One of the most significant aspects of making BHO concentrates is obtaining high-purity solvents. You can choose the type and grade of solvent based on your preferences and experience level, which is commonly 100 percent N-butane or 95 percent or higher.
The amount of butane you’ll require is determined by the amount of material you’ll be extracting as well as your storage constraints. The ratio of solvent to biomass is also affected by how the biomass is packed. Is the material loose or compactly packed? The efficacy of your solvent is influenced by the structure of your packed column.
Butane and propane have no odor or color. Butane has a boiling point of 30.2 degrees Fahrenheit, while propane has a boiling point of -43.6 degrees Fahrenheit, allowing you to cook at low temperatures.
Some BHO extraction technicians employ a 70%/30% butane/propane blend or various solvent blend ratios. You’ll need to account for increased pressures when utilizing butane/propane mixtures or just using propane as a solvent.
What butane is best for BHO?
Experts believe that laboratory grade n-butane is the cleanest and most effective solvent for extracting concentrates from cannabis when it comes to butane hash oil. This gas was previously only accessible in bulk cylinders from speciality gas suppliers or in portable cans imported from abroad. Puretane, a new American-made n-butane intended exclusively for BHO manufacturers, is now available.
Can I use any butane for BHO?
When extracting BHO, only high-purity butane should be utilized. It’s also a good idea to test the resulting concentration for any remaining solvents.
What kind of butane do you use to make shatter?
For primary extraction, standard low-temperature hydrocarbon extraction conditions are used. Low-temperature extraction, rather than a higher-temperature boiling solvent like ethanol, reduces phospholipid extraction, resulting in a higher-quality, higher-potency end product. In this case, most operators will use a butane-dominant solvent blend or 100 percent n-butane. Too much propane will pull the lighter terpenes out of the mix, raising terpene content and affecting THCa nucleation throughout the batch, causing it to separate “Sugar,” she says.
The residual solvent concentration of the raw oil when it is removed from the machine is our final consideration in this category. It’s critical to leave enough liquid solvent left so that you can gently pour the concentrate out of the machine, causing little agitation and preventing THCa nucleation “Sugaring” the slab is a term that refers to the process of
Can butane be used as a lubricant?
Mystery oil is a gas remnant that leaves many extraction artists scratching their brains as to what it contains. Without the use of a closed-loop system, open-blasting butane results in significantly more mystery oil in the end product. The “mystery oil,” as extraction professionals affectionately refer to it, has a characteristic rubbery and tire-like odor.
Extraction businesses that have done some testing and investigation believe the mystery oil is made up of a mix of components that include longer-chain oleaginous waxes and trace levels of sulfur. A lubricant present in low-quality butane canisters has also been suggested as a probable culprit by web sleuths, but no scientific tests have proven either notion to be valid.
Many low-cost butane cans contain oils that are used as propellants, to lubricate machinery used to fill cans, and to protect the inside from rust and clogging. The unknown oil additives may be listed as “one percent other” by consumers. It is not necessary to list these ingredients. To eliminate the mystery oil, closed-loop extraction equipment can be employed to purify butane and propane.
As cannabis oil extraction has grown in popularity, commercial extraction facilities have been able to obtain higher-grade butane and propane, putting an end to the traditional anxieties of “mystery oil.”
How long should I purge my BHO?
The final step in making high-quality, delicious BHO is vacuum purging. There are a few key points to consider regarding the vacuum purging workflow now. Everyone’s method is unique. The purging procedure for manufacturing BHO is broken out in this diagram.
Run the Vac
Place the BHO in the center of the vacuum oven once it has been spread out thinly on a silicone mat or parchment paper. Set the temperature to your preferred level once the BHO is inside the oven, then gently run the pump to full vac. Set the oven temperature to 110o F once it has nearly reached a full vacuum.
Slow down. As the vacuum is increased, you may notice the BHO bubbling up and producing a muffin-like top, which is the butane outgassing. The boiling decreases over time, and there are less bubbles (this may take a few hours or days).
The amount of butane present in the BHO after the water bath, as well as the ambient room temperature, determine how long you spend outgassing the butane. It will be more difficult to remove the solvent if your room is cooler. To judge the quality of the BHO, many extractors merely glance at it. The vacuum purging is complete when the bubbles stop and the texture and consistency of the BHO do not alter under vacuum pressure.
