I'm looking for a specific piece of glassware to function as a hot water humidification chamber for a science project. I got the idea from the basic condensor used in my organic chemistry lab. Basically I need that without the seperate chamber, just a tube with two axial holes for air and two radial holes for hot water. Does anybody know what this is called or where I might be able to find one? It needs to be as small as possible.for my purposes. Thank you
