STANDARD OPERATING PROCEDURE

unknown melting points, the temperature should only be gradually raised, , a few degrees per minute. For samples whose melting points are essentially known, you can quickly raise the temperature to about 20° less than the expected MP. Then raise the bath temperature slowly. Consult the Owner's Manual for more information. 6.

Melting point Wikipedia

The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
