Application

Ethanol-water solution standard reference material (SRM) is primarily intended for calibrating instruments and techniques used in determining ethanol concentrations in water-based media.

Features and Benefits

  • Available with a certificate documenting NIST-certified mass fraction value of Ethanol.
  • The certified value is obtained from the gravimetric preparation of the solution and from the analytical results determined using gas chromatography.
  • The certified value is metrologically traceable to the SI unit of mass, expressed as a percent.
  • The NIST certificate is provided with expiration certificate, storage, handling,use, and maintenance instructions.
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.

General description

SRM 2900 comprises five 10 milliliter ampoules, each containing approximately 10 mL of solution at an expected concentration of 95.6% by mass.
