DEFINITIONS & ABBREVIATIONS
- Insulated gloves
- Data logger, Escort or equivalent
- Isopropyl alcohol, Merck or equivalent
- Wear insulated gloves during handling of apparatus and materials
- Use tongs for sensitive apparatus
- Never stand in front of an open operating incubator
- Use safety glasses
- Connect to main electricity supply
- Turn on the main switch
- Rotate the control knob to position ‘‘I’’
- Check pilot lights
- Green pilot light indicates “Instrument Is Ready”
- Yellow pilot light indicates “Heating is ON”
- Set the temperature by setting temperature regulator knob to desire temperature between 30°C – 70°C range
- Open the incubator door by pulling the door knob
- Place the apparatus or materials on the shelf adequately separated from one another in the incubator
- Close the incubator door by pushing the door knob
- To switch off the instrument rotate knob to position “O”
- After the work performed, remove the apparatus or material wearing insulated gloves
- Wipe the interior surface of the incubator by using wet duster fortnightly or whenever required in switch off condition
- Note: Prior to perform any activity; disinfect the stainless steel surfaces of the incubator using IPA
- Ensure the incubator is clean and sanitized.
- Verify that the incubator shelves are correctly placed and secure.
- Confirm that there are no signs of wear or damage to the incubator seals.
- Place samples evenly inside the incubator to ensure uniform temperature, CO2, and humidity distribution.
- Do not overcrowd the shelves to allow proper air circulation around samples.
- Regularly monitor the incubator’s temperature, CO2 concentration, and humidity level (if applicable).
- Record these parameters at predetermined intervals in the operation log.
- In case of power failure, refer to the contingency plan for backup power sources and sample protection protocols.
- If there are deviations in temperature, CO2, or humidity beyond acceptable limits, investigate the cause immediately and take corrective actions.
- Record the temperature twice daily for days in use, readings separated by at least 4 hours
- Note down the readings in the form
- Use a calibrated thermometer to measure the incubator’s temperature.
- Compare the measured temperature with the setpoint temperature. c. If there is a deviation beyond an acceptable range (±0.5°C), initiate calibration adjustment following manufacturer guidelines.
- Incubator is calibrated internally after every three months
- Internal calibration
- Upload the data logger for one hour as per SOP for Calibration and Operation of Incubator of Data Logger
- Place the data logger in the incubator for one hour
- After one hour remove the data logger from incubator
- Download down the data logger readings and check any deviation
- Print out the readings
- Perform internal calibration after every three months
- Perform external calibration on annual basis or whenever required
CO2 Calibration (If applicable):
- Use a calibrated gas analyzer to measure the CO2 concentration inside the incubator.
- Compare the measured CO2 concentration with the setpoint value. c. If there is a deviation beyond an acceptable range (±0.1%), initiate calibration adjustment following manufacturer guidelines.
Humidity Calibration (If applicable):
- Use a calibrated hygrometer to measure the humidity level inside the incubator.
- Compare the measured humidity level with the setpoint value. c. If there is a deviation beyond an acceptable range (±2%), initiate calibration adjustment following manufacturer guidelines.
- Do not place apparatus and materials directly on bottom plate of the incubator. This will disturb the performance and furthermore, the internal temperature and will cause malfunctions. Be sure to utilize the shelves provided
- Switch off in case of over temperature
- Put the apparatus and materials on flat surface. If using stand, then make sure that the surface is leveled
- Care must be exercised that no items should be placed directly against any of the heating ribs either to the sides, top or bottom of the incubator
- For wet loads a dry tray should be placed at the bottom
- Reduce the number and lengths of the periods for which the door is opened for the purpose of adding or removing apparatus and materials
- It is advisable to monitor the first 2 – 3 minutes of operation to ensure that the incubator is functioning correctly before leaving it to run without supervision
- When units are used for sterilization, it is important to close the ventilation slide after loading
- Ensure the incubator is clean and free from any debris.
- Verify that the incubator is empty and all samples have been removed.
