Small Run BHO Technique

[Detective Dank]

 

Jump: is this a good summary of the thermos extraction part of your process? (If we're assuming they don't want to make Absolute Amber, just regular BHO)

1. Place buds in the "extraction thermos", and place that into a freezer for an hour or so.

2. Take everything outdoors and spray pre-cooled butane into the precooled "extraction thermos", and let the buds sit in the liquid pool of butane in the thermos for a while (an hour or so?).

3. (Still outdoors) Pour out the butane into a pyrex dish through a coffee filter, and purge using as little heat as possible.

The extraction thermos being anything that is both resistant to butane and can provide insulation. The pre-cooled thermos (and butane) keeps the butane a liquid while you soak.

I've always really wanted to get into this extraction style as you could do whole nug runs and get maximum efficiency.

edit: Absolute amber would require then washing the oil on the pyrex in ethanol, then taking the new solution and filtering it through a coffee filter into a clean pyrex, and evaporating the ethanol off. Have I got all this right Jump?

Hey Detective Dank! perfectly described, thank you.

Thank you for coming up with such an awesome extraction method and documenting it so well!

edit: oh yeah, how well will this process work with dried and cured marijuana? Should i shorten the soak time a bit?

The process works well with the juicy, and the dry material.
The state of the material, is it dry or juicy, grinded or whole, affects the extraction of pollutants from the interior of the plant body, but not the resin from its surface.

Soaking time depends on the temperature of the solvent, the colder it is, the longer the exposure.
I'm cooling the can and stuff in the thermos to -20C ~-4F, so adjusted my freezer.
At such low temperatures the first half of the resin is dissolved in 20 minutes, and the second - over the next two hours.
During this time, the temperature remains practically unchanged and the evaporation of butane is not happening.

Although it would be enough to cool to -1C ~30F, just below the boiling point of butane, but I did not.

Tiny chip of AA made from dry.



Soaked 2 hrs 30 mins in -20C butane.

wow jump that looks fantastic. Hey, can we see a picture of how you are consuming that lovely golden sap? I remember your wooden pipe (which was really sweet) from a while back but also remember HMK telling you he'd send you some TI soon thereafter, and I would just like to see how you smoke/ vape that stuff!

Damn, jump and detective dank... I might have to give this a try

Awwwwweeesoooome I am so down to try this, I'll post process pictures when I do my big 420 grab.

Alas, here I have nothing to boast. I use various DIY devices.
The current prototype is made of the soldering iron with open ceramic heater, bottle and hose, without water.
This is a fairly coarse unit, even awkward to take pictures.

Yes, 06-20-2010 is unforgettable. It was two years back on 4th page of ~BHO LOVERS~ (click).
Of course, I would be delighted to receive a copy of the legendary author's device,
it would be great pleasure and great honor.

But I have often opposed HMK in various discussions.
It seems somewhat unethical to request to the person whose views I have mercilessly criticized.

Couple of newb questions, bout to do my 1st run hopefully someone can chime in and help. And to help you help me heres some info:

Im using roughly an 8th of ground material (could be slightly more or less I didnt weigh it out just stuffed my extractor till I thought it was well packed)
Ill be using a very small GonG extractor by The Rev.

First question I have has to do with the size fo the dish you guys are spraying into? 2nd, Im still a bit confused on when Im supposed to stop spraying so Im not wasting tane and elongating evap. time. Am I looking for something visually to change?

Thanks in advance for any help!
