Sigma Aldrich Fine Chemicals Biosciences Iron Fe standard solution
This Standard Reference Material (SRM) is intended for use as a primary calibration standard for the quantitative determination of iron. A unit of SRM 3126a consists of five 10 mL sealed borosilicate glass ampoules of an acidified aqueous SOLUTIONon prepared gravimetrically to contain a known mass fraction of iron. The SOLUTIONon contains nitric acid at a volume fraction of approximately 10 % equivalent to an amount-of-substance concentration (molarity) of approximately 1.6 mol/L. For more information please refer to the COA and SDS.SRM 3126a cert SRM 3126a SDS

Electron Microscopy Sciences MXS Calibration Standard Mount Certified For 301BE, Spacing
Certified for 301BE calibration standard.
Electron Microscopy Sciences MXS Calibration Standard MXS 301CE for SEM, Pin 300 nm, 300 nm Spacing
EMS offers a series of calibration standards with one and two dimension calibrated patterns. These standards are created utilizing holographic interference of a particular laser frequency. They are typically accurate to <1% across the entire surface of the standard. These reference standards are remarkably durable under typical operating conditions. The surface contamination behavior is also very good. There are no better sub-micron reference standard available in this price range. For SEM
Mount: Pin
Spacing: 300 nm
Structure: Parallel Ridges
Material: W-coated Photoresist on Si