Remove All Bubbles
You turn the thin layer of shatter on the silicone mat after your desired purging cycle (up to 124 hours), and repeat the operation with the same time and pressure parameters as previously. Your bubbling will be less strong during the second pull, but there will still be some bubbling. You can gradually increase the temperature when the boiling subsides (if you started at about 105o F, you may increase it to 110o F). Allow the BHO to sit in the full vacuum for as long as you want (about 6-8 hours).
Flip the slab of BHO as needed, adjusting the temperature, pressure, and time as needed to achieve the desired end result (shatter, live resin, distillate, etc).
To avoid a mess when flipping the BHO, use PTFE sheets instead of standard parchment paper with silicone covering. Make sure they’re heatproof, food-safe, and nonstick. Solvent-proof PTFE sheets allow you to purge without absorbing solvent into the sheet. Furthermore, its non-stick properties ensure that no terpenes are retained.
On top of the silicone mat, place a single sheet. Using your BHO, transfer it to the sheet. When you’re ready to flip the BHO, place another sheet on top while it’s still warm.
Place the BHO on a cool surface like a stone counter, a chill block, or a piece of cool steel. Allow the temperature of the cannabis extract to drop to the bottom. After a few minutes, quickly flip over the thin layer of extract and peel away the top sheet. When opposed to a heated extract, the cooling helps it not stick as much. If you can’t locate this, parchment paper will suffice. Any non-stick paper would suffice. Transparent sheets, in theory, make it easier to see the product.
Consider residual solvent testing a sample of your finished product if necessary to detect hazardous amounts of butane or propane solvent, as well as other impurities. To detect each cannabis ingredient and contaminant, labs utilize a variety of chromatography equipment.
Is there food grade butane?
Blue Flame is a pure butane fuel produced in the United States to exceedingly high quality requirements. There are no mercaptans, and there are no hazardous lubricants. BPA-free food-grade liner
Is butane used to make dabs?
Dabs are formed by squirting butane or lighter fluid into the marijuana plant, which is a highly flammable and unstable material. It is exceedingly harmful to heat these compounds. Furthermore, any residual butane gas remains in the room once the process is completed.
How do I know if my BHO has butane?
Dependence on butane hash oil is possible, and it has an impact on many people. It is thought that if BHO is used at a slower rate, it will form a habit. Long-term use will surely aid in the development of resistance to the medicine. As a result of this, dependency develops, and withdrawal may occur if the person stops using, prompting some people to use only to avoid it. As a result, a pattern of BHO reliance emerges.
Can you taste butane in dabs?
If your concentrates taste like solvents, you should look for a new dispensary. The only exception is Butane Hash Oil, or BHO, and even then, your dabs should be delightful, not nasty! Also, if you bring a concentration home and dislike the taste, don’t buy it again. Have faith in your taste buds!
What is the difference between 5X and 11X butane?
Butane is a form of petroleum-derived natural gas. Natural gas is quite dirty and unrefined when it is extracted. Furthermore, it is commonly dissolved in oil, which must be removed from the natural gas. In the same way, water vapor must be removed from the gas.
Methane, propane, and butane are the three types of liquids found in natural gas. Natural gas must go through a series of boiling and heating steps to eliminate these chemicals. Each chemical is separated from the gas when it reaches its boiling point. Fractional distillation is the name for this method.
Butane isn’t completely pure even after it’s been extracted. It must first go through a thorough purification and filtration process. Most commercial applications necessitate a gas purity of 97 to 99.5 percent. This is performed by refining the butane that has been extracted a number of times. Refining aids in the reduction of impurities in gas and the improvement of its quality. More significantly, refined gasoline reduces clogging, malfunctions, and misfiring of the burner valves.
In short, 11X gas has undergone 11 refinements, whereas 5X butane has undergone 5 refinements.
There are some distinctions between these fuels in this regard.
5X fuel is one of the most popular butane fuels due to its high purity level. It is mostly used to replace low-quality gas. 11X gasoline, on the other hand, is a typical lighter refill. It’s inexpensive, highly combustible, and suitable for a wide range of uses. It can be used in both industrial and domestic settings.
