That is what I do, I bought a canister from a paintball shop near my home and the right attachment to stick a rubber/plastic hose on the end, I drilled a hole into a small (shallow) tub and depending on how many I need to euthanize, change tubs to wider ones. Too tall of a tub would probably use too much CO2, shallow is better IMO. I fill my small canister every 50 or so rats, $4 at the same paintball store.
Hope this helps!

ps- I do this because my first pet was a rat, I now have 35 snakes and I think it is a much less personal way to kill a rat than 'thumping.' Less messy too! I champion PK or FT!
