I've actually just upgraded my system, I purchased a couple CO2 bottles on Craig's List. Apparently these are used for pop machines and grow operations. I bought two tanks for $125. Then I bought a regulator, both tanks came full of CO2 and were filled to 800 PSI. I bleed off the CO2 from the tank at a pressure of just under 5 PSI. So far I've been gassing using the same tank for a couple months (multiple times every five days for 20 seconds per event) and the 800 PSI is still showing, I'm guessing I could probably go a whole year or more on one tank. And the guy that sold them to me said he fills them at a grow shop for $8. I think this is the most economical in the long run.
To connect to my 'gas chamber' I use a flexible braided hose connected to a tire valve stem. I removed the core of the valve stem and simply plug the hose right on. I add rodents, cover the chamber with a towel, keep the tank in the basement by the door but put the chamber outside with the sliding door mostly closed, then gas for 20 seconds. I try to keep all of the gas outside of the house. Then I bring the chamber inside, close the door, and put it on a chair for two minutes. I'm finding that if I gas a lot of rodents they start to cool off before I feed them all, so I pop them in an incubator at 110F and pull them out one by one. I also put a paper towel in the chamber because they almost always pee. I really like the little on / off valve that comes with my regulator. That's what I use to turn the gas on and off. If I get an abundance of rats that are just the right size to feed I'll gas them and freeze them. I found that freezing them on a platter in a zip lock bag overnight and then vacuum sealing them the following day works the best. And they all come apart easy when I break the seal on the vacuum sealed bag (don't vacuum seal unless they are frozen!)

Definitely more economical in the long run - I know you breed your own rodents and have a lot of snakes.
I'm your setup, is there a pressure relief somewhere in the plastic container?
