That is a pretty huge bummer but that does lead me to the 2nd part or was my primary question, which was what if I just used distilled water instead? I was able to boil water at about 101F with my aspirator setup. But then you mention it condensing and clogging shit up so I dunno. I don't do large runs, typically I usually extract from 1/2 ounce of the most top shelf quality that I can find in my part of Arizona. This is all for my own use and I do have my med card here in Arizona as well, was thinking about doing a round of the cannabis alchemy at the Skunk Pharm labs (since reciprocity is part of Arizona's med laws, which I don't think matters in Oregon but still) but I don't really have the $$ or free time to take off from work so..... hence my trial & error approach...[QUOTE="
My only real question is should I still use my 95% ethanol or should I just go for some distilled water as the water has a higher boiling point than the ethanol. My plan was to perform a "blanket" vacuum distill where I vaporize THC and everything below it, thereby creating an ethanol/cannabis vapor which will condense into my waiting dry-ice chilled receiving flask. Then taking that ethanol solution and vacuum distilling off the ethanol for re-use. Boom, insta-pure concentrate! No? I'm failing to see any downside except for final collection of the concentrate from the boiling flask but I'll just redissolve in ethanol and pour out onto my trusty pyrex dish as per usual and let it air dry for a good while.
I got good news n I got bad news. Bad news first before the good.
Alcohol n thc vapour will not travel together under vacuum or any other condition. ALL your alcohol will boil n condense before the first puff of primary target compounds, then when you get desperate and start raising your temperatures all the resin will re-condense on your coils and if you do a big enough run will completly fill your condenser untill it jams. Then you will have a glorious evening of putting 1 drop of alcohol in the top n having one drip of extract drip out the bottom till its clean.
Your theory on how to clean up the alcohol after your first step should of denoted why the first step wouldn't work.
The great news. I can see my post from june of last year, and I can see my avatar says i came out the other end.
You sound like you have all the gear you need for me to actually be able to usefully share, i don't know how many times i've mentioned aspirator n garden hose.
I don't suppose by any freak chance your in the washington state? "secret cup pnw" I extract with d-limonene n I'm not subject to any temperature problems like what qwizoking mentioned.
Don't feel bad im 16k in equipment debt in search for a higher truth that what the majority will be satiated by
I'm on instagram n facebook and have been featured by bubbleman fresh headies if u want to see some pics.

Sweet thx, yeah I was able to find a couple of sources on food grade and even what one place referred to as "Ultra Pure" at 98% d-limonene. Will prolly end up buying from them. You're dead right on me not being able to waste material. Ideally, I'd like to be doing runs of 1 ounce, I do 1/2 ounce a week and usually run out of concentrate usually the day of my next extract. If I were doing the whole ounce I could more closely follow the gram a day regiment needed for results, again I'm doing this to help my crohn's disease...LOL Congrats! you figured out my trade secret all on your own.
You are! the kind of folk I knew where out there.
You can get it from new direction aromatics....
You are back in time where I was on July 8th 2013 Grrr why can't i upload images anymore.....
Look the limonene route isn't easy, it is very difficult to get consistent results with a magnetic stir bar.
Everything is dandy till 80% of the limonene is gone and your oil starts to get thick. "your oil never leaves the boiling flask your solvent does"
Your stirbar is going to come to a grinding halt and the water is going to start BUMPING. its going to be scary, oil is going to start splattering all over your flask.
You gotta tidy up that aspirator setup you will need -28.5 hg. If your only boiling water at 101f Wait Im so dumb you mean farenheight Im in Celcius it sounds like your fine.
You sound like you don't have allot of bud to loose, so I dunno about venturing outside of the qwet your use to, my first 15 batches I wouldn't even dab these days.
The great news is I'm telling you all this, cuzz purging is hard, its going to take you at least 2 days n you can't leave the stirbar unless BUMPING is what ur into.
Warning number 3. GET the largest largest largest long football shaped stirbar you can find, all of those pill shaped things can't spin oil........Don't be like me and wait 2 weeks only to have to wait another 2 weeks after getting to use it for 40 mins.
I can't write the history of how to get from where you are to where Im at, plus you dont have the money to go comercial gear until you can make at least 1 batch of shatter using the steam distil tek. I slept on the floor for weeks while it ran, so you have to earn your lumps....

I've come to the conclusion, that the reason people blast (make BHO etc.) is that what they are growing in bud form. Or even regular hash, just isn't that tasty or potent...
oh and $800+ for all the proper lab equipment?? Hardly... I got all my stuff for sub-$400 ... that's all the lab glassware for vacuum distillation AND heating mantle WITH magnetic stirring capabilities!

Really the hardest part is making sure you have all the little accessories, water aspirator & condenser hookup stuff, vacuum grease, ring stands, etc. but you don't have to get the official CORNING PYREX chemistry set to do chemistry. If you can then by all means please do and if you do please get some for me since you're so well off lol!
hmm, interesting. I think I've come across sublimation before but skipped over it to look into other processes. When you say, "extremely small apparatus" do you mean like a short path setup? Or is a sublimation apparatus completely different?See the problem you have here is thc, like the other cannabinoids is a diterpene and this class of terpenes possesses a molecular weight much higher than that of the aromatic terpenes that make up the smell, and what that means is regardless of the boiling point, these compounds are generally tough to distill because the vapor will want condense on anything room temperature, for this reason your extract would have to be distilled in an extremely small apparstus where the boiling flask and condenser are relatively close together , a sublimation apparatus would be the piece of glassware i would choose for this application.
I imagine it would be more economical to make a cold ethanol extract to begin with and then after you have removed the alcohol from the extract, place your purged extract into the bottom piece of the apparatus and affix the top piece with your cold water circulation hoses attached to it.
As long as the temperature is held closely around 314 F degrees the thc would really have no choice but to sublimate this would actually save your the headache of trying to steam distill with your simple distillation setup.
It would actually make more sense to try to distill off the terpenes and save them so they can be added back into the Sublimate. The liquid aromatic terpenes may cause the thc to drip off the condenser (Im assuming the terpenes stay somewhat liquid even when they condense on the cold finger) so it would be of benefit to remove the terpenes somehow by simple distillation.
Yeah, I'm aware that pretty much all of this stuff can be jimmy-rigged together if the right McGuyver-type guy is around like yourself, seemingly... I'm not that improvisational in handyman-hardware skills. I'm sure if I just took the time & effort I could hack it but I'd rather spend a lil bit of $$$ and be sure it's not my equipment that's fucking whatever up at the moment. As I become more confident in my chem abilities overall, then I'll start trying my hand and making my own equipment. Gotz'ta crawl before ya walk!Most of these can be improvised.....Vacuum chamber's are so simple.I am currently reclaiming my butane and using a Nitrogen preload Accumulator....I have to add a small amount from time to time but it's Sweet.
Yea, i should have mentioned that a short path distillation setup would still cause the vapor to travel farther than it needs to before It has to condense, so really a sublimation apparatus would be the bees knees.hmm, interesting.
