This is a bottle of reference steel from the US National Institute of Standards and Technology (NIST). These are used to calibrate and test methods of determining steel composition. The picture is a generic bottle with the specific item number smudged out. The particular NIST material number is listed in the title. You may search for specific information about this material, including detailed composition, at http://ts.nist.gov/MeasurementServices/ReferenceMaterials/232.cfm This bottle appears to be about 60% full (new bottles from the NIST, typically containing 150 g of steel, appear to be 50-75% full) Included is the NIST material certificate. Reference material ordered directly from NIST typically cost $200 - $250 per bottle. (this posting is the responsibility of the poster) |
