Hi, The smoke is horrible so I don't believe any THC is left at this point. Last month I dropped a hot beaker I was refining on my hardwood floor. The mix will clearly seperate into multiple layers. This time, a lot of stuff percipitated. Once unwanted seeds form remove. In honor of 4/20, Oaksterdam University Executive Chancellor Dale Sky Jones speaks with Karina Nova at ABC7 News in the Bay Area. in Free. In my humble opinion, you are doing it absolutely right. The process is known generally as Dry Column Vacuum Chromatograph (DCVC) although the only references I find online relate to the method as used with silica gel as the stationary phase. I shook the mixture well and let it soak for a day to extract the material from the roaches and scrapings, before straining it through a wire strainer and then a coffee filter. Please suggest. The layer that is amber and clear is the good stuff. Google has tons of stuff on it. But not 1 single rock. Post my progress back up wen I get back from vacation an my pentane comes in. He is surprisingly open to conversation. btw 98% is completely false. Hexane has been unpredictable for me in the seperatory funnel in terms of repeatable results. I do not extract but from time to time get flower to puff. From your post I assume you are also after THC. Looking forward to your video! In a nutshell, many water soluble non cannabinoid ingredients come along for the ride when a polar solvent is used and water is present. 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? I pre-heat my oven to 250 F. I put the iso/extract mix now onto a preheated cookie sheet. Also I have bled off some of the bottom layer and replaced with fresh water, even after 10 additions of fresh water I notice no color change in the system it is still dark and nasty. dissolve it in rubbing alcohol completely. Any solvent placed into an oven, as in step 2 will ignite as soon as the vapor reaches its flash point. 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. Continue the evaporation until complete. nobody recrystallizes their THC. Because brother, I have found when refining dispensary extracts; fitting grease, eye lashes, tiny flies, unidentified dust bits and have added on accident some of ose those things myself. A vacuum of -15 to -20 mmHg should be used to assist the purging process. Extremely potent this way, likely owing to the possibility of DEEP lung inhalations without coughing. Without additional processing, it produces a more full-spectrum product called a high-terpene full-spectrum extract (HTFSE). This presumes that your goal is to remove the chlorophyl only. Also wanted to polish BHO with Everclear. Do you do this with your cold crash crystals ? My plan is to just keep doing this to see if they continue to grow. When you add salt to the mix it is very tough to know how that impacts things. I have redissolved it into fresh ISO and have it in the freezer separating from a saline water infusion. I am thinking of peppers. Link to a pdf of the issue here. June 29, 2022. I filtered the hexane and poured that into a Pyrex pie plate, which I blew air over with a fan to evaporate off. I leave my refined extract in an uncovered petri dish in my home. Doing so will evaporate most of the butane. If you intend to produce a THCA crystalline with above 99 percent purity, you will need to perform these washings. Routes of Entry: Absorbed through skin. Note that my system is based on iso/water because it is simple, effective and extremely inexpensive compared to other systems but without a doubt other systems of solvent used as a gradient thusly would likely be more efficient. That hasn't been my experience where over saturation had helped to precipitate out of the fats, definitely hard to find that balance and I'm not sure the advantage would be worth it, It only matters if your going to put into your crack pipe.. I've looked into carbon filtration a lot, but this is the first time someone gave an actual number as to what is lost. How long should i wait before the ethanol is gone, always seems to have a slight smell to it. The picture was my ex-spouse. An eyelash or two, inevitably some hair, and always some dust. I generally see the best results going from the most non polar solvent (hexane) and proceeding towards the least polar solvent one step at a time in the seperatory funnel. #10 add big seeds( at this time your saturation and purity levels should be ideal.) Repeat this in 5% increments until the system is 100% isopropyl alcohol and you will be left with 20 samples. 6) The seperatory will reveal at least two layers and in the first stage sometimes a third. Same with the eggs and so forth. The most effective way that we've found to remove the residual hexane, is either with multiple ethanol washes, usually around three, or thin film vacuum. While n-Hexane is a delightfully non polar solvent, that enables us to do some amazing things, it has two more carbons and four more hydrogen atoms in the chain than Butane, and so due to the greater Van der Waal forces involved, is not as easy to get rid of as Butane. I discovered diamond painting in early 2020 and haven't . We used 20 grams of oil and around 200ml of Pentane & Hexane mix. Solvents in Class 2 (Table 2) should be limited in pharmaceutical products because of their inherent toxicity. washing diamonds with pentane I use a medicine dropper to remove the amber layer. 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. I think it was moonshine derived but not finished.
