Since everyone keeps asking and it seems no one has started a thread here I might as well.
I am not taking credit for this by any means just showing what I've learned. I found out about this through toke city. If you want to find that thread then google vacuum purge toke city.com
anyways the theory is to create a vacuum inside a container causing the butane to bubble out of the oil
This method doesn't require heat (though it does help speed things up if it is warm) and ensures that all butane has left the oil.
Personally I still purge on a warm dish because I do multiple runs so the oil sits for a while.
Once the oil starts to thickin up I begin the vacuum process.
On to the tools. A vacuum sealer or hand pump one will not get the pressure you need. The best tool is a mighty vac hand pump found at most automotive stores, used for bleeding brakes.
Now there are a couple different methods. You can use a mason jar or just create a lid for the pyrex dishes. The smaller the container the better as there is less air to pump out.
I created a lid using a piece of plexiglass and rubber. The vacuum pump comes with a suction cup which is perfect for this. I simply drilled a little hole in the center.
then you just pump away. Here in CO i've only been able to get up to 21 and it's takes a lot of pumping.
at sea level you should be able to get it to 25 or 26.
I usually purge for roughly 30 min. and will release the vacuum and pump it back up twice.
slight warmth is nice at this point as it will make the oil more viscous allowing the butane to escape easier. The main benefits of not using heat are that the color will not be affected (oil darkens with heat), you aren't decarbing of the thc or cannabinoids and the oil maintains a more consistent and presentable appearance. Often butter is due to to much heat, though I have come across many a strain that auto butter.
I'll post a step by step of how the oil reacts later.
