KRÜSS - Model M3000 -Melting Point Meter for Semi-Automatic Measurements
The M3000 provides fast and easy examination of powdery substances with a melting point up to 360 °C. Due to the triple capillary intake, it is possible to analyse three samples within one measurement run. Thanks to the preheating rate and the integrated fan cooling, fast measurements are possible in any temperature range. The display provides a wellarranged readout of all important measuring data.

The determination of the melting point is of great importance in the identity test, since many substances can be determined by their melting point.
The purity of substances can also be qualitatively measured via melting point. A well-defined melting point is only given for 100 percent pure substances. Due to impurities, such as impurities or dopants, most substances have a melting interval (beginning of the melt to completion of the melt) of a few degrees Celsius. Even impurities during the manufacture of chemicals cause this melting point to expand to a melting interval. As a result, most substances that are examined with a melting point meter have a melting interval. This effect is used to identify the degree of impurity of the substance.
