Because I didn't want to mess up a separatory funnel with the black foul smelling mess, I poured the solution in a 1 gallon Ziploc bag, to which I added equal amounts of water and hexane. If not, there's your problem. Quick question oh wise one, it is difficult at times to purge the extract before heat and agitation render it waxy and sealed in. Especially if the material is preconditioned by some of the other extraction methods. My plan is to just keep doing this to see if they continue to grow. Then I add the ISO/hexane solution + 100 ml water to a separatory funnel, I shake and let settle. Have you personally smoked or vaped extract with dust in it? Or please point the way to where I might be able to purchase the same one? It also takes longer to work the emulsion layer with subsequent washes, and each wash leaves with some, so at some point need to make the call. We warmed the oil and solvent in a pyrex dish in water bath. Method #2, rotovap, or any other way to reclaim. After it has separated, bleed off the water and emulsion layer. Perfect for separations like this. The oil will stick to the dish. We were able to justify the cost based on the number of samples we ran and the cost to have a lab run them for us. Can the solution just be left to air dry for several day's?, or do I need to I was only given crude to do R&D with so every time I would get some id isolate the thca and add it to it, Nice! How long a quick wash at what temperature? I'm wondering if it will be possible to remove pam cooking spray from a run of bho. One article cannot cover the multitude of variability encountered in our pursuit. Then, pulverize/blend into a fine consistently. You could short path vacuum distill the extract. We let it settlte and drained, it looked as if it was going as planned, the water was colored (but no percipitation). I suggest that you start with a small sample and see how it works for you! But, vaping the extract baked liked this turned me on to the fact I wasn't inhaling fully converted THC. Then, reduce the pressure in your system to -30 mmHg, or as low as you can go based on elevation, using your vacuum pump. The far more hazardous thing (verifiable with medical data) to do from a healhwise perspective is to kiss another human or share a joint or pipe. I ensured the solution was supersaturated by adding small amounts of BHO into solution, until no more would dissolve at room temp. American Pot Story: Oaksterdam highlights the journey of cannabis advocates and concerned citizens in California during a time of significant change. What evidence can you provide that suggests the lungs are not capable of dealing with this? @mylkingtrees Ummm dude3, hes referring to the filtering funnel on top of the bottle @Guapo sir the pirce of labware that you are refferring to and that this man is faiiling to correctly inform on is called a "Buchner Funnel" It is usually used in conjunction with an "Erlenmyer Flask" with a vaccum port feature, a filter paper is placed in the filter funnel an a vaccum is applied to the port on the flask, when filtering flow slows down from a clogged filter, vaccum is turned on to assist in speeding up the process. Should you add the everclear to the butane/oil before it has evaporated? No matter how you consume cannabis, the idea is to treat something that ails you physically as well as mentally. There wasn't really enough that precipitated out to smear onto paper to see. I'm also allergic to chlorophyll so I'm trying to kill two birds with one stone and stick to alcohols which I react much better to. Hexane grabs > all of the medicine for sure, but the real point of this article is to show > one posssible use of it. Hi All, YOU MUST START WITH A SUBSTANTIALLY FILTERED extraction to begin with, so a first column run without alumina and just the fine frit filter of a buchner funnel pulled through is HIGHLY recommended at 100% iso as the solvent. Cite. In meterology this is called "condensation particulate" and dust was once added to clouds in an attempt to seed the rain. Filter is "slow" rated for fine crystals. GW. Once the solvent is recovered, transfer your solution (cannabinoids/solvent/terpenes) to a pressure-rated crystallization vessel, which can be any vessel that handles pressure and has a pressure gauge, pressure release valve, and a vent valve. Is it safe to smoke? We haven't figured that one yet. Individuals with nausea may want a capsule or tincture that has a ratio of THCA and cannabidiol (CBD), another cannabinoid with potential anti-emetic effects, and some myrcene to help alleviate their discomfort. I strive to recover the $100 per gallon hexane and other spendy solvents but when they are mixed it is just too tough for me to get a clean seperation so usually they get evaporated. I have my freezer set to max and my thermometer show a temp just under -10 C. The water components freeze and the freezer dries it. While THCA is a useful cannabinoid on its own, the synergistic effects of cannabinoids and terpenes are not to be underestimated. We still send out samples for others material to test for pesticide, but if you know the history of material that you've grown yourself, you should know what you used. There are about a hundred variables that might present themselves with your extraction, but the general prodedure