Operating a Chemical Melting Point Tester:

Preparation:

  • Ensure the tester is clean and free from contaminants.
  • Set up the apparatus in a controlled environment.

Sample Loading:

  • Place a small amount of the substance on the sample holder.
  • Use a spatula for uniform distribution.

Temperature Programming:

  • Input the desired temperature range for the test.
  • Gradually increase the temperature, observing the sample.

Observation:

  • Monitor the sample for any changes, such as melting or decomposition.
  • Record the temperature at which these changes occur.

 

Maintenance of the Chemical Melting Point Tester:

Regular Cleaning:

  • Clean the sample holder and chamber after each use.
  • Remove any residue or contaminants to ensure accurate results.

Calibration Checks:

  • Perform regular calibration checks using certified standards.
  • Adjust the GAO Tek’s instrument if there are any deviations from the standard values.

Temperature Sensor Verification:

  • Verify the accuracy of the temperature sensor periodically.
  • Calibrate or replace the sensor if necessary.

 

Calibration of a Chemical Melting Point tester:

Standard Substance Selection:

  • Choose a substance with a well-defined melting point as a calibration standard.

Temperature Calibration:

  • Heat the calibration standard and record the observed melting point.
  • Adjust the GAO Tek’s instrument’s temperature settings to match the known value.

Verification:

  • Test the calibration standard periodically to ensure ongoing accuracy.
  • Adjust as needed to maintain precision.
