Physical Properties Standards

The measurement of certain physical properties is often used to determine the identity or purity of a substance. To ensure the accuracy of these measurements, the measurement equipment needs to be regularly calibrated using accurate analytical standards with known properties. Sigma-Aldrich offers a wide range of physical property standards for various applications.
  • The products cover a wide range of physical properties, such as, melting point, density, conductivity, viscosity, turbidity, particle size, color, thermal conductivity, mechanical, morphological, optical, and isotope measurement
  • A growing number of products are certified reference materials (CRMs), supplied by recognized accredited manufacturers like Paragon, Whitehouse Scientific, H&D Fitzgerald, and the IRMM
