Instructions for using a sterile sealed container leak detector
Aseptic sealed container leak detector is used to detect whether there is leakage in sealed containers (such as drug packaging, medical device packaging, etc.), ensuring that the packaging container can effectively maintain a sterile environment. The following are the general steps and precautions for using a sterile sealed container leak detector:
1、 Preparation work
Check equipment:
Confirm whether the power supply of the leak detector is connected and whether the operation interface is normal.
Check whether the sensors, pipelines, sealing gaskets, etc. of the equipment are intact to avoid affecting the accuracy of leak detection.
Device settings:
Set appropriate leak detection modes. Different types of containers (such as plastic bottles, glass bottles, infusion bags, etc.) may require different detection modes to be selected.
Configure appropriate detection pressure or vacuum level to ensure testing meets container type and standard requirements.
Cleaning equipment:
Before use, ensure that the detection area of the equipment is clean to avoid any pollutants affecting the detection results.
Prepare the container for testing:
Ensure that there is no obvious damage or contamination on the surface of the container to be tested, and avoid interfering with leak testing.
If it is packaging for drugs or medical devices, ensure that the packaging is not damaged or opened by humans.
2、 Operation steps
Place container:
Place the sterile sealed container to be tested in the testing area of the leak detector. Ensure that the container is placed smoothly and in good contact with the sealing components of the instrument.
Choose the appropriate testing method:
Airtightness test: If using the airtightness test method, leak detection is carried out through the gas set by the equipment (such as air, helium, etc.). Under the set pressure, the sealed container will be placed in the testing chamber to detect any gas leakage.
Immersion method: Some equipment uses immersion method, which involves immersing the container in a water tank and applying pressure to observe whether bubbles appear to determine if there is a leak.
Vacuum detection method: For containers that require airtightness testing, a vacuum environment can be used to detect whether there is gas leakage in the container through negative pressure.
Start testing:
Start the leak detector and begin the testing process. Depending on the degree of automation of the equipment, the detection process can be fully automated or require manual intervention.
The device will provide real-time display or audio signal feedback on the test results. Normally, qualified containers do not display leaks, while unqualified containers will sound an alarm indicating a leak.
View test results:
Check the display screen of the equipment and view the leak detection results of each container. The device usually displays a "qualified" or "unqualified" sign.
The device may also record data such as the time and pressure values of each test for future reference and analysis.
3、 End operation
Remove the container:
After the testing is completed, remove the container and ensure that the leak detection part of the container is not touched during the operation to avoid contamination or damage.
Cleaning equipment:
Clean the working area of the leak detector to ensure that the detection sensors and other key components of the instrument are clean and free of dirt.
Check for any abnormal conditions in the equipment and perform timely maintenance.
4、 Precautions
Equipment calibration
Regularly calibrate the leak detector to ensure testing accuracy and avoid affecting test results due to equipment errors.
Container handling:
During the testing process, avoid touching the sealed part of the container directly with your hands to avoid damaging the sterile environment.
Test conditions:
Set appropriate testing pressure, vacuum degree, temperature and other parameters based on the material and shape of the container to ensure the accuracy of the test.
Regular maintenance:
The leak detector should be regularly maintained after long-term use, cleaning sensors, sealing components, etc., to maintain the normal operation of the equipment.
Safe operation:
During the operation, avoid violent handling and improper contact with the airflow ports and sensors of the equipment to prevent accidental damage.
5、 Common problems and solutions
Leak undetectable: If the device does not display a leak, it may be due to the container not being sealed or a sensor malfunction. It is necessary to check whether the device and container are intact.
False alarm warning: If a false alarm warning occurs, check whether the device is set correctly and confirm whether the container material and shape meet the test parameter requirements.
By standardizing operations and regular maintenance, the use of a sterile sealed container leak detector can effectively ensure the sealing of the container and prevent contamination of the sterile environment.
