Have you tried a grocery store? I'm not familiar with Canadian grocery stores, but I can pick up dry ice, by the pound, at several of my neighborhood grocery stores.

Glad to hear it! I'm glad you're being safe <3.

All of the connectors are the same rating as the main pieces.

Chrys A Lis

This may be a dumb question, but are the connections and seals also rated to take the pressures? You may have parts rated to 3k+ psi, but if the seals aren't up to spec you can still get a critical failure where one part meets another.

Nile Red

I'll post more details when I actually finish. It's kind of a silly project, but it has been really fun to get it all working.

Silviu T

Ooh a tease!

Nile Red

Yeah, that's not a bad idea. I think I'll modify it if I need it in future projects. For now though, its use is very temporary.

Nile Red

It's being done for a very specific purpose. I didnt make it just to have a little co2 canister

Nile Red

I dont plan to hold pressure in here for too long. It's mostly temporary. Also, all the parts are rated for 3k+ psi and I'm never going to be putting it above about 700. Putting a relief valve definitely wouldn't have hurt though

He's doing some extractions with supercritical liquids.

Silviu T

That's easy to do. A few bucks worth of parts from the hardware store. I've done similar things in the past.

Mono Keras

I mean, really? There was no easiest way to this?

Silviu T

You may want to put another valve between the canister and the gauge.

Aaron Aitken

I assume there really isnt any commercial purchasing options for dry ice in eastern Canada?

sharp cut threads are stress raisers i would do a pressure test before loading a working high pressure charge

I'm sure you know what you're doing. My only concern would be, as with all high pressure containers, an emergency pressure relief valve. I know that operating well within design limits is probably fine, but pressure vessels are terrifying.
