No, the 7 lb CO2 cylinder does not have a round bottom. As noted in our response to a competitors erroneous posting our 7 lb cylinder is a reconditioned steel medical oxygen tank with a flat bottom. Steel medical oxygen tanks are in wide circulation and actually have a higher pressure rating than a typical CO2 tank. This means it is actually a stronger higher quality construction than a normal CO2 cylinder. Our 7 lb tank is very competitively priced at $24.95. The main disadvantage to this tank is that it is tall and skinny therefore is not suitable for some spaces. Also because of it's dimensions it should be secured so as to not tip over. If you have any other questions feel free to contact me at 866-496-4983 or

Also keep in mind that all of our reconditioned cylinders are inspected, cleaned, blasted painted, hydro-tested and re-certified by one of the nations largest DOT authorized service centers. Thanks!
