Freeze precipitation.. Possible to have to much solvent?
    #24024688 - 01/20/17 03:00 AM (7 years, 1 month ago)

When doing a extraction would one need to reduce the amount of solvent by evaporation before freeze precipitation? If one has a very very small amount of solvent and needs to make it last as long as possible could it be possible to skip on evaporating? or would that result in A smaller yield?

Could one Just use 50% less solvent then "needed" and just do more pulls?

Also do you think using a wooden spoon is bad?
I make sure to keep it soaking in distilled water so when i stick it in it doesnt suck anything up, i feel like my spoon is filled with deems at this point lol

Yes...Reduce before freeze precipitation...

you can try skipping the evap...I'm interested to hear what would happen if you do..

Nothing wrong with wooden spoon...I like chopsticks for stirring...

Generally, you don't need a lot of solvent so a 50% reduction may or may not affect yield..it all depends on what tek you are using..???

I am Using q21q21s tek because how east it is.
but im in cali and have no napatha so i am using heptane but the company

bestine went out of buisnes and i only have 1000ml of heptane left.

its a 200g so i guess ill try to start with 100ml of solvent and ill hope for the best

The point of pre-evap is to make sure that the solvent is saturated enough to allow the DMT to crash out easier when you put it into the freezer. If its not saturated enough it will take longer for the DMT to crash out and some DMT might even stay in the solvent(if not saturated enough and if the freezer isn't cold enough).

Having the solvent as saturated as possible is better. There's two options you can do now:
1. pre-evap a significant amount of the solvent before sticking in the freezer
or
2. Stick it in the freezer as-is, and after a day or so of precipitation, retrieve any crystals that might have precipitated and reuse the solvent for more pulls (meaning the unprecipitated dmt wont be lost, it will be there for next pull), or if its your last pull, evap it till the end to retrieve the rest of your dmt.

Also, if you use 50% less solvent but more pulls, wouldn't you end up using the same amount eventually anyway? More pulls with less solvent is considered better, for the record. 5-6 pulls with 50ml each is what I would go with.

5-6 50ml on 200g sounds good to me, I second that. Op, you know you can reuse your solvent right? If you have 1000ml and plan to get more bark in the future, which it sounds like you do or you wouldn't care about wasting solvent, then just keep reusing the 250-300ml that you're going to use for this extraction.

As TGO just said after crystallization, if you get crystals (and you should with 2g in 300ml), then your heptane will already be saturated with dmt at your freezers temperature. So what this means is if you then do not reduce it to crash out more but instead do another 5-6 pulls on a fresh 200g of bark then theoretically ALL of the newly extracted DMT will crash out because the dmt that is already in there will effectively push it out. So if you keep reusing it you will always get everything extracted at the cost of a small part of your first extraction.

Alright thx for the help everyone i have a good idea of what i will be doing now.

I think im also going to leave it in the fridge/freezer for awhile and then put it in a chest with some dry ice after it slowly gets cold.
And like you guys said i can just evap when im completely done with runs so if i decide i need more them 50ML of solvent it wont be the end of the world.

On another note, what consistency do you go with?
I seem to lose some solvent most of the time, I keep it kinda chunky but Also i try to keep it as saturated as possible so the solvent can just pass through the bark but not be absorbed. 

But i have read having it "soupy" works also but i feel like the oatmeal style is easier to work with.
