NIST Standard Reference Database 81 NIST Heat Transmission Properties of Insulating and Building Materials Version 2.0 The NIST Database on Heat Conductivity of Building Materials provides a valuable reference for building designers, material manufacturers, and researchers in the thermal design of building components and equipment.

This Standard Reference Material (SRM) is intended for use in preparing solutions for calibrating electrodes for pH measuring systems at pH values above 11.0. SRM 2193b Calcium Carbonate (CaCO 3) was selected for its low level of alkali metal impurities and prepared to ensure high purity and uniformity.However, this SRM is certified as a pH ONLY

NIST Standard Reference Material (SRM) 3655 helps biopharmaceutical manufacturers perform measurements of glycan molecules in their protein drug products, including the monoclonal antibodies (mAbs

With a pH of 12, Standard Reference Material 2193b is the most basic, or alkaline, of any of the NIST reference materials for calibrating the electrodes used for measurements of pH.

The Standard Reference Materials (SRM) in the 2392 series (2392, 2392-I) are intended to provide quality control when performing the polymerase chain reaction (PCR) and sequencing of human mitochondrial DNA (mtDNA) for forensic identification, medical diagnosis, or mutation detection. This SRM can also be used for quality assurance when

Standard reference materials (SRMs) are relied on by academic, industrial, and government sectors to further research and development, facilitate commerce, and support trade. SRMs are used in a range of fields including environmental analysis, health measurements, industrial materials production and analysis, and general measurements within the
