Melting Range Apparatus (MEPA) is the most advanced microcontroller based apparatus that has been designed with the user friendly and latest design standards. The system comprises of options including Alphanumeric Sample Name, Identification Number, Sample Number as well as Date of authentication along with the complete evidence of foolproof and GLP complaint. Moreover, it operates with the functionality of two different operating modes such as Pharma mode and Thermo mode. Here, Pharma mode automatically detects melting point with photo sensing and temperature is administrated with respect to pharmacopoeia. In Thermo mode, melting point is also detected in the same pattern except the temperature is displayed by providing correction related to the heating rate based on Thermodynamic evaluation.
