Components of a Melting Point Apparatus

1) Heating Block or Oil Bath

Heats the sample gradually.

2). Capillary Tube Holder

Holds the sample-filled capillary tube.

3). Temperature Sensor (Thermometer or Digital Probe)

Measures temperature accurately.

4). Magnifying Lens (Optional)

Helps observe melting more clearly.

5). Digital or Analog Display

Shows the temperature readings.

How to Use a Melting Point Apparatus

1) Prepare the Sample

Grind the substance into a fine powder.

Pack it into a capillary tube (1-2 mm height).

2) Insert the Capillary Tube into the holder.

3) Set the Temperature

Start with a low heating rate (e.g., 1-2'C per minute).

4) Observe the Melting Process

Record the temperature where the substance starts melting.

Record the temperature where the substance is fully melted.

5) Compare the Results

Check the range (pure substances have a narrow range, while impurities widen it).
