During winter vacation, if the school has ongoing long-term experiments or needs to maintain the stability of certain sensitive materials, the glove box may need to operate continuously. If there are no urgent or necessary experiments during the winter vacation, schools may choose to close glove boxes in order to save energy and reduce unnecessary operating costs.
With the arrival of the new semester, the glove boxes in the laboratory will also become busy. A series of inspections and preparations are needed for glove boxes that continue to operate or are closed during the winter vacation to ensure their good performance and provide a reliable environment for experiments and research.
The glove box that continues to operate during the winter vacation needs to undergo the following inspections:
Power inspection: Check whether the power cord of the glove box is damaged, aged, or has poor contact.
Appearance inspection: Firstly, conduct a comprehensive inspection of the exterior of the glove box and the gloves in the glove box to see if there are any signs of collision, scratching, or other physical damage during holiday storage. Special attention should be paid to whether there are dents, deformations, or coating peeling on the surface of the box.
Sealing inspection: Check whether the sealing strips of gloves, doors, and transition compartments are intact, conduct a leak test, and ensure that there is no gas leakage in the glove box.
Gas system inspection: Check whether the gas pipelines, valves, and flow meters are working properly. Check if the air source used in the glove box is sufficient.
Purification system inspection: The gas purification system of the glove box is the key to maintaining a water free and oxygen free environment inside. Check if the filters, adsorbents, and other components of the purification system need to be replaced.
C ontrol system inspection: Check the control system of the glove box and verify that the display screen, operation panel, and other components are functioning properly.
Sensor inspection: Check and calibrate the oxygen analyzer and water analyzer to ensure accurate readings.
Vacuum pump inspection: Check whether the vacuum pump is working properly to ensure the vacuum pumping effect.
To restart the glove box that was closed during the winter vacation, the following steps need to be taken:
Check the exterior of the glove box for damage, inspect the gloves for aging, cracks, or other damages, and replace them with new gloves if necessary.
Clean the exterior of the glove box to remove dust and other potential accumulated pollutants.
Connect the glove box power supply and check if the power cord is damaged, aged, or has poor contact.
Turn on the main power switch of the glove box, open the working gas valve, and conduct a leak test to ensure that there is no gas leakage in the glove box.
Start the analyzer and click on 'Clean'.
After cleaning, when the water oxygen value is below 200PPM, click to start the glove box circulation function to ensure the purity of the internal environment of the glove box.
Organize relevant experimental personnel to receive training on glove box operation procedures, review the correct usage methods, precautions, and emergency response measures for glove boxes.
Through the comprehensive inspection, debugging, and preparation work mentioned above, it can be ensured that the glove box can be safely and reliably put into use after the start of the school year, providing a good working environment for experiments and research. If any problems are encountered during use, it is recommended to contact the manufacturer or professional technicians of the glove box for further inspection and repair.
