Bump!
Taio, Gray Wolf has posted this info earlier:
"A 250F final purge removes the monoterpenes and loses that "fresh" smell and taste, but still produces good resin. It won't produce shatter, because 250F partially decarboxylates it. We get shatter reliably at 115F and -29.5"F, which tastes and smells exactly like what it was extracted from. "
For the butane purge, I keep the temp around 110-115F. I use an electric skillet with the butane container in water set to 110-115. (If I understand correctly, the low temp helps preserve the terpenes and thus the great smell and taste). I don't let it go too long, maybe 1-2 hours. I then stir up the oil to remove most of the bubbles. Then I add the Everclear and stir it up some more until the butane looks to be dissolved. I can see the wax starting to separate at this point. I winterize the alcohol solution for 24-48 hours. After filtering the solution, I do a long, low temp purge of the alcohol solution, 2 days on a seedling heat mat (probably around 80F). I am very happy with this tek because it produces great quality smoke reliably. It took me a few time to get it right, but now I think I have it dialed in. Too bad winter's going to be ending soon.
Nice bro, but it seems to me you're saying you used a standard vacuum pump to filter the initial butane/oil solution, and the general consensus is this is an unacceptable risk factor. A water aspirator for cheap, or a safe pump like a Welsh are practical and safe means to supply the necessary vacuum.
An inexpensive ;-) Welsh,

They've this little baby, doesn't pull a really deep vacuum, but should do the trick for the specific application,

Purdy oil! Hows the aroma, flavor, and effects?
I would rate both aroma and flavor 9/10. Aroma strongly resembles the flowers. Flavor does as well, but there's a more prominent citrus/cherry taste (which I like).
Effects are good. It's a strong sativa but not too racy. Definitely not the best for the night time use though- I tried some dabs of it last night and was up for a couple hours later than usual.
As SH notes, a diaphragm pump or water aspirator would be safer than using a sliding rotary vane pump.
can the mixture of solvent. pull shit from that plastic ? or is it not exposed long enough to do anything?
