How does an automatic melting point meter operate?

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. The low skill levels required mean that the melting point meter can be operated by a lab assistant, or installed outside of the lab for operation by trained personnel in a warehouse or production facility.
