light yellow or completely clear in color once enough of the impurities are removed. CBD distillate should be clear. Cloudiness means there are contaminants like water, waxes and fats. If the oil is cloudy try winterizing again until the oil becomes clear.

Precipitation: Set the bath to 5C. Slow the stirring. As the solution cools it will become more viscous. Adjust the stirrer to keep the RPM above 120. CBD crystals will spontaneously form or crash out of the pentane solution. Keep reducing the temperature to at least -10 C. What temperatures you use and how they change over time can change the growth of the crystals.

Once precipitation stops, flush or physically remove The CBD crystals from the reactor. Vacuum filter the crystal/liquid slurry to remove the mother liquor from the CBD crystals. Rinse the crystals with ice-cold pentane to rinse impurities from the crystal surfaces. More rinses with pentane can improve poor color, but losses in total yield will occur. Keeping the CBD and materials cold during this step will help give you a better yield.

A glass nutsche filter vessel with stirring will be used to dissolve and crystallize the CBD. A heating/cooling bath is connected to the vessel jacket and will be used to control the temperature of the vessel. You’ll also need pentane, it has a low boiling point, so it’s easy for it to overheat and cause issues during the crystallization process. . Be careful! This can be dangerous stuff.

Most cannabis processors are not going to have access to industrial chromatography equipment to produce crystals, chromatography system is very expensive, you need very professional people to do the method development and run the system.

Technically, CBD crystals are classified as pure CBD isolate. Cannabidiol crystals are available in the solid, diamond-like form. In order to make CBD crystals, you will need special equipments. Chromatography, which is a method of isolating and purifying cannabinoids, is often used in the cannabis industry to separate THC and CBD from already extracted cannabis. Crystallisation is a key step in CBD isolation. After chromatography is used to refine CBD to very high levels, removing THC, terpenes and other impurities, the CBD is further purified and collected in solid form by crystallising it from the extract. This is typically done with strong solvents which help remove the THC which stays liquid.

Pentane and other volatiles can be very dangerous due to their low flash points. Don’t try this without consulting your safety officer and evaluating all of the possible safety concerns.

You may be familiar with extractions, and if you’re not feel free to check out this article here discussing the two main types to refresh your knowledge, either way, in order to form crystals you must start with a cannabinoid-rich cannabis extract.

Crystalline Isolate is an extremely pure form of cannabinoid that is extracted using CO2 or butane/propane. Available in both THC-A and CBD, crystalline can contain up to 99.97% THC or CBD depending on the application.

The only caveat to this is that you will not have the accompanying terpenes, and therefore will not experience the “entourage effect” that cannabis flower provides. However if you are intent on re-creating such an experience, you can reintroduce cannabis terpenes into your crystalline, or simply soak it within “terp sauce”.

So How Do They Make This Stuff?

The first step is to take your cannabis extract and mix it with acetic acid and hexane, the combination of chemicals will act as a solvent to separate the dissolved plant matter from the THC/CBD. After the mixture has had time to settle, it is put through a filter and then the remaining fluid is placed within a roto-vape where the acetic acid and hexane are evaporated off. The remaining mixture will be primarily Delta-9 THC-A or CBD-A.

In order to further purify the extract, chromatography is used in order to separate impure elements of the solution from the desired cannabinoids. Chromatography (sounds complicated but isn’t really) is a chemical process where different materials and mediums are used to separate different components within a solution based on its affinity to the different filter mediums and density (kind’ve like your standard water filter). In the instance of THC-A, chemists add Sephadex-LH20, dichloromethane and chloroform in order to further clarify the cannabis extract into majority cannabinoids and solvent devoid of any plant material.

The remaining solvent from the mixture needs to be evaporated, so it is placed within the roto-vape again, where it crystallizes. Afterwards, in order to make the crystals consumable, they go through a series of chemical washes, filtrations and roto-vaping.

Post chromatography, the crystals are dissolved in methanol and then filtered and then roto-vaped to remove the methanol. Afterward, pentane is used to remove the smallest bits of non-THC or non-CBD material and then roto-vaped for the last time. The results, white crystals testing at 99.97% cannabinoid.

Ideally, in order to maximize on time and resources, A-grade flower with a high THC-A or CBD count (depending on what you’re isolating) will be blasted with CO2 or butane/propane in order to extract the greatest yield of cannabinoids from the plant material. The crude oil that is extracted isn’t completely “clean” and will typically have a fair amount of waxes and lipids emulsified within the oil. Once the crude oil is winterized and the major waxes and lipids are filtered we would be left with cannabis extract that could be placed within a vape cartridge or dabbed on a rig. However, this oil will range from 65-90% THC or CBD and still exist within a viscous/fluid state. In order to solidify the cannabinoids out of the remaining non-cannabinoid material, we must take the cannabis extract add different solvents in different stages and run it through a number of different filtrations.

While it is certainly possible to draw out extracts that are extremely high in THC and CBD with CO2 and hydrocarbon extraction and distillation, but THC-A and CBD crystalline opens up different potentials for storage and consumption to the market. For instance, storage is much more convenient when using crystalline isolate, less messy when dabbing, and easier to incorporate into foods and topicals (presuming you have decarboxylated your crystals). Did I mention that it is also very pretty to look at?

For some this high-potency offering may seem excessive, but for many it is rather attractive. Medical marijuana patients are actively seeking the benefits of higher doses while veteran smoker may be looking for a new level of high. No matter the use, crystalline isolate is an exciting development within the chemistry of cannabis and the development of novel methods of consumption devoid of any harmful solvents and carcinogens.

Once all of the impurities and solvents are stripped away, you’re left with 99% pure CBD crystalline.

