Fully automatic measurements

The M5000 provides fast, easy and automatic examination of powdery substances with a melting point up to 400 °C. Due to the automatic determination of the melting point, an objective measurement result is always guaranteed. The high preheating rate and the integrated fan cooling allow fast and reliable measurements in any temperature range. The display provides a well-arranged readout of all important measuring data.

Applications

Typical applications

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.

The advantages of automatic and semi-automatic measurement

The determination of melting point is a fundamental technique in sample analysis, yielding essential information on material composition and purity. It is also a technique which it is possible to complete, without specialist equipment.

Why then, should one invest in an automated melting point meter? While it is possible to manually heat a sample and observe it, perhaps through a microscope, to determine melting point, this is a cumbersome and unreliable approach. The modern melting point meter is faster and more accurate, providing reproducible results which do not rely on the skill of the individual operator and which can be printed for a permanent record. Digital control means that the sample is heated, the melting point recorded, and the apparatus cooled ready for the next sample is just a few minutes, without operator intervention. Sample sizes are small, being just enough powdered material to fill a small capillary tube, and the output reading is accurate to within 0.3 – 0.5C with good reproducibility.
