• 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

The Automatic Melting Point Apparatus is the latest technology for microprocessor-based determinations of melting point ranges of crystalline, powdered and polymeric materials, and is used to assess sample purity. It requires approximately 5mg of sample spread uniformly on a glass slide, covered with a glass coverslip. The slide is placed on a uniformly heated, round furnace and subjected to a heating profile as required by the user. Precise temperature control gives reproducible results to within 1%. The unit contains an automatic temperature safety cut-off feature if no melting points are detected 15°C above the expected melting point or if the oven reaches 315°C. The melting process is magnified, recorded, and viewed on-screen in real-time by a CCD camera. The change in physical appearance of the sample with respect to temperature is recorded, and the start/end of melting is observed automatically. A representation of the entire process can be printed out in graphical form for validation.
