General information
ROTI®Calipure
The melting point of a substance is the temperature at which the transition from a solid phase to a liquid phase occurs. The determination of melting point is a quick and easy method of determining the basic purity of substances. As the melting point is a characteristic variable for pure substances, it is also used for the identification of organic compounds. Carl ROTH offers a selected range of melting point standards. To allow easy handling and ensure maximum safety, the standards are filled in small quantities protected from light.
Properties:
- Suitable for checking purity
- Max. measurement inaccuracy ±0.3 °C
- Suitable for use independent of instrument type
- Tested according to the european pharmacopoeia method
