3D3DWinekeeper tank.
This is a tank used in a system that lets you preserve wine by purging the bottle with nitrogen. Somehow I'm not surprised it's ended up on eBay: Isn't it a lot easier to just drink the bottle?

What's really amazing about this sample is its incredible perfect purity. As you can clearly see from the label, the manufacturer has achieved absolute 100% purity, a goal that has eluded every other supplier of every known substance. The hyper-pure silicon used in chip making is nothing compared to this stuff!
