7.What Is the Working Principle of Melting Point Tester?

You will feel confused how to operate melting point tester. The working principle of the melting point tester will endure several stage. Looking at the following workflow, and you will understand it clearly.

Working Principle of Melting Point Tester - Sourced: labster

Step 1: Prepare material

You should prepare the material that you want to test. The material should keep dry, or it will influence the melting result.

Step 2: Put the material into the capillary tube

Capillary tube is a disposable tool. One end of the capillary tube is in a closed state, and the other end is in an open state. You need to load the material through the unsealed end.

Step 3: Turn on the device

After put the material into a new capillary tube, you should insert the capillary tube in the melting point tester and start the device to operate.

Step 4: Record the initial temperature

Once you turn on the device, you should record the initial temperature of the material when it does not melt.

Step 5: Record the result

After a period of time, the material melts gradually. When the solid completely melts, you should record the finial temperature.

8.What Are the Main Methods Used by Melting Point Tester?

Why does melting point tester can detect the melting point? Do you know its methods? The common method used by the melting point tester is the capillary method and microscopic melting point determination method

(1)Capillary method
