A vacuum oven is a specialized oven that removes moisture and other gases from a substance by creating a low-pressure environment inside the chamber. This is different from a standard oven, which uses heat and air circulation to dry materials.

• Operate the instrument as per SOP.
  • Set the temperature controller knob to 60°C.
  • After the set temperature is attained, measure it with a calibrated thermometer.
  • The observed temperature should be within ± 2.0°C.
  • Similarly perform the test at 100°C and 150°C and measure the temperature with a calibrated thermometer.
  • The observed temperature should be within ± 2.0°C.
  • Record the readings in vacuum oven calibration record as per Format-I.
  • Create a vacuum of 400 mm and close the valve and observe the Vacuum drop for 3 hours. The Vacuum drop should be not more than 1.0% of the initial Pressure after 3 hours.
  • The frequency for calibration of vacuum oven is Six months.
  • If the calibration is not proper, report the results to the departmental head for taking an appropriate action.
