i was looking through the threads here and noticed nothing on concentrates. so far it seems that this is pretty much a chem forum but i didn't think it would be too extremely out of place to start this.

i'm working with two bags: my 220 micron work bag and 73 micron pull bag. not using the drill, i don't trust that thing, i use a large, no-sharp-edges paint mixing paddle.

this is headband x chernobyl. picture taken in early morning sunlight. this was AMAZING. very high oil content, clean white ash and it positively danced while it bubbled

this is mr. nice and afghani kush, got the trim from a different source. the quality of the trim wasn't as good as the first, but it still bubbles and tastes great. **EDIT** forgive the weird green spot in the middle of the picture, i took this one inside at night and the camera on my phone is somewhat bunk.

i've also been experimenting with oils and i've pretty much gotten it down, i'm using acetone as the solvent followed by a triple water wash, dewaxing and decoloring. the results up to now have been good (albeit irritating because some bulls*** happens and f***s my yields every now and then. pretty soon (once i have the glass) i'm going to synth some chloroform, as it pulls 99% of the cannabinoids in materials within 30 minutes, so i'm really excited to see how that turns out. will post pics of oil when available.

Why not use butane supercritical fluid extraction and get an even purer material with WAY LESS work?

IMO, butane extracts, really arent that pleasurable to smoke compared with the product of the "Bubble Bag".
Its not that much less effort either, if at all, and there are other negatives associated with the quality/price of butane when processing anything over an ounce.
Those big Chinese canisters used for camping stoves etc look ideal, but they leave you product tasting like arse.
Only the most expensive butane will work around here.

ChinaCat, Do you press or heat your product, or any other process post-bubble? Curious, as a friend has tried most of what is described on the Pot boards, but in every case it resulted in a loss of potency and flavor. Found its best to just ball it up and leave it alone.

Edit : Ah, sorry Dopamine, I see now what you are referring to when suggesting the butane extraction is less effort.

Yes I agree, Butane much better idea.

There's at least one thread where these matters are discussed here:

I hope this isn't breaking any rules. I've never tried their product but they seem to have a system that actually recycles the butane. If somebody was interested in professional use of supercritial butane extraction for any purpose and especially if they cared about conserving butane, this seems like a quality (but expensive) method. Personally, I don't have a problem with the quality of the butane from lighter refillers. Anyway, check these guys out: http://www.tamisiumextractors.com

Why not just get two very small coke bottles.
1. Drill holes in each lid that tightly fits tubing - put the tip of a pen in the tubing and pull it tight -- this helps seal it off completely.

2. Fill one pop bottle full of butane and marijuana, screw on the lid, and after letting it soak, tilt the bottle so the liquid butane runs through the tube into the other pop bottle.

3. Place the pop bottle now full of butane + extract in warm-ish water or just leave it sitting out and place the other in ice cold water + salt to condense the butane that wants to boil off from the other pop bottle... just simple distillation.

You could have the pot get washed several times, and easily pinch off the tube and refill the pop bottle with new pot. etc... and continue the process without ever wasting any butane, and you'd get all of the oil in one pop bottle.

I had made something similar before for extracting stuff from dried peppers and pepper seeds. If you get the nice small 12oz coke bottles they hold the butane just fine it seems -- but obviously it might be a hazardous thing. What pressure can pop bottles hold? and what is the vapor pressure of butane? If you put them in the freezer the butane does not boil and the pressure is very low - allowing you to safely open the bottle. IIRC.

a bit of info on pop bottles: http://forum.allaboutcircuits.com/showthread.php?t=26261
And at 50*C butanes pressure is like, 74 PSI -- sounds like it is pretty safe to me if bottles can easily hold 120 PSI - esp. if you keep it a bit cooler than 50*C which will almost certainly be the case...
So I guess a pop bottle easily holds double the pressure needed to keep butane liquid at room temperature? Possibly they hold much more pressure...

See attached picture to get what I mean about the pen tip... Not sure why, but it totally helps.

The issues brought up in:

https://the-collective.ws/forum/index.php?topic=10386

are possible problems

Polymers dissolve in organic solvents, thus the use of them can be dangerous in many ways

There's a lot of published information on this subject online, one applicable article is attached

embezzler · « **Reply #7 on:** March 23, 2012, 10:26:43 PM »

What is the liklihood of the polymer absorbing some of the product with a solvent like butane present? Or leaching out some of the hardeners increasing health hazards during consumption? Bottle life would prob be much shorter too

I would suggest something more inert... like the WD thread suggests

( it took me until about post 10 to understand WTF the OP there was on about until I noticed what forum it was posted in !!)

lugh · « **Reply #8 on:** March 23, 2012, 11:01:08 PM »

Only scientific testing will determine how much of the product penetrates into the walls of the bottle, and similar means would be needed to determine how much polyethylene terephathalate contaminates the oil

It seems likely considering what happens during other procedures carried out in such containers

The attached dissertation describes some of the parameters

embezzler · « **Reply #9 on:** March 23, 2012, 11:47:56 PM »

Interesting document to speed read... I didn't appreciate the impact of base hydrolysis on the bottle integrity before. Many of the details in the dissertation confirm your statements and my suspicions that the bottles will both absorb goodies and release nasties into the solvent and aside from the safety this is reason enough to avoid em.

(also I never considered the implications of compounds absorbed into the polymers during their first life and subsequently released during recycling and re incorporated into "new" bottles. )

Chloroform is reportedly an excellent solvent for cannabinoids, but word I've heard is that pentane, hexane and diethyl ether are more selective solvents.

Of course, when your starting material is that gnarly, even an ethanol extract is potent and smooth.

most definitely....why fuck around further? Bubble hash can bee AS good as V good Afghani hash and fresh speaks from personal experience with both

I am surprised at all this talk, when the cheapest easiest solvent would have to be EtOH no if buts or maybes!

Takes longer but works a treat....chop-soak-FILTER..lots of coffee filter papers with no vacuum, slow but very effective

The end product after good filtration and evaporation is HONEY oil...every time! from leaf, buds whatever..its was the seedy shit fresh would use
