During the holiday, the glove box in university laboratories will not be used for a long time. As an important experimental protective equipment in the laboratory, the glove box often stores sensitive materials and precision instruments that need to be maintained in a specific environment. How can we ensure that these valuable laboratory items and glove box equipment are properly managed during holidays? How can we ensure that the laboratory glove box remains in good condition during holidays and operates stably after holidays? Here are some operational suggestions on how to manage glove boxes during holidays:
If the glove box is not used for a period of time, it is not recommended to close it directly. Some adjustments can be made to maintain a stable atmosphere inside the glove box and not affect the experimental items and equipment.
Before the holiday, replace a full bottle of working gas to prevent gas depletion during the holiday period. At the same time, pressure and leak detection should be carried out on the glove box and work pipelines. Once a leak is found, immediately contact the after-sales engineer to ensure that the gas supply is not affected during the holiday period.
Vacuumizing the transition compartment of the glove box can be a preventive measure to avoid potential air leakage problems caused by the compartment lid not being tightly closed.
Adjust the pressure of the glove box according to the laboratory temperature to avoid thermal expansion and contraction. If the laboratory temperature is low and the lower pressure inside the glove box is set high, it will consume more working gas. Specific settings can be consulted with glove box suppliers.
It is recommended to open the circulation system of the glove box normally during the holiday period to ensure a stable atmosphere and environment inside the glove box.
Ensure that all solvents inside the glove box are sealed to prevent evaporation from affecting the performance of the glove box. For precious and active metals, it is recommended to seal and store them before holidays to avoid circulation stoppage caused by insufficient working gas, which may damage the sample due to rising water and oxygen.
Check if the vacuum pump oil is clean and replace it if necessary to maintain the good operating condition of the vacuum pump.
During holidays, if the analyzer and other equipment in the glove box are not in use, it is recommended to turn them off to save energy and reduce equipment loss.
Although the electrical and gas equipment inside and outside the glove box should be powered off before leaving, the main switch of the glove box should not be powered off to ensure that the glove box can still maintain its internal environment during holidays.
Through the above preparation measures, it can be ensured that the glove box in the laboratory is properly protected during the holiday period and welcomes scientific research work in the best condition after the holiday ends. This not only helps to extend the service life of the glove box, but also ensures the continuity and stability of the experiment.
