also true, oxidized copper is no good either.

Think this test tube will work for BHO?

in the "Wiley guide to chemical incompatibilities"
there is ABSOLUTELLY NO mention of copper reacting with butane. odd?
you are maybe more experienced than the Wileys (200+ years editing the guide now in its 55 ed.)
hehe

I recently saw a BHO tutorial here on ICMag where dude was using copper pipes, I questioned him, but was not sure if it was toxic or not..

this tripod fits as many tubes as you want to tie on to it
4 is the max we done at a time, but we got 6 tubes.

Nice one. Not.
Nice one. Not.
I DID use water grade piping, I cleaned it out before hand, and the oil still tasted like kaka. I'll never use anything but stainless or glass. To each their own. But thanks anyway. Just for the record, I never said it reacted "violently", I just said my oil tasted like shit, I assumed it reacted with the copper. Meh, don't matter now I guess, huh?
I know my stainless won't tarnish, and my oil tastes GREAT. Have a nice day.
Nice one. Not.
yo all
i agree with jump 117
i have been making the greatest darn BHO ever, only using COPPER extraction tubes.
anybody saying copper reacts violently with butane doesnt REALLY have much of a clue of what he is talking about.
does not affect flavour in any way.
ONLY possible reason for YOU getting a BAD flavour using a copper tube, is because YOU were not using a clean copper tube to start with. any normal coppertubes designed for transporting drinking water will do.
i have worked in the metal industry several years in my youth, and i know WELL the process of manifacturing tubes of metal.
when the metal sheet-rolls get shaped into tubes, they are lubricated with an emulsion, that IN ALL NORMAL CASES GETS WASHED OF..
so just going to a normal plumbing shop, get any tube you want, (pieces longer than a meter is quite awkward for filling and emptying.)
but DO NOT fear using copper for BUTANE extraction. all my old tubes are still as shiny and clean and nice inside as when i got them and prepared them.
use CLEAN TUBES.
not much to add - any questions - feel free to ask.
stainless steel works as well, also important to use clean material.

insults? what are you talking about?
it seems obvious you dont know so much about chemistry, how could that be an isult at all?!?
anyway;
I DO RECOMEND COPPER
its safe and wont affect flavour.
i have never heard of any issues of using COPPER during my times at the online forums.
i also did one "HOW TO" thread back at overgrow that got a wast amount of views.
im sure if any of these 1000's of people that read the thread and used my method, would have had any bad experiences, im sure i would have heard about it.
but since the fact remains that butane doesnt react with copper...
the flavour problem of you BHO must be of other reason.
dont take it bad. we are here to teach and spread information, not to make up facts to suit our own needs.
DONT get me WRONG - i believe you when u say your BHO tasted BAD.
im only saying the reason is not the metal used.
it was because
A . tube wasnt clean (remains of lubricant emulsion)
B . bad butane. (mercaptans taste bad)

As an engineer, I wonder who started the rumor that butane reacts with copper at the temperatures that we are working with?
Copper compounds are used as a catalyst to refine N-Butane at elevated temperatures (200/520C) but are non reactive at extraction temperatures.
Smoking copper oxide creates the same health problems as fume fever, a welding health issue when welding copper alloys with out respiratory protection.
Butane does not however corrode copper and unless you are using tubes with green deposits created by other exposures, it is hard to approach .1mg/M3 MSDS TLV exposure for fumes.
It is easy to keep your copper wiped clean, so I wonder how it ever got to be such a topic of concern and debate.
I started out using copper, never had a problem, nor did any of my participating patients ever notice any copper flavor.
I have concentrated on raising the medicinal potency, while eliminating unwanted flavors, and in point of fact, I get as many comments on the pure unadulterated flavor of my extracts, as their potency.
I switched to glass from copper or 304SS, simply because I can see what I am doing and would use copper or stainless again in a heartbeat, should the need arise.
What is the problem keeping the equipment clean? Would you eat out of a dirty dish? Would you ban porcelain because someone got E-Coli from using a dirty one?

PS: Copper pipe does come with die lubricants on it, so special cleaning is always necessary for inert service duty.
Although they don't for potable water service, as a matter of taste, I recommend doing the same, using a good solvent and swabbing it out like your favorite rifle before using the first time.

this is the kind of posts i like to read.
informative and educational.

Wow, thanks for the enlightenment, I was under the impression copper was bad from bad hearsay..very good to know. Thanks Bonecarver.

As far as small batches go I use a perscription bottles and butane and a mug. Its super easy just poke a hole on the bittom tube, and punch a bunch of holes in the cap. Wedge a coffee filter inbetween the cap and bottle and viola.
Buying lots of cans of butane looks odd, and as of late I've had some QC issues with the quality of butane. I've been getting chunks of ice in the recieving dish latley and never got them before. Also strange smells of end product (no good).
Because of that I've made my own machine using propane tanks. I can post the specs if anyone cares to know, but on the cost side, a tank of propane costs $30, about the cost of 10 cans of ronson butane. I made my machine for like $45 including tank. With cheaper gas your able to fully extract more product. I always would screw myself because I would want to shoot the most with what I had. Now I can do pounds at a time no problem.
It amazes me that people actually buy premade extraction gear. All of it can be made with little to no money, just be smart enough to know what your doing, petro gas is flammable. If you have ANY question its best to come here and ask it first then end up like somebody I knew (toasty!).
Copper is fine to use, the reaction your thinking of is in referance to natural gas, NOT butane or propane. But if your still paranoid use black iron, thats top of code. I had this arguement a long long time ago in a chemistry board far far away.
Propane works just as well and is just as safe as butane. Co2 is the best but then your talking big bucks for equipment. Your Higher pressures mean bigger better more $$$ gear.
If anyone can point me to a super cheap Co2 setup (<$75) please let me know.

good post
but where do you get pure propane? most stuff has hella mercaptans added for safety...

You dont need tech grade propane (if they even make it), just make sure you do a good ethanol wash afterwards.
I've tried both and propane seems much better to me, past 2 years it seems like butane has changed in formula.
Any residue would be washed out with an ethanol wash, use double the volume of etoh for eatch wash if your really paranoid.
But personally it tastes, smells, and smokes just as good as Co2.
