Argon Exit Bag help: I just need to make sure i'm purchasing the correct equipment e.g regulator e.c.t

[notuntilperfection]

So I've found a 5 litre pure argon cylinder with pressure of 200bar - 2900 psi, which i calculated would last for about 66 minutes at 15 LPM. I don't think i need to buy the 10 litres one right? The cost isn't much different at all, so should i go for the 10 or stick with the 5?


This is the regulator, flow meter and hose that i've found, would they do the job? Any advice would be greatly appreciated! Thanks a lot

Only issue is he hose may be too heavy.

I purchased a flowmeter regulator in one unit.

Is one of those available to purchase where you are?

Here are photos of a flowmeter regulator for Helium and Argon that is available in the US, along with an adapter to change the output from 5/8 - 18 inert gas hose connection to 1/4" hose barb to connect 1/4" I.D. PVC plastic tubing. Helium and Argon seem to be more available to purchase online than Nitrogen.

I am intentionally not mentioning the brand, etc., and if these photos violate the rules, please remove them. You cannot buy these items at hardware stores or home centers, but a search online will show which welding and tool supply stores sell them. The total cost without tax was about $97. The small round hose clamp on the adapter kit is not used with PVC tubing so can be discarded.

I would never encourage anyone to take their life, especially someone young, or who was in good physical health and free of pain and disease. Your life matters! Fight for yourself with all your strength! But for anyone that has made the decision to end their life by means that are unreliable and so could possibly leave them alive but severely injured, or violent, frightening, painful, illegal, etc., perhaps this information will allow you to consider using this method instead and prevent some suffering.

i found these, i think they're pretty much the same. Would they do?
Thanks a lot

 

[WearyOfStruggling]

Yes, I think so.

I thought so too.. how's this one? I also have long hair and my plan was secure the end of the hose with an elastic (or scrunchie) so it would would be at the back of my head. Would that be ok to do? I'm worried the elastic band would interfere..
thanks a lot

You don't need an inert gas hose, just buy some PVC plastic tubing from a hardware store and slip it over the hose barb output on the flowmeter regulator. In the US, the correct size tubing is 1/4" I.D.

I found something very similar on the same website, but doesn't it need those bolt looking things (not sure what they're called..) at the end to make sure its secure?

 

[Aap]

If it fits properly, then no, but you can find something like this if concernened. Clear tubing is what you are looking for, preferably a smaller nozzle diameter than the flow meter you found.

These are much better. You can use IV tubing.

Thanks! I can't seem to find the diameter of the nozzle for the flow meter, but this it the hose that i found. It says 7 Bar Max pressure in the description, i have no idea what that means, would it be ok? ( sorry for being a bit extra with sending so many photos )

 

[Aap]

From your second round of pictures, that looks like a 1/4" diameter nozzle. IV tubing will almost definitely work.

5 l 200 bar are more than enough. Big difference in size and weight to 10 l.

 

[FreddieQuell]

I'll try and answer some of your questions as best I can:

- 5 L at 200 bar would give you an approximate 5*200 = 1000 liters of unpressurised gas. With a flow rate of 15L per minute you would have 1000 / 15 = 66.67 mins of gas flow. Peaceful Pill handbook advises a 25 mins of gas flow, which would make a 5L cylinder at 200 bar more than enough

- A regulator lowers the pressure - the gas in your cylinder is highly pressurised and just opening it without a regulator would be a bad idea. Your regulator gauge indicates the pressure of your cylinder - when connecting, check if it is at 200 bar as it should be (in the case of a full cylinder)

- A flow meter allows you to control the flow of gas from your cylinder in liters per minute so you can more accurately control the flow of gas, Peaceful Pill handbook advises a flow of 15L/min for our purposes

- I'd advise you to purchase a combined regulator and flow meter as in your second post with pictures - less parts, less chance of wrong connections

- Please check the valve connection on your cylinder to know what regulator w/ flow meter you need.

- For the hose a PVC hose would be preferable to an inert gas hose: it's more flexible, lighter and if you have the right diameter just as good / airtight. I personally use a silicone hose that is even more flexible and can be stretched out to fit the exit valve using a bit of hot water to soften it up

- Your gas will be exiting your cylinder at 1 bar (normal atmospheric pressure) so you don't need to be concerned about the pressure your hose can take - the inert gas hoses you posted are designed to handle high pressure which we don't need in our case

No, those "bolt looking things" are inert gas fittings which won't connect to the output hose barb on the regulator flowmeters in the pics in your second post. The PVC plastic tubing I mentioned just slips over the hose barb without a fitting. You can use the hose clamp @Aap showed, but if the tubing size is correct, it is really unnecessary. I suggest when you have the regulator flowmeter, take it to a hardware store and select the tubing that fits. That's what I did.

It's important to use tubing that is soft enough to be held against the neck with the elastic cord of the bag. Even if the inert gas hose could be connected to the regulator flowmeter, it's much too stiff.

Thank you so much for replying and being so detailed!

these are the data for my cylinder


should i be looking at the outlet valve?


this is the description for the combined regulator and flow meter, i'm so confused. what numbers should i be comparing exactly?


-As for the hose, since would a silicon hose of diameter of 3/8" work fine (since from the description i think it says the valve is 5/8" )

-With the flow meter and regulator, am i only supposed to set the flow meter to 15 and nothing else? What should the reading on the regulators be? And sorry if this is a dumb question but how will i know the gas will be exiting the cylinder at 1 bar?



Thanks again

Does anyone know how to use a supplied air ppe system with hood...peacefully pill have a video apparently.

I have my set up with an exit bag but the advantage of this method would be that you can already be wearing the hood and not have to pull it down.

 

[LotusFlower0369]

Is a flow meter necessary for argon or helium?

did you manage to find a hood. <ake 10 posts and then you can DM
