Whats up RIU!
I have been making extracts for a number of years using commercial product to create many fun experiments (have even launched my own consulting and canna-product line) and have a FOOL PROOF standard method I have used for a good 5 yrs solid and am sadly moving more and more away from as short pathing (distillates) have become a new premier product. So, for all you Lab nerds like myself, here is a little gold on making the best alcohol extract without breaking your bank or ever bring the temps above freezing for live flower lovers:

I am going to put this up front, you will need to invest about $400-$500 to continue with this process, turn around now if you aren't willing to use the necessary equipment. There is no 'rigging' shit up cheaply here :) this is lab level extract you will be creating.

What You Need:
1.) 1oz produce - I will scale this for 1 oz of quality raw produce, multiply by your amounts, this will never procuce much if you use less than 1 oz, again commit to the process if you're gonna make a run!

2.) 99% Isopropyl Alcohol (if you can only find 91%, use your step 4 item to create pure iso alc). ISO is far superior in this type of extract for many reasons, but ill lead with the #1 - Under 99%/29.62 vac it boils at -4C. All vacs should hit 99% easy (adjust for elevation you CO and WA folks). You will NEVER have to bring this extract above a room temp if above freezing once you get this down. ISO - it reigns supreme for this reason alone in my book and yrs of experience.

3.) Unbleached coffee filters

4.) Vacuum Distillation Apparatus (eBay, $40) but you'll need a reaction vessel (add $150, also suggest eBay) you will use the reaction vessel instead of a boiling flask.

5.) Vacuum Pump - this is a range, I personally suggest you invest in an aspirator style pump as it is way safer in your lab and for the environment. Yes, a $55 amazon oil fueled pump WILL work and pull 98%+ Vac. but so can a $20 aspirator and a $40 500gph water pump hooked up in a bucket for constant flow (theres a gem for you cheap asses) without sputtering exhaust and oil all over your lab area

6.) Mason Jars - go for wide mouth style larger ones, makes it easier on yourself an only a few dollars difference

7.) Buchner Funnel Kit ($50 Amazon) - consists of Buchner funnel and Erlenmeyer flask

8.) Heating Mantle - I suggest when you buy your distillation apparatus you get a heating mantle to fit your flask and reaction vessel size. id suggest getting a 1000ML vac distill and 1000 ML reaction vessel as well as 1000ML equivalent heating mantle.

9.) Water Pump for your condenser and Water pump for reaction vessel bath

What You Do:
Ok so now you have all your gear to get started, like i said it's a small investment but the fact you can now make lab level extracts, spirits, and other fun experiments is pretty rad and alone worth it. So on to the process, here is what you do with all these items:

Step 1 - The advantage of this process is that the extract will never have to reach an above 30 degree F temp preserving all terpenes and cannabinoids. FREEZE these items 24 hours before the process: The Isopropyl Alcohol, the herb, the mason jars (i fill the mason jar with the herb and toss in freezer along side the alcohol bottle).

Step 2 - Once all is frozen, add the iso alcohol to cover the herb (sounding like your standard iso wash so far) and shake shake shake

Step 3 - Let sit for 90 min, 90 exact min. Every so often, continue the shake shake shake. Fuck what you hear about swirling and all that treat it delicate weak shit, we're trying to get trichs and terps here! Seriously, this process is for pro level extract, your other 'rules' need not apply.

Step 4 - Place 3 coffee filters in your Buchner Funnel, strain your contents of freezing mason jar into Buchner funnel and use vac assist to drain it all into your erlenmeyer flask it hooks up to (use back of spoon to assist in pressing herb to get all the liquid out). Place the herb in a baggie or something and use in a soxhlet for full plant extract tincture or something to that nature, point being it still has content we just got the grade A out so don't toss it.

Step 5 - Take this frozen clear green liquid you now posses in your flask and pour it into your reaction vessel hooked up to your Vacuum Distillation Apparatus (i suggest using a Vigreux column for glorified bump control if you suck at temp regulation) . This is where the magic happens. So, like i mentioned in the materials needed section ISO is supreme for its extreme low boiling points under vac. Hook up your Vacuum distill and kick on your vac! Now the magic happens. I suggest taking a pot or small bucket and filling it with room temp water to place your reaction vessel with your solution in to maintain a standard temp. your water pump going into your condenser needs to have ICE water going into it and i place a small glass of ice to hold up my receiving end flask of the apparatus to keep that whole side cold and attractive for the alcohol vapor. The second water pump is to pump luke warm/room temp water in/out of the pot/bucket of water your reaction vessel is sitting in as well so it doesn't get cold (the vessel is going to be freezing temps se need to cycle the room temp water most likely through some slight warm water in say a pot on a hot plate set on low). Keep a thermometer attachment hooked to your reaction vessel so it stays at NO MORE than 5C. try to keep steady at 0 to -2

Step 6 - Wait about 2 hours and all your iso will be on the other side of the distillation apparatus, and whats left in your reaction vessel is the best quality extract that has yet to see above freezing temps :clap: Be careful as your reaction vessel gets lower and lower with alcohol as the temps will want to rise causing spikes causing bumping causing your goods to potentially splatter all over your apparatus and you will cry painful tears.

Thats it folks, from there once completed the extract is shatter consistency immediately unless you want to heat up around 20C to caramelize the natural sugars so you can suck up in a glass lure for dab darts. I have used this to make some of the best vape cartridges around for a while until I finally consistency figured out the straight Short Path, fractional SP distillation, and not that I'm great but playing a ton with the rotovap into chromatography tubes!! Trying for them unicorn tears baby (crystalized THC for those unfamiliar)

I rarely post, but I love this community and wanted to share a little gem that has made me some of the best extracts of its time but i know as far as my place in the industry goes is being phased out. From my lab to yours, I hope you can give this a whirl with immediate success and pleasure in the outcome!

