Excellent video! I have a question: We are working on CBD extraction from cannabis flowers, and I wanted to know what proportion of dry flower mass to volume of 96° ethanol is usually recommended for the extraction. Thank you very much.
RIP Horatio Delbert. Died from head trauma in a major pressure release event during a co2 extraction in Canada around the time of this making actually. He was a smart guy who took great care and concern in his extractions.
There will be accident in every protocol we exceeding. No depends wich materials we working with. No use to statistics, the thruth is there and will stay.
This Guy is an unbelievably talented and incredibly intelligent being!!!!! He EXCELLED in ALL of his studies making him a HUGE threat to ANY extraction operation in production HANDS DOWN!!!! Not only does he have experience in the equipment but he has the formula for facilities! Solutions! The team at ExtraktLAB has something rooted inside of the m that most companies in this field lack. Integrity. Hats off to you and your team Dr. Thompson!!
Denatured ethanol can be cleaned with molecular sieves. Heptane has a different boiling point as well; isn’t it all removed during degassing and distillation?
sorry i really never know the result of extract co2 will there be any difference if we use ethanol as solvent ?? please inform the difference in the results .. ?? while the raw materials I usually use are sandalwood, cloves, etc., all of them are herbs (essential oils), are there any differences in the aroma and character of the resin, thank you,
I was an ethanol operator and a CO2 operator for years. We switched to ethanol to preserve terps, on subcritical extraction. Your cost of operations breakdown, is clear. CO2 is the way... and with a cold trap to collect terps prior to extraction, we are going 100% back to CO2 and we are confident and assured.
Not sure if I agree with your assessment of cost of CO2 to that of Ethanol. Yes distillation power costs, but in your discussion you didn't mention the percentage of ethanol recovered and reused. Time is a factor, and your use of ethanol is still costly. I don't know about selectivity but it sounds like CO2 has that beat hands down. So, I still am not sure which direction to take. Great work though.
I encourage you to do your own homework on this. Take a look at our calculator at www.extraktlab.com/resources the operating cost differences are orders of magnitudes apart in favor of Co2.
Loving the channel! Learning a ton. I would love to see a video comparing a few various hydrocarbons. Most curious about propane vs butane, also would love to see a budget analysis on those to compare with CO2 or ethanol.
There was one fatality in Oregon with a co2 system at the place I worked in Oregon but that was honestly a time bomb it was home built by a tweeker I refused to go near that... But I'm on the fence well there that was like just co2's fall or the fact that people that didn't know absolutely anything are the builders but that alone could give a bad name
Depends what you're end product is. If straight to distillate and isolate, I see no reason why you shouldn't use ethanol. Scaling a post-CO2 winterization system and waiting 24-36 hours to move on to evaporation is just cost prohibitive in time and equipment. For cost, $250,000 will get you a 1,000lb/day system from extraction to isolate using -30C ethanol, and you can have sellable distillate or isolate at the end of the day. Concerning solvent residuals, running ethanol with n-heptane 5% is perfectly safe; heptane bp is 98C, ethanol 78C at atmosphere. Wiped film temps for CBD run upwards of 165C and under mid to low vacuum, I guarantee you from dozens of California Cat 3 tests (the strictest in the world) ZERO solvent is left in your final product after that. TLDR CO2 is my choice for full spectrum, ethanol -30C for distillate and isolate.
@@extraktLAB “ND” = not detected, ie none of whatever you’re testing for is present in detectable quantities by chromatography. There’s another method you did not mention that completely eliminates the winterization process…hydrocarbon extraction followed by distillation. Much faster and economical. I don’t even touch ethanol anymore.
Not much to say or refute other than your pressure washer analogy. Pressure washers create the pressure on demand and release it immediately. There is no holding tank or pressure vessel involved. It pumps the pressure directly into the hose. The danger with co2 pressure is in the holding tanks and the amount of time the pressure must be held.
What was your favorite argument?
All so far / dang.........also QWiso is soooo bad !!
Selectivity as applied not only to rec but Medicinal

Equipment failure, or operator Error ?
He was using a BHO column with brass nuts for Co2 +limonene extractions. Co2 extractors do not use brass nuts.

@@extraktLABours has brass nuts 🙃

Wow...thanks.
I finally found someone that can scientifically explain CO2 vs Ethanol 👍🏾

But which one is more flavorful or aromatic?

I will bring this up and see if we can accommodate :)

You should probably watch the video. Also. there is no such thing as zero solvent left in your product.

@@extraktLAB 0% and 100% are marketing wank. In the real world neither of those exist.
Hello sir I need help with my research work for biofuel work. Where I can contact you sr?

Can you tell me all the pros and cons about co2 extraction?
I must be missing something🤔
Seems that they extract the same and safety is the only concern...
not a mention of stripping out all terpenes....the MAIN point of creating extractions besides the effects!
4 cents a pounds for co2? Where do you get it?
You probably need to have one of very large co2 tanks to take delivery of a large quantity, Industrial pricing.
ethanol is very safe and cheap ... but for terpenes is very aggressive...
Selectivity is king when going for terpenes!
@@extraktLAB what does this mean? sorry newbie here
Water distillation is good
It works but there are pros and cons. 1. hydrosols. 2. breakdown due to high temperature 3. selectivity 4. yield. Pro or con depends on the botanical.
Wheres that laughing ass buddy of yours that nevers stops giggling? Your better withiut him being so obnoxious ❤
CO2 feels much better on the lungs imo
I disliked because of the misleading and click baity title👎👎
Also made sure that I don't get anymore recommendations from this channel 👎👎👎
Still feel tha way you did a year ago on this subject ?
LMAO THIS DUDE
