well if its pyrex its good for temp. fluctuations like that. sounds like it is maybe since you heat tested it but its broke now so its all useless conjecture

Think this test tube will work for BHO?

You might consider heating it up and punching a hole throught the glass like a glass blower would do.
Though handy and priced right, your tube is a little small for much production. As it is pretty cheap to have a glass blower make a tube for you out of 1 1/2" Pyrex tube stock, you might investigate that as well.
See attached scientific grade extraction system, using such a tube, and a chopped up scientific grade cat litter bucket for a stand.

whats the thing stuck up in the end of the tube and whats it for graywolf?
Hi HK!
It is a wadded up coffee filter to keep particulate from blowing back if I get interupted and to spread out the butane flow faster.

farout, thanks for the clarification.
Hey Capn, I was messing with the DIY style for a long time. Did a couple of incarnations with metal tubes (my first one I used copper! ICK!), did a stainless turkey baster (worked decent). No decent glassblowers in my area, so I ended up grabbing an okief tube, works great, makes me some mighty fine BHO. After you feel like buying a ready made version, check out okief, they make some high quality stuff.
Now I just need to get a bell/Ti pad combo from Aqua Lab!

Hey Capn!
You're trying hard to make an extractor of glass. Excuise my irony but it's like making a nail of a glass.
It reminds me an old saying - "Too much loud and too less wool", - said devil trimming a cat.
Glass isn't easy to work with and accessible connections aren't effective enough.
If you want to get an extractor that is chip, reliable and easy in service look closer at water-supply pipes and fittings.
You don't need to be handy with metal, all the parts I mean are ready-made in a shop, you only have to buy and assemble it.
It may be made of steel or bronze or inox - that doesn't matter, metals do not react with butane.
All you need is a tube 3/4" with pre-made thread (Pipe Nipple) on both accurately prepared ends suitable for flange gaskets instead of thread compression, two paronite flange gaskets, cap and nozzle (Barbed Insert Adapter).
You may also buy several tubes of different lengths and get thus several extractors of different volumes using the same end-fittings.
The only metal work you have to do is to drill an opening in the middle of a cap that is suitable to butane can nozzle, it's approx. 2,5-5 mm depends on nozzle type.
First place a metal gauze into a nozzle, next paper filter, next gasket and screw a tube.
Load a stuff. Screw a cap with gasket. Now it's ready to use.
Do not allow the nozzle to touch anything while extracting to prevent static spark or/and ground the device.
Thread connections are very strong and you'll never meet blow-off effect. Loading and cleaning is perfectly easy.
Notice that butane like all another liquids find an easy way to go and passes by a blind areas of higher density of a loaded stuff especially when cross section of extractor is large.
I've studied a residue oil-cake after BHO direct flow extraction through the microscope, there is a lot of good resin stays there.
Look to study an alternative BHO technology - thermos flask type extractor. It provides more complete washing and independent on density of a loaded stuff.
I hope you willn't figure my post agressive or selfish

I had a bad experience with copper, it turned me off to it. Better off sticking with stainless or glass IMHO.

people used copper tubes for a long time i thot tho. i never tried one. surprised myself. some kinda residue maybe..?

Thanks the part that worries me the most jump, as I have really horrible luck.
I actually have one of these thurmoses around here somewhere. I think mine lost its rubber gasket tho so it would prolly leak butane everywhere if I used it.
I'll keep an eye out for another one tho, I see em all the time at garage sales.
Thanks alot for the info budgood/jump!!

I had no copper tubes in use, my ones are made of steel.
I suppose it wasn't copper by itself but it's oxide or any of it's salts made your extract so bad.
2 Capn
Gaskets play a significant role in tube-type extractor where the pressure is high inside and may cause leakage
but in thermos flask extractor a gasket is useless, there is no pressure in it,
a stuff is floating and stiring in liquid butane while flask throat is open.

I think you're right on that. I'd still HIGHLY recommend that people use stainless or glass though, it's worth it to eliminate one more variable to making high quality BHO.

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.
peace
