Automatic Melting Point Range Apparatus

Test Method
The melting point of a crystalline solid is the temperature at which the solid to liquid phase transition occurs, referenced at one atmosphere (1 ATM) of pressure.

Conforms to BP Appendix 5 - Method 6 and GLP specifications

Readily interchanged between automatic and manual detection of melting point ranges

Intelligent Lamp Intensity Control with Soft Start

Storage capacity for up to 20 sample tests

User-interactive software and data entry, including easy alphanumeric entry of sample name, ID number, and date

User selectable operating modes:
AUTO detection mode: Start/end of melting point range is automatically detected by a photosensing infrared device. The melting process is recorded and viewed on-screen in real-time by a CCD camera.

MANUAL detection mode: Start/end of melting point range can be selected manually with a key-press by user. Sample melting point can be determined as per BP method by ‘Heat & Cool’ temperature function. As above, the melting process is recorded and viewed on-screen in real-time by a CCD camera.
