Laco Technologies sells a line of vacuum degassing systems. They also sell vertical stainless steel chambers and vertical clear chambers separately. They also have some bigger horizontal cylindrical chambers and aluminum box chambers.

That's one possible source of a canned industrial solution, but certainly not the only way to get what you want. It depends a lot on the nature of your requirements - size of what you want to degas, and what sort of visual and mechanical access you might need, for example. It also has a lot to do with your budget and how willing/able you are to hunt, scrounge, improvise, and fabricate.

Care to share any details about the nature of the application?
