Q Can glove boxes with two purification columns perform regeneration operations simultaneously?

A
The two purification columns of the glove box cannot be regenerated simultaneously to prevent system overload or damage. The regeneration process requires specific operating conditions and precautions. If two purification columns are regenerated simultaneously, it may interfere with the smooth progress of the regeneration process and even damage the equipment.

Specifically, the regeneration process requires shutting down the circulation of the corresponding purification column and ensuring sufficient supply of regeneration gas. If two purification columns are regenerated simultaneously, it may lead to insufficient supply of regeneration gas or unexpected interruption of certain steps in the regeneration process, thereby affecting the regeneration effect and equipment performance. In addition, during the regeneration process, the purification column will be in a high temperature state. If two purification columns are regenerated simultaneously, it may increase operational difficulty and safety risks. Therefore, in order to ensure the normal operation of the glove box purification system and extend equipment life, it is recommended to follow the glove box manufacturer's recommendations and operating procedures for regeneration operations to avoid simultaneous regeneration of two purification columns.
Q What are the common glove box maintenance misconceptions that need to be avoided?

A Some common misconceptions during glove box maintenance include using incompatible chemicals, neglecting regular system checks and calibrations, and not conducting sufficient testing to confirm glove box performance after maintenance. In addition, it is also advisable to avoid operating glove boxes without training, and to attempt repairs on one's own without seeking professional assistance when problems arise, as this may result in more serious damage.
Q How to troubleshoot if there are abnormalities in the glove box after replacing components?

A If there are abnormalities in the glove box after replacing components, the first thing to check is whether all components have been correctly installed and sealed during the replacement process. Secondly, check whether the power supply and circuit connections are stable, and whether the control system is working properly. Next, perform a glove box cleaning to ensure that the environment inside the box meets the required standards. If the problem persists, use the monitoring system of the glove box to check the concentration of oxygen and water, and confirm whether the gas purification system is working properly. Record all abnormal situations and contact the manufacturer or technical support of the glove box for further diagnosis and repair.
Q How to determine the service life of the adsorption material inside the glove box purification column?

A The service life of the adsorbent material in the glove box purification column is usually determined based on the degree of decline in its adsorption performance. The effectiveness can be evaluated by regularly monitoring the oxygen and moisture levels inside the glove box. If the level of pollutants inside is found to be abnormally high and the glove box cannot recover its adsorption performance after regeneration, even if the adsorption material has not reached the manufacturer's recommended replacement time, replacement should be considered. In addition, changes in the physical state of the adsorbent material, such as color changes, hardening, or fragmentation, are also signals for replacement. The replacement time provided by manufacturers is usually recommended based on standard usage conditions, and the actual service life may vary depending on frequency of use, operating environment, and maintenance.
Q How to deal with oil leakage at the outlet of vacuum pump？

A When the vacuum pump outlet leaks oil, the vacuum pump should be immediately shut down and the cause of the oil leakage should be checked. Oil leakage may be caused by high oil level, damaged seals, or worn internal components of the pump. According to the severity of the oil leakage, measures such as cleaning the pump body, replacing seals, or adding pump oil can be taken. During the processing, it should be ensured that the vacuum pump is powered off and cooled down to prevent accidental injury. After processing, conduct a leak test to ensure that the issue is properly resolved before putting it back into use.
Q How often is the adsorption material of the purification column in the glove box changed?

A The frequency of replacing the adsorption material of the glove box purification column depends on the regeneration effect of the purification column. Usually, the purification column needs to be regenerated after its adsorption capacity drops to a certain level, which can be determined by regularly monitoring the concentration of oxygen and moisture in the glove box. If the detected concentration approaches or exceeds the preset threshold, even if the usage time is not long, the purification column needs to be regenerated. In addition, if the glove box is frequently used to handle materials with extremely high environmental requirements, or if a large amount of solvents are used during operation, the frequency of purification column regeneration will also be higher. When the purification effect of the glove box cannot be restored through regeneration, it is necessary to replace the adsorption material inside the purification column.
Q What are the common mistakes to avoid when replacing a purification column?

A Some common errors when replacing the purification column of the glove box include: not turning off the glove box power first, not wearing appropriate personal protective equipment, not following the manufacturer's instruction manual, using purification materials that are incompatible with the glove box, not checking whether the new purification column is damaged or damp, and not conducting testing after replacement.
Q What are the recommended glove box brands?

A When choosing a glove box, consideration should be given to its durability, ease of use, maintainability, and cost-effectiveness. Some major brands such as Mikrouna have their own glove box research and development capabilities and production factories, providing customized glove box functions to meet the needs of different research and experimental users. Mikrouna's glove box is typically equipped with an intuitive user interface and a user-friendly manual, making it easy to learn and use. In addition, larger manufacturers like Mikrouna offer comprehensive after-sales service and customer support, ensuring timely assistance in case of any issues during use.
