Looking to get my Calcium reactor online. Seems everything is closed on Saturday, but figured you all would have some interesting sources that I haven't thought of. Thanks.
Cool thanks guys. I realize now that the Airgas on Illinois is about 2-3 blocks from my work. I'll have to set it up during the week. I'll look into Paxair... hadn't heard of it.
Thanks for the info everyone. Sounds like it saved me some time and effort. Ended up going to Redwood city Airgas as Jim suggested. Easy peasy! Thanks!
