General description

Mettler-Toledo calibration substance ME 51143095, potassium nitrate is provided with the melting point specific to Mettler-Toledo instrument, documented under both thermodynamic mode and pharmacopeia modes.
The melting point value equals a mean of 6 to 12 measurements with a Mettler-Toledo MP70 Excellence instrument that is calibrated with primary standards. The mp value is found using Capillary method, in accordance with European Pharmacopeia (2.2.14.)

Application

Potassium nitrate, Mettler-Toledo calibration substance ME 51143095 is used as a melting point calibration standard to assess the performance of Mettler-Toledo melting point instruments.

Features and Benefits

  • Melting point traceable to a primary standard (LGC, London)
  • Physically correct and heating rate dependent melting point evaluations using thermodynamic and pharmacopeia modes of testing, respectively
  • Certificates of analysis and safety data sheet provided
  • Uncertainty of measurement up to ± 0.5 °C
