  1. I would suggest changing your solvent. Ethanol is a polar solvent and cannabinoids are nonpolar. Use pentane instead, it's more expensive then ethanol but it boils at a lower temp (39 degrees celsius) and is non-toxic. The lower temp helps keep the cannabinoids from breaking down. Also you won't extract as much chlorophyl and terpenes, as those are polar compounds.

  2. For THC bath or heating temperature should be as much low as possible in order to prevent active principle disintegration and perhaps chlorofill extraction as well. In general higher temperature ease process and make extraction faster. But for this kind of compound i suggest to use the minimum temperature , just check the boiling of flask solution: it should'nt be so vigorous. Moreover the condenser: incoming flow from bottom, outcoming flor from upper part, otherwise colling process won't be uniform.

  3. I found your video looking for incor because I'm about to get a soxhlet kit. This was HUGELY HELPFUL! Thank you so much for showing your mistake and progression. That was so helpful. Thanks for sharing your knowledge on this mate.

  4. So your water flow on your condenser is wrong, it always goes in from the bottom and out the top. Also your source flask is too full. Seriously you don't know what you're doing.

  5. Youre condensor setup is like shit, because the water must fill the entire condensor to guarantee maximum condensation. also, the surface of your condensor is nonoptimale. thats why your driprate is so slow. I guess, your extraction had last for hours?

  6. The condenser cold water should feed from the bottom inlet an drain from the top. Also you can buy thimbles that fit your soxhlot diameter that gives a much more even wash path. I've tried both and it's also less restrictive. And heating mantles can be bought online that will match your flask size (half way up). PS: try Petroleum eiter (30-60*F) as a solvent but use it CAREFULLY in a hood with the oxygen displaced! Flood it with nitrogen. Very explosive but very selective for just thc only so very little green comes over. Enjoy✌🏽️

  7. You can use a porcelain, glass, or metal bowl or pot with sand, high heat oil, water, or BB's and immerse your boiling flax in this. The substance used to transfer heat will depend on what you are doing. Sometimes it is desirable to transfer heat quickly and efficiently (BB's), but sometimes one wants to transfer heat more slowly (sand), such as in fractional distillation.

  8. your water flow in your condenser it backwards. Usually the inflow is at the bottom and the outflow is at the top. You can see the condenser isn't getting completely cooled down. maybe your pump isn't strong enough, sometimes you have to run it upside downXD.

  9. you decarb it (and potentially ruin it) as you reboil the solvent.  Not too good to let your active extracts be subjected to such heat for extended periods of time, it destroys the alkaloids.

    Color is another biggie, it is Dark Green, which means you have extracted a sizable quantity of Chlorophyll.

  10. First you need to introduce tube with cold wather on the bottom of the refrigerant. You can separate oil with simple distilation of alcoholic extract. Should know that preparation is prohibited in some countries.

  11. I have also heard of people using centrifuges as well? I want to know if there's a better way to clean out the chlorophyll so I can change the coloring and thc percentage?

  12. can you put your alcohol with the extract when its still warm or hot in a special dish, and put it in the freezer? maybe let it cool down first? and than the extract will just sink and freez wile the alohole stay liquid, than put the alcohol in a dish and back in its bottle.? am i right with my thinking?

  13. with this method, i woul never extract something that have cloropfyl in it….get yourselve a screen an collect the tricomeheadd and steams, a 100 micron screen woul doo the job…than extract the the product you will get from the screen..of course you have to need more beginnig material for this

  14. in germany its called "Benzin DAB" (DAB – Deutsches ArzneiBuch) and its not neurotoxic, its for use on human.
    altough you have to purge the oil, till its like glass and there is no peteth. left!

  15. @Jumbonot: Use a cast iron tea kettle, and suspend your RBF in water. Use a thermometer to keep the water temp to just less than boiling (Will change with elevation: 212F @ Sea level, 194F @ 4000 ft)

  16. Good god! Don't use petroleum ether! Use lab grade diethyl ether, and do it in a well ventilated area, with no open flames. (Petroleum ether is HIGHLY neurotoxic)

    What did you use for solvent in this vid?

  17. no! without EtOH, this will extract the Green. I mean You have to take Petrolether with boiling point between 40° and 60°Celsius.
    n-Pentane is the important component in petrolether, when you become n-Pentane, take this! Be careful with fumes!

  18. make sure you get all the air out of your condensation tube before use, the water splashing on it like that is begging for an accident, also you will condense more vapor. Also you don't need to de carboxylate ahead of time the temp of the water vapor is enough to de carb

  19. Do a secondary wash with a non polar solvent like hexane and it will only pull out the non polar volatile plant essences leaving the polar water soluble stuff behind. This is best done when taking the oil from the first extraction and freezing it for a few hours.

  20. Many videos are planned for the future….right now I'm working to perfect my hard candy recipe and my pain relief topical liniment. To purge I simply place a one cup jar in a very small crock pot, with a mineral oil bath, and allow the solvent(acetone) to boil off. I then allow it to cool and solidify and examine the properties of the resultant "standard oil" to be certain that the acetone is fully purged. I then allow it to sit for a day or two to evaporate any water that might be left over.
