  2. WHAT'S MELTING POINT APPARATUS? Melting point apparatus is a tool used to measure the melting point or melting point of a compound
  3. is melting point This apparatus. It has electricity, eyepiece, tube slot, display panel display, heat panel, control knob and extendible feet. plugs connect to electricity. the tube slot contains a capillary tube to test its melting point Component of melting point apparatus
  4. HO W TO U S E MELTING PO IN 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.
