Thank you, I was able to find one with ease thanks to your link.

Fadedawg do you know anything about solenoid Valves? I want to use one to let out bursts of the liquid CO2 into the collection vessel for depressurization. But I am having trouble understanding how they are rated for pressure. I can't find any that mention pressure above 145psi, but a few of...

Yes, thank you. Now that I take a closer look the aluminum CO2 tank has a service pressure of 1,800psi, and a 3,000psi pressure test. Whereas the carbon fiber tank has working pressure of 4,500psi, a pressure test at 7,250psi, and a minimum burst pressure of 15,000psi. (Those are rounded, it...

Are these scuba tanks the same as standard aluminum CO2 tanks the pressure rating seems to be the same. I can only find carbon fiber scuba tanks that are rated to 4500psi, and aluminum tank that are treated for 3000psi. I've decided to swap the 45g CO2 cartridge for a 316 stainless steel spool...

Yea especially cause those systems don't include the 20lb C02 tanks needed for it which run around 150-200 each.

Yea one of the reasons C02 might be more desirable as an extraction method is because it preserves the terpenes better. However supercritical extraction can still cause some degradation to terpenes. I've read that the process for getting live resin through C02 is too freeze dry the flower, and...

I've never actually tried a C02 distillate. But I do share your sentiment it is an incredibly clean extract.

I mean to be frank you're not making sense as some of your statements contradict reality. There are actual people extracting terpenes independently of cannabiniods and waxes, and people extracting terpenes and cannabinoids separately from waxes.

To touch upon the statement you made about not being able to extract terpenes, cannabiniods, and waxes separately. In fadedawgs article he mentions the option of doing an extraction at 850 psi(in the subcritical range) to extract only the terpenes, and then doing a second higher psi extraction...

Well it made at least a little sense to me. I will admit that I don't have an extensive knowledge or much of any education in the fields of engineering, electronics, or chemistry. It was my understanding that C02 is a tunable extraction method, and that is one of the reasons one might choose C02...

So even if I could be sure that the 20mpa is the operating pressure and not the burst pressure these cartridges would not have a high enough rating for a 1500psi extraction. For subcritical with the highest pressure being 1100psi(3300psi rated tank needed for safety) it would work if the 20mpa...

Ideally I would like to find a seller that can tell me the actual manufacturers specifications for the cartridge. Unfortunately I haven't been able to thus far. Most sources quote the 20 mpa that it was tested by the seller at. But one and only one mentions "Maximum pressure resistance: 25MPA /...

Both the gfistainless, and the eagelstainless links lead to a website but not to the product mentioned. Sorry my message was riddled with typos. I was wondering what vessel you used for the collection not the extraction. The one you had a link to eaglestainless.

It's a little concerning to me that the pressure rating is from a sellers test, and not from the manufacturer. But the seller is offering videos of pressure tests.

Also, sorry if my previous comments seemed a little rude. Charles upset me by saying it was not possible to do diy C02 extractions. I came here to hopefully gain some insight into a serviceable collection vessel that I can use. Not to have a matter of fact denied by someone.

Ahhh I see, it's a good link. Your article was incredibly helpful. Unfortunately all of your links to products are no longer serviceable. I was wondering what type of vessel you used for the vessel. That end is used to depressurize so it should need such stringent pressure ratings. The 45g C02...

According to the sellers description they have been pressure tested up to 20 mpa with no leaks. Even if I run supercritical extractions I only plan on going up to 1500 psi at most, so even if I had to directly hear the material vessel I shouldn't even come close to the maximum psi (though I plan...

I plan on pre heating the full C02 tank before starting the process. It's still not perfect, but it does work. I am going to be running subcritical extractions, so I can really only extract terpenes and cannabiniods. As liquid C02 isn't a strong enough silent to pull out waxes, lipids...

For sure you can't use equipment that's not rated for the pressure you need to do it. I don't know why after succeeding in extraction he would say you "need" a pump. I see that you haven't read his article.

Crazy, cause I read his article that he linked...... and he not only said that is possible, but that he had done it.