above has been employed by myself for a long time. Any solvent placed into an oven, as in step 2 will ignite as soon as the vapor reaches its flash point. Hopefully, improving processing techniques and purifying cannabinoids will help lead to future cannabinoid-based research so we can begin manufacturing cannabinoid-based drugs for treating specific ailments, thereby moving away from the anecdotes that we have today. Have seen a clear terp online and am wondering If any one has info on how to achieve it. I leave my refined extract in an uncovered petri dish in my home. I have done a LOT of seperatory funnel work, centrifuge work, filtering, cooking, distillation, and have even oxidized away Volitile components of extract with Hydrogen Peroxide by carefully creating an emulsion of extract at elevated temp with (drop by drop) 35% food grade hydrogen peroxide. We are thrilled that our documentary American Pot Story: Oaksterdam continues to get favorable reviews. I do not believe that the presence of salt impacts the relationship that water and acetone have. Water also dissolves and washes away the Chlorophyll binding proteins and exposes the Chlorophyll to the solvent used. The saline exposes any proteins hydrophobic surfaces, making them insoluble in water, so that they precipitate out, and the saturated water has no room for anything but the alcohol, which aids that process. D Gold, Author of Cannabis Alchemy, 1971, Shares Cannabis Extraction History Unfolding! Plus remember that "Hexane" is not the name of a particular chemical but names a group of chemicals with substantially the same characteristics. I can even take the extract so cleaned up and when placed on a cool glass surface can seperate the components easily with a flame above the goop and a tilt to the surface. I placed ~2-3 grams of extract in a 20mL GC vial. This doesnt mean it isn't effective it just means that more understanding is gained with each effort. I think it was moonshine derived but not finished. How long/how many washes did it take to achieve this size rock? Do you have an email graywolf? This is because every extraction can be different. Once the vessel is filled, tightly close and chill it to -75. Added saturated salt water like instructed, shook, separated, and drained water off, and color did not change. Most smokes very little. Isolating cannabinoids to their purest form, such as THCA diamonds, and recombining them with terpenes is the first step in creating treatments that target specific symptoms. Micro filtration is the same thing, but uses a larger pore size, so might not clog as fast and I've installed industrial plate and frame micro-filtration plants down to 0.2 microns. Thanks. You can make nearly pure iso propyl alcohol for pennies by salting down rubbing alcohol. Repeating the last two paragraphs of the article for your benefit: Then the idea behind DCVC is that a continuos solvent gradient is fed through the system starting with an extremely polar solvent. My last batch was all small diamonds. However, I am impatient so I can just stroll down to the quick mart on the corner and get rubbing alcohol. I'm led to understand that salt water is about as polar as you can get and should remove chlorophyll, as well as other polar solvent-soluble materials. But it's dark ! I take the glass which is cool to the touch and dab my goop (wax or shatter or scrapings) onto the glass which is held horizontal. Eventually, the HTSFE will have small amounts of terpenes present with large crystals, or many small crystals, and it will be ready for the final purge. Have already washed diamonds and worked out well. Bake it at 275F-300F until the cooled product is dark brown and crumbles easily between your fingers. GW. I even asked nice. This is my sop (without getting into minute details) it really only is efficient for 100+ grams of thc-a otherwise there is a significant loss The light yellow layer mentioned with acetone evaporated into pure thc judging by the slightly sweet chalky flavor and my commitment to solving Einsteins problem with gravity as a constant in any given inertial frame after vaping some. :). Given our 30ppm taste sensory threshold and our 130 ppm odor threshold, we can detect its presence, long before we reach levels of concern. On average, HTFSE is about 70 percent THCA and 15 percent terpenes. The flame gets intense. What am I doing wrong, can someone please help! Bleed off bottom layer (or what I can semi distinguish as the aqueous phase) and replace with clean water. Creating THCa Crystalline | Cannabis Tech Alas, UV radiation also destroys cannabinoids, but fortunately at a much slower rate, and three or four hours in the sun is usually enough. Very interesting. They list n-Hexane as a class two solvent with 290 ppm concentration limits, and a total PDE of 290 mg/day. It turns out that I don't mind or notice a bit. Are people also idiots who do that too? Salt water washing uses a separatory funnel as above, but we start out dissolving the extraction to be cleaned directly into hot n-Hexane, and then washing the hexane solution with saturated salt water. This HTSFE is comprised of high potency THCA crystals with a layer of terpenes. After I notice no bubbles forming (15min - 1 hr), I pressurize the chamber and pull a second purge. I'm always looking