Tests wise, I was able to achieve 88% THC as the highest ever tested with this method, standard was around 82%. yield wise, expect about 15% return on AVG. It's a give and take, toss in all prime GG4, get 20%+, toss in some smalls and trim or some jack herrer or some old school green house seed co mid grade level strains and get 10%ish.

Ask any questions or feel free to chime in on your experience with similar process! Good luck, happy extracting, and don't hold me liable for any dumb shit you do or bud you loose attempting.

I did an iso run once but it was my first time
And i thought it tasted gross
But i may have done it wrong

The next batch i made with grain alcohol tasted better. But i might have just made.it better lol


Thanks for the write up

Only take 3 minutes to wash 80% of the meds off the herb, for a nice golden product.
Fresh frozen makes a real fine product.
Still has to be decarbed for ingesting though.
We used to heat it and wash it for days! ...30 years ago

This method is for high quality dab and vape meds so heat will be added :) , I Soxhlet the remaining stuff and clean it up with carbon and celite to remove chlorophyll and fats/lipids then that right there is the best ingestion meds I’ve had to date. Soxhlet does dual purpose of extraction and decarb at once

Thanks for posting. I was just wondering why you suggest a heating mantle if ISO has such a low boiling point. Also, what are your thoughts on a slightly more expensive short path kit that includes a chiller, pump, heating mantle, ect.?

Great question! So, when you run something under vac, it actually brings it well below freezing in most cases (Isopropyl being one of those things). As crazy as it sounds (get in a lab and play around you'll see the challenge) you have to add a form of LIGHT heat in order to be able to bring it even to 0C. Thats why i suggest a good mantle or for cheapies, use 2 pots to circulate slightly warm water in and out of water bath for your vessel.

All I pretty much do now is short path and chromatography..... the only ways to achieve consistent % in the mid to high 90s and it has swept the industry as a whole at the moment i know. I have access to extensive lab equipment and yes chillers, a glass woven digital mantle w/ magnetic stirring, kick ass reaction vessels to hook into the short path head, with fractioning columns for the aftermath to make crystalized THC/CBD, all the amazing things I never had while learning this stuff years ago are great to have however i know most won't have funds or access to that.

The purpose of this write up was to show a method used to create that grade AAA extract used to create some shatter or dab darts or vape pens or all the other new wave of extract products alternative to Butane based (that shit is poison, a byproduct, it's the diesel to already dirty ass gasoline) ones that swept in over the past 10-15 yrs and achieve these results investing only $400-$500 to get going. This will get you the high high quality stuff, especially using live material, that I see so many write ups that lead to inconsistent or dangerous outcomes and misleading info on. Heating things up to 100 degrees under vac to purge, creating BUTANE o_O holding chambers to soak the Plant in (yes, I'm dawging butane/propane closed loop extractors people get hustled on),'just let it evap bro', those types of things to ME, and again my opinion, are what will forever give inconsistent and dangerous results leading to continuous bad reputation for our thriving and capable industry.

Any pictures please?
it's been a bit since I ran this method so nothing current on my new phone, but from about 3 yrs ago when we decided to try live as a larger scale thing, I have this as my 1st test outcome on my PC saved in a memories folder of all our 1sts and sentimental shit like that. I have tons of pics ill dig up for you someday but this was live batch one, you can see material used as i cut it down and then the resulting extract:

Natureboy!! Yes man I would always soxhlet the flower used after this process to get ingestible grade. this process left plenty in the buds still, just took that good good off the top :). I used GWPharms write up when i read it mainly to try celite filtering to clean it even better but for me it's still not as dabble and clean, just tooooooo much comes with the heat. This process will keep everything cold the entire time beginning to end until user decides if they wanna raise temps for consistency. ISO in my experience is way cleaner and doesn't bump nearly as much if at all once lab gear is dialed in after some runs. Ive ran so many butane, alcohol, bubble bags, rosin press, and even ole blender water hash extractions back in the day and this is by far the cleanest most pure and safe method I could come up with and use to make amazing products for a lot of operations. The next level of cleanest for me is short path and chromatography tubes :weed: currently not running to much of this or soxhlet these days but will bust my personal gear out from time to time to get a live run in when I get some airy lower branches out of my personal room.

very nice.With some help from Gw I've been able to produce some nice oil.last winter i got quite a few runs in with the soxhlet and learned A LOT.wasted probably a half lb too lol.the closest testing site is 3 hours away from me so i mainly make edibles with my finish product which are real nice.i like etoh because i have zero issues consuming some residual if they're there.i just got done distilling off a run.i need a good pump.took a chance on a welch off of ebay and im afraid it didnt pay off.ive got an oil driven one,but you know how it goes with those.maybe if i could run it from outside...
i've got some nice indoor i'm going to run through the soxhlet.i havent done any extractions in a few months,ran some outdoor this latest time for practice lol.

YES SIR! Here are completely other strains to prove QA over and over:

Another strain I kept pics of plant with as well:

I mainly sucked these up into glass luer locks or put in vape cartridges. A lot of these batches are LARGE scale. wanted to mainly share some love back to the community on making some extreme quality with decent dry or live product that a lot of those extremely expensive lab tools used essentially do using #s at a time.

Hi, thanks for all this valuable information. I just want to ask a question, why do you use a reaction vessel instead of a distillation flask? Is it to empty the extract more easily?
Thanks a lot.