Anyone who wants to try CBD oil or other products may get cold feet after hearing about the presence of THC in hemp-derived products. But CBD isolate provides a way to enjoy the benefits of this cannabinoid without other unwanted plant parts.

While you might not know what to do with a pile of odorless CBD isolate powder at first, there are a number of different ways to consume CBD isolate. Here are some of the most common delivery routes:

While it’s true that hemp-derived CBD doesn’t have the same psychoactive effects as THC, that doesn’t mean it’s completely free of THC. According to federal law, hemp plants and hemp-derived products are legally permitted to contain up to 0.3% THC.

For topicals, mix the CBD isolate with moisturizing oils or lotions and apply it to the area of your skin you’d like to treat. You can also buy topicals that contain CBD isolate.

Topical.

When shopping for CBD isolate, it’s important to look for products from reputable companies that are lab-tested by a third party. This should ensure that your isolate doesn’t contain any THC, additional plant materials, or other impurities.

CBD is cannabidiol, a phytocannabinoid found in cannabis plants. CBD isolate is CBD that has been isolated from all other plant material through a process of extraction and refining. CBD isolate is available in crystal or powder form.

It’s incredibly easy to measure CBD isolate dosages, as there’s nothing else to account for aside from the pure CBD crystals.

It’s incredibly easy to measure CBD isolate dosages, as there’s nothing else to account for aside from the pure CBD. With other CBD-based products, such as broad-spectrum and full-spectrum CBD oil, the cannabinoid is mixed with other cannabinoids, making it more difficult at times to quantify the exact amount of CBD that is being consumed.

It depends on who you ask and why they are using CBD. Isolate is best for avoiding any possible trace of THC while full-spectrum may confer the additional benefits of other cannabinoids and terpenes via the entourage effect.

CBD crystalline can be measured and put into capsules or pills, allowing you to ingest an accurate dose. You can also mix CBD isolate with a variety of ingredients to create CBD-infused food and drinks. However, because CBD is not absorbed very well by the gastrointestinal tract, it has a low oral bioavailability. In order to increase bioavailability, CBD isolate can be added to carrier oils, such as MCT oil, to increase its chances of permeating the gastrointestinal system and reaching the bloodstream.

CBD isolate is an option for those who want to experience the potential therapeutic effects of CBD without even the smallest trace of THC.

Depending on the process, the resulting product is either large CBD crystals or a fine white powder that resembles confectioner’s sugar. While there may be a slight residual cherry flavor, neither form of CBD isolate should contain a distinct odor or taste. But don’t be fooled by its plain appearance — there are actually a number of reasons to get excited about CBD isolate and all that it has to offer.

As we’ll discuss in detail below under How to Use CBD Isolates, another clear-cut advantage is the many inventive ways CBD isolate can be prepared for use. Whether it’s administered sublingually or mixed with food and drinks, this crystalline powdered CBD works well in a variety of consumption methods.

Benefits of CBD isolate.

It might not seem as appealing as the well-packaged CBD oil, topicals, or pre-rolls, but CBD crystalline is surprisingly versatile when it comes to consumption, and this pure powder has a number of advantages over other conventional forms of CBD.

Following the mainstream emergence of cannabidiol (CBD) products, there’s a compelling option out there for those who want to experience the potential therapeutic effects of CBD without even the smallest trace of THC. It may not receive the same amount of hype as CBD lattes, infused cookies, or other CBD products, but CBD isolate is actually one of the most distinct and versatile forms of CBD on the market.

CBD isolate is a crystalline solid or powder that contains 99% pure CBD. A traditional extraction process removes all the active compounds from the cannabis plant. Then, a refining process that strips away all other phytocannabinoids, including THC, and any plant matter. What remains is the CBD chemical compound in its purest form.

Apply the CBD powder directly under your tongue and hold it there for about 60 seconds. With this method, the CBD is absorbed by the mucous membranes and delivered directly to the bloodstream, bypassing the digestive system to provide more immediate and effective relief.

CBD isolate can be mixed with terpenes to create homemade CBD concentrates that can be vaped or dabbed. The isolate can also be made into crystal slabs that can be dabbed using a traditional oil rig.

There are various processes used to produce CBD isolate from industrial hemp extracts, such as supercritical carbon dioxide (CO2) or ethanol-based extractions. The same extraction methods can also be used as a starting point for the production of THC isolate as well, but typically with marijuana plants instead of industrial hemp. To create an isolate, a number of components are removed from the plant, including other cannabinoids, terpenes, and flavonoids, as well as fats, lipids, and other compounds. After that, the CBD compound is separated from the rest of the extraction through a series of chemical washing and separation processes.

If someone is testing for CBD isolate, yes. But common drug tests look for THC and its metabolites. And part of the point of CBD isolate is that it doesn’t contain any THC, unlike full-spectrum CBD products, which are legally permitted to contain up to 0.3% THC. Generally, worries about CBD oil and drug testing are unwarranted but it’s even less of an issue with CBD isolate.

For starters, true CBD isolates consist of nothing but pure CBD, so there’s no need to worry about THC possibly entering your system and showing up on a potential drug test. Although it’s highly unlikely, trace amounts of THC found in hemp-derived CBD oil can theoretically cause a positive drug screening result.

While consuming CBD isolate might sound like a great approach, keep in mind that there is also a key disadvantage of isolating CBD from other cannabis compounds. Research has shown that the combination of cannabinoids and terpenes generates an entourage effect, a synergistic interaction that boosts the individual effects of each compound involved. Stripping away all the other cannabinoids prevents you from experiencing the potential benefits of the entourage effect.

However you choose. The section above on how to use CBD isolate contains several suggestions, including orally and topically.
