You guys may want to consider your health a bit more when considering your building materials. Risking your health to save a couple hundred bucks is a bit silly if you ask me. For starters, acrylic, polycarbonate, and silicone should not be used anywhere near Butane, Iso, or Ethanol. Second, JB weld or other epoxies should not be used either. Basicallly when you are working with the three aforementioned solvents, you want building materials to all be made from stainless steel, aluminum, brass, glass/boro/pyrex, PTFE, Polypropylene, and a few other materials are ok. Here is a chemical compatibility chart to reference...

Another thing is storage, its terrible that silicone containers have become the most popular medium for concentrate storage. Silicone is not safe at all with the chemicals we use. Silicone and butane are a huge no no(very incompatible) so, any residual butane not purged from your concentrate will interact with the silicone and could be causing you harm. Ethanol is not very compatible with silicone either. Iso and silicone are ok though.

I wont even get into the dangers of untested/McGyvered vac chambers and drawing large amounts flammable gasses through a non-gas rated fan/pump:doh:. The only words I will add is SAFETY GLASSES AND FIRE EXTINGUISHERS PEOPLE.

Please people, we need to start being more careful with what materials we use. You are better off to just stick with flower if you can afford to purchase the right materials to make concentrates safely. Keep it safe guys and keep your health in mind:tup:

ok... what exatly am I looking at parts wise? looks lie an ss bowl and an ss dog dish? is there a measuring cup too?

with the vacuum filter wider is definitely better!

Haha exactly that; a dog bowl and measuring cup. I went to goodwill to scrounge up some parts and these two fit the bill. I used a dremel to cut off the bottom of the measuring cup, as well as cut a hole in the dog bowl, then epoxied the two together. The whole contraption sits on top of the pyrex bowl I use for purging and is sealed with an o ring.

I think you should read before you comment. Every material I've used (with the exception of the acrylic in the first version) is either butane resistant (ethanol and isopropyl as well) or not in contact whatsoever with the butane. I use absolutely zero silicone. Vacuum hose and filter felt are made from polypropylene.

I'm well aware of the fire potential but I consider the practice extremely low risk. First off I'm doing small runs, using less than 150 ml of butane, and the pump is only run for ~ 5 seconds. The vast majority of butane does not even touch the vacuum, as it is shut off as soon all liquid butane passes through the filter.

I did read and I was talking to everyone in the thread(hell, on this site), not just you. Really, I should have started a new thread with this info as I constantly see this kind of thing on this site and I wonder if most even know the risks. I see people using acrylic and polycarbonate vac chambers all the time on here for butane extraction even though both should never be used around butane and most other solvents. The same goes for silicone containers, silicone coated parchment paper, silicone oil slick pads, exc. And, butane is a gas at room temps so, it is in contact with everything on the inside of the chamber including any epoxy used to seal any fitting or parts together. Any metal parts should be welded together and any glass parts should be fused or sealed with polypropylene/PTFE compression fittings exc.

Not trying to be an ass or a safety nazi, I just want people to know the risks and help clean up the concentrate world:tup:

Not meant to be condescending at all, just informative. Sorry if I came off that way. Not everyone knows about chemical resistance and interactions or the dangers involved. Fewer accidents and less contaminated concentrate on the market is good for all of us dude:tup:

pardon for dropping in here and asking a newb question: How much can I expect the quality of my oil to change by using a vacuum setup instead of just a heat purge? I have made BHO oil 3x now, but it fails to blow me away. I am wondering if the heat is killing some of my goodies. Also what is a good size for a hobby guy like me? I see those chambers on ebay in all kinds of sizes, tall, wide, flat...!?

No worries. And to answer your question, a vacuum purge would likely significantly improve your oil. I mean that mostly in terms of flavor, because unless you're purging at temps close to 300° I doubt you're losing very many psychoactive cannabinoids (and in turn potency).

I use a 6 quart vacuum chamber but that's only because I made one myself. If was buying, I'd definitely go smaller to save some money (like 3-4 quarts instead). You want a lot of surface area so it's better to go wider/shorter than taller/narrower.

If you have anymore questions, this concentrate thread should be able to help you out:
