good catch there shisa, yeah filter the hexane/material mixture before adding the ethanol. good luck dude, be sure to post back here with your results.

honestly i have no idea, abysmal would be a better person to ask regarding ethanol. i myself cannot find anything higher than 70% locally, i need to do some more hunting online for a vendor with reasonable prices.

i would run it again, and stick the second run in edibles, or if you don't mind the taste, you can vape it.

ive heard of people getting returns as high as 50% with dry sift extractions, so i would estimate that 100 grams in would yield somewhere around 45-50 grams if the starting material is high quality.

you do not need to vac in between adding the ethanol to the hexane/material mixture, though you can if you desire. also remove the activated carbon step, it is unnecessary and every instance i've read about people using activated carbon with concentrate making is that it leaves behind a nasty...

one more thing to add about polarity in solvents, polar solvents can dissolve both polar and non-polar compounds quite easily, non-polar solvents are more selective in what they dissolve. for our intent and purposes, non-polar solvents will always produce a more pure product with ease, while a...

yeah hexane would be easiest aside from butane, i was going to mention ether and chloroform as well, though they are much more dangerous to handle, and im sure harder to find as well.

if your goal is an absolute, nonpolar before polar is the way to go.

yeah that butane should be fine, isobutane and n-butane are good to go, as are commercial butanes, though i would definitely be more wary of the commercial brands.

qwiso + ethanol makes no sense, both are alcohols, both are polar solvents, the only difference in the two is that ethanol provides a cleaner taste than ISO, and is not as readily available in its un-denatured form in all areas. butane + ethanol will be your best bet for an absolute, or another...

redissolving in a nonpolar solvent after using a polar one for the initial extraction would be pointless.

i agree with everything in this post, except i've been an underdog owner for a bit longer. log vapes are very efficient, simple to use, maintain 24/7 capabilities so you can medicate at any given moment if you desire, and can be quite heavy hitters, i can vouch for underdog's cloud producing...

yeah, but filter it before pouring into the pyrex, the kief will still leave plant matter behind. this was the results of my first kief ISO wash, i believe it was a 20 second soak, and it took awhile to filter through the coffee filter, so i estimate another 20-30 seconds to seep through...

a 6CFM single stage should be fine for your intended purposes, keep in mind that a vac should be putting the finishing touches on your purge tech, not used to get the majority of the tane out. i would double boil your oil on a low heat, perhaps 140-170F, though others prefer different temps...

why not order a kif box/sifter. im surprised everyone on here doesn't already vape dry sift, as most modern grinders have kief catchers these days. love adding a little dry sift to my runs, increases the yields and always results in a tasty oil albeit darker oil.

if you feel a vac is unnecessary, then you definitely do not have a proper vacuum setup or are not using it properly.

yes you can wash flowers in ISO.

i would consider myself a healthy weight, perhaps slightly under the norm, last time i weighed myself i was around 120, and i am 5'7", so pretty short and skinny

mercaptans are present in all commercial butanes, or so i've been told, but i have found zero evidence supporting claims that they do not evaporate along with the rest of the 'tane. that just doesn't make sense to me, especially since no residue is left behind on a surface that (quality)butane...

im not too familiar with PSI, only inches of vacuum measured in hg's, so i have no idea what that means. a better question would be what kind of pump setup are you using? ideally you should be pulling the vacuum while your oil is in a molten, almost liquidy state to ensure the escape of...
