Application

Ethanol-water solution is intended for use with calibrating instruments and techniques used for the determination of ethanol in blood.

Features and Benefits

  • The certified values for ethanol are provided, that are metrological traceability to the International System of Units (SI) derived unit for mass fraction, expressed as a percentage and determined by gas chromatography with flame ionization detection (GC-FID) and Karl Fischer analysis.
  • Expiration details and instructions for use, storage and handling are provided on the NIST certificate.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Ethanol is environmentally preferable green solvent and thus it aligns with "Safer Solvents and Auxiliaries". Click here for more information.
