Digital Melting Point Apparatus
Product Code : EL-CLE-10994
Quick answer: The Digital Melting Point Apparatus heats two capillary samples at once from ambient to 300 deg C and shows the temperature on a three-digit LED display, while built-in illumination and a magnifying lens give a clear view of the melt. It is used to identify solids and check their purity. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the melting point experiment is done
Melting point is one of the quickest checks on a solid organic compound. A pure substance melts within a narrow range of a degree or two and matches its literature value; an impure or wrong sample melts lower and over a wider range. Mixing an unknown with a known sample and finding no drop in melting point (a mixed melting point) confirms that the two are the same compound.
The apparatus uses two heating rates for this. A fast rate of 20 °C per minute brings the block up to a plateau just below the expected melting point, then a slow rate of 2 °C per minute keeps the sample and the sensor at the same temperature, so the reading taken at the moment of melting is accurate.
- Fill two capillary tubes with 2 to 3 mm of finely powdered, dry sample at the sealed end.
- Insert both tubes into the heating block, where they are lit and seen through the magnifying lens.
- Heat at 20 °C per minute to a plateau a little below the expected melting point.
- Continue at 2 °C per minute and watch both samples through the lens.
- Record the display reading when the first liquid appears and when the last crystal melts.
