Description
- General description: Melting point standard 235-237 °C, caffeine is useful to calibrate melting point instruments, in the thermodynamic mode of measurement. The value of its melting point is determined with an average of 6 to 12 measurements using a Büchi B-545 instrument that is calibrated against primary standards.
- Application: Caffeine melting point standard 235-237 °C finds its use in the characterization of pure chemicals and pharmaceutical compounds.
- Features and Benefits: Melting point calibration standard traceable to primary standards (LGC, London) Grade: Analytical Standard Standard deviation up to ± 0.3 °C Provided with certificates of analysis and safety data sheet
