Next attempt.. Need opinions

Alright, so SWIM is going to try his third attempt at an extraction, and wants to make sure he does it right this time.

SWIM uses 3000ml water and 200g rootbark each time, and both times he got under 1% spice.. He still needs to get his technique down apparently.

Now here are his questions:

- Does it matter how long you let the MHRB basify with the lye before you add naptha to pull?
- Heptane: Where do you get it?
- Is it better to use heptane to pull instead of naptha?
- Is it bad to let the naptha sit in the jug for an extended period of time?
- How long, typically, are you supposed to roll and separate naptha for before pulling?
 
you seem to have a pretty good recipe going there, I assume you also add 200g lye? Maybe add some more lye, it never hurts to add more. I usually do when I'm not getting good yield or on old soup.

to answer some of your questions:
- Does it matter how long you let the MHRB basify with the lye before you add naptha to pull?
I like to at least let the bubbles go down from the reaction. this seems to help keep emulsions down to.

- Heptane: Where do you get it?
The internet?

- Is it better to use heptane to pull instead of naptha?
Never really used heptane so I dunno..

- Is it bad to let the naptha sit in the jug for an extended period of time?
no, leaving it in there allows it to draw the dmt from the solution. I sometimes leave a small layer on top while storing.

- How long, typically, are you supposed to roll and separate naptha for before pulling?
I like to wait 24hrs for the first pull, rolling it every hour or so. 2 days for the second and 3 for the third. also adding lye for the 3rd pull.

Hope that helps :]
 
Does adding lye on the 3rd pull actually help? How much do you add?

There is nowhere to buy heptane outside of the internet?
 
re: heptane, I was under the impression that it was a weaker NP-solvent, and so it was preferred for recrystalization after pulling with naptha.
