Any tricks to optimize pulling???

My least favorite part of the process is pulling. Between the distortion looking through curved part of mason jar, the thin layer of naphtha, trying to get large eyedropper tip barely in, but in enough it does not suck air, pulling base into the eyedropper and it is stuck to it, so any further attempts are contaminated.

Just did a pull and picked up base (lower dark solution) and had quarter size black spot in tray to freeze. Then eye dropper had it sticking to it.

I poured off the naphtha into a graduated cylinder, and black stayed in dish. Think I probably wasted a bunch of dmt wiping the black crap out and washing.

I am using quart mason jars. Should I pull and make sure it is pure, and give up when I pick up anything else. Then use turkey baster to pick up rest of naphtha, with base, and shoot into graduated cylinder, then let settle and suck of top layer?

Is it OK to have black in the dish with naphtha and DMT, and just do re-extraction before using?

Should I suck off the top with baster, and am not careful, getting both layers and shoot into graduated cylinder, let settle and siphon from there.

I am just looking for some experienced advice on how to pull with as little problems as possible.

Was also wondering if ehrlenmeyer flask would be good to pour off.

Also do you use organic respirator when pulling? I do in garage, and hold breath near it, and take breaths about 10 feet away. When it goes well takes less than a minute.

TIA

Yes!

And its not illegal to leave a little bit of naphta.. Dont need to be cheap;)

I'd say that's overkill. It's refined naphtha you're using, not benzene! That said, better off safe than sorry, I suppose.
 
I have grown to really love the smell of Naphtha. Especially sweet when I'm pouring it off ice cold and the smell is a mixture of solvent and magic.

I've found erlenmeyer flask a useful tool for doing the pulls, because the solvent ends up in a narrower part of the flask than the mother liquor. Easier to pull than out of a mason jar imho. There will always be a small amount you can't get. Just leave it, you're doing another pull anyways.
 
Thanks for the replies. I noticed when I contaminated a tray with the black solution and poured it off into another tray, the naphtha flowed easily while the black stuff did not. Will get an ehrlenmeyer to experiment with.
 
My favorite smell is the tray after all the solvent has evaporated. Amazing so little can smell so much. I have not yet re-extracted yet. What I have collected is all yellow. Life sucks so bad, still do not think I am ready to breakthrough.
 
Using an extraction vessel which narrows at the top helps. I use a Voss Water Bottle. Not optimum like a proper flask but they are readily available and the seal in the cap is resistant to both Lye and Naphtha. The large size of the cap helps in getting an even seal as well. In the pic you can't see it but the glass neck narrows under the cap.

Also I use a lavage syringe to draw up the charged naphtha or limo, making sure to rinse with water between uses to avoid degradation of the plunger seal. Again, not optimum like a pipette but they work way better than a turkey baster or eye dropper and are cheap and easily available.

From experimenting, shooting it into a 250ml mason jar with large glass eyedropper, the base (dark bottom stuff in jar) sticks to the bottom of jar, and easily pour it of into glass tray. Then wipe the black stuff from bottom of jar with paper towel. Wish I knew that ahead of time. Trying to decide if I should wash all the extract with naphtha to get rid of base contamination and keep yellow/full spectrum, or do re-extraction for pure DMT.
