Laughing Gas (N2O) , 99.999%, GB or standard cylinders as the package.

Nitrous oxide, N2O, is a colorless, almost odorless gas, that was first discovered in 1793 by the English scientist and clergyman Joseph Priestley (who was also famous for being the first to isolate other important gases such as oxygen, carbon monoxide, carbon dioxide, ammonia, and sulfur dioxide) . Priestley made N2O by heating ammonium nitrate in the presence of iron filings, and then passing the gas that came off (NO) through water to remove toxic by-products.
Nitrous oxide found a more scientific use as an anesthetic in clinical dentistry and medicine in the early 1840s. The story goes that at that time, a medical school dropout called Gardner Quincy Colton went around the country putting on nitrous oxide exhibitions. In 1844 he happened to put on a demonstration in Hartford, Connecticut, and in the audience that day was a local dentist named Horace Wells. Dr. Wells watched with interest as one of the volunteers, a man named Samuel Cooley, inhaled the gas, and, while still under the effects of the N2O, injured his leg when he staggered into some nearby benches. When he went back to his seat next to Dr. Wells, Cooley appeared to be unaware of the injury until the effects of the gas wore off. Dr. Wells immediately realised that N2O might possess painkilling qualities, and so after the demonstration, Wells approached Colton and invited him to participate in an experiment the next day. Colton agreed, administered nitrous oxide to Dr. Wells while another local dentist extracted one of Wells' molars. Dr. Wells experienced no pain during the procedure, and the birth of N2O as a dental and medical painkiller had arrived.