for you folks to clean up my ongoing (and seemingly neverending) RSO apprenticeship :-) Invalid username/password. From the sounds of it, you say you can't get it to dry out. Are you using 70% ISO, thus taking advantage of the containment of water to dissolve the salt? The waxes left over, by the way, work GREAT as a skin softener. If I can be told a more effective way to evaporate the Ethanol, or even better a method of producing a hard shatter consistency with strictly ethanol? That is called a "Seperation Funnel" they come in various sizes. DISCLAIMER; I do not condone using this method where as any extracting methods are consider dangerous. In column chromatography, which takes HOURS for even small samples and simply cannot handle larger samples, a solvent gradient works by passing a solvent through the column that has very little or no ability to disolve the sample and carry it through the stationary phase. It helps purge the residual butane. I have done many experiments with hexane, acetone, alcohol, and ethyle acetate as well as water. 2. GW, I've asked our chemistry brain trust Pharmer Joe to also share his thoughts, but my first thought is that a warm methanol extraction would be chock full of extra stuff, that as you've noted is difficult and time consuming to remove. into the stainless steel container the mash is in whilst still hot after coming out of decarbing in the 250 oil bath. I've looked into carbon filtration a lot, but this is the first time someone gave an actual number as to what is lost. I do not extract but from time to time get flower to puff. He is surprisingly open to conversation. Some MMJ applications require greater purity and potency, so it is desirable to remove inactive ingredients like fats, lipids, and plant waxes, as well as any chlorophyll and other water solubles. Here is what a winterizing filter cake looks like, while still wet. Vapor respirator. At this point, I have concentrated it down to a very potent, yet very dark matter. Is this the correct thought process? The issues I am having is that I do not get a distinct phase separation between the water, emulsion and hexane layers. We've observed that when evaporating 1 liter of methanol, hash oil starts forming in the last 50ml. The mind change is unmistakable. Here is one techique that can remove any impurities soluable in water - specifically alpha pinene. My lab thermometer goes down to -10 C and it is colder than that. It can however, be fractionalized by adding salt. What I just typed is how I would attempt it. The reason is that with a cookbook recipe we can be certain when we add flour, that the flour is as pure as it gets. Washing dirty diamonds - Crystallization - Future4200 I come back later and the iso mix has turned white from the waxes and the oils with the magic precipitate out. About 2-3 inches. The hexane was much brighter, but when we purged, it came out pretty black. Finally, if you really want to see the separation, obtain a glass tube. I tried this with some older trim that was run with butane. Light smoking will occur if particulate is present - the goop oil will stop smoking though. DIAMOND MINING WITH LIVE RESIN : A step by step guide to the Protocol: Winterize the RSO oil in ethanol and filter out waxes, then distill off the ethanol. The water layer will be milk to chalk white. Its also a thick honey texture, which is kind of a pain to work with. It works without question and the only product loss will be the polar compounds which will not pass the alumina column. There are solvent polarity charts online. After this time, remove the vessel from the cold environment, open the vent valve, and allow the solution to reach room temperature. Before delving into how to make that process work, may I ask why you've chosen to extract with warm methanol. Are you up for a challenge ? It is amber and clear and can vape with very little respiratory irritation. Modified mason jars or stainless-steel reactors are most often used depending on scale. Post my progress back up wen I get back from vacation an my pentane comes in. Here is a link to a DIY evaporator that addresses that issue. Anyone I can email with or speak to? N-Hexane boils at about 69C/ 156F and has a high vapor pressure, so it is easy to evaporate, but harder to completely purge. In Flash Chromatography you NEVER let the column go dry or it fails the column. Leave the vacuum on to dry the crystals at the end. I like iso because it falls in just the right niche polarity wise to target the medicine. It would eventually air dry in a thin film, but vacuum is so much faster, and more reliable. I only have one video which only shows one step and how effective the process works just as a pure filtration method rather than seperation. It had 1/2 dram of LorAnn raspberry flavoring in it (PG, color, flavoring). I did mine with left over jar wash and trim runs that people had laying around, My first attempt yeilded bigger diamonds then the hot jar tek. In minutes it hardens into tiny air pocket ridden pieces. Below 10 degrees celsius, outdoors, not frozen 90 seconds wash. 2023 Wise Education Technology Inc. All rights reserved. *A strainer works well for seperating the rather pure thc-a from the chunks I evaporated and purged at high vacuum the yellow layer by itself and the dark hexane layer.
