Melting point standard 121-123°C, analytical standard 5g

Description

General description
Benzoic acid melting point standard, 121-123 °C is useful as a melting point calibration standard while defining the purity of pharmaceutical chemicals. Its melting point value is determined with an average of 6 to 12 measurements using a Büchi B-545 instrument that is calibrated against primary standards.

Application
Melting point standard 121-123 °C, benzoic acid is an analytical standard used to calibrate melting point instruments, in the thermodynamic mode of operation. It is also used in R & D labs for chemical quality control (QC) and quality assurance (QA) to identify solid crystalline substances and to check their purity.

Features and Benefits
Melting point calibration standard traceable to primary standards (LGC, London)
Grade: Analytical Standard
Uncertainty of measurement up to ± 0.3 °C
Provided with certificates of analysis and safety data sheet
A product of analytical standard grade that meets the QC/QA requirements of melting point analysis
