This document provides information about a melting point apparatus. It is a tool used to measure the melting point or melting range of a compound. It has components like electricity, an eyepiece, tube slot, display panel, heat control knob and extendible feet. To use it, a sample is inserted into a capillary tube and placed in the tube slot. The user turns it on, adjusts the heat, and observes the sample through the eyepiece to determine the melting point range.

T APPARATU S

5. 1.Insert the capillary tube which already contains the fine sample into the tube slot.
Usually the melting tool has a capacity of 3 – 6 tube slots so you can test more than one
sample.
2.Press the ON button to turn on the appliance, adjust the heating level by turning the
heating control knob.
3.Observe the melting point through the eye piece, you can see the sample which can be
enlarged with the eye piece scaler.
4.When the melting point is obtained, the heating temperature is 20°C below the desired
melting point, then slow the heating rate so that the temperature increases no more than
1°C every 30 seconds.
5.Meanwhile, if the melting point is not found, you can heat the sample with a high
heating rate until the substance can melt.
6.Record the first temperature from the melting point range which is indicated by the
presence of the first liquid drop visible through the eye piece.
7.Then record again the second temperature of its melting point range when the sample
melts completely or turns into a liquid.
8.If you want to repeat again with a different sample, you should first remove the first
sample from the capillary tube and allow the tool to cool.
