Bubbling gas through a liquid

Hello,

My first post - apologies if this is in the wrong place.

I'm attempting to find the best way to bubbling a continues supply of gas through a fixed amount of liquid.

So far, I'm down to two options (see attached picture uploads).

Can you think of anything else that I haven't thought of?

Although slightly more costly, I see the Deschel Bottle as the better option.

Option 1)

Option 2)

Thanks

It depend on the gas and the liquid. If you say ammonia and water a set-up like you showed will not work.

Not too shabby for a first post. Welcome to ScienceMadness!

May I suggest using the <a href="search.php">search</a> function or <a href="http://lmgtfy.com/?q=gas+bubbler+site%3Asciencemadness.org" target="_blank">Google</a> before starting a new thread, however?

There is also a newly minted <a href="viewthread.php?tid=19143">guideline</a> post by Nicodem that you may wish to read.

What are your gas and liquid phases? Knowing the behavior of this system is vital for choosing the correct apparatus. For example, with HCl or NH<sub>3</sub>, an inverted funnel works well but use of a fritted bubbler could be catastrophic.

Finally, I've never heard of ArN<sub>2</sub>. Is it a mixture of Ar and N<sub>2</sub> or does it stand for Analytical Reagent N<sub>2</sub>?
