NMR tube
An NMR tube is a tube used in NMR Spectroscopy (used to detect molecule structures depending on peaks on a graph). Cleaning it usually uses acetone or dichloromethane and getting rid of it involves vacuum and maybe IR lamp. Organic chemists sometimes send samples to an NMR lab to get it back with the graph and detect if they got their product.
