The weird things that NIST (US Government) Sells....
The National Institute of Standards and Technology by the US Department of Commerce is an amazing organization. They help set and maintain standards for nearly everything from the current time to lung power. Honestly, I have no idea what lung powder is. It is probably something you end up with after smoking $240 NIST brand cigarettes. But be careful, that might contaminate SRM 2670a - dried urine. NIST sells Standard Reference Materials. These are things that laboratories can buy to ensure that they have consistent material to work with through their experiments. Want to see some of the weird stuff they sell? Keep reading.
