Q What are the operating procedures for using laboratory glove boxes？

A
When using a laboratory glove box, the following operating procedures should be noted:

1. When placing items, try to avoid collisions with gloves and the walls of the glove box to prevent damage to the gloves or affect the stability of the atmosphere inside the glove box;

2. When taking out items, the action should be gentle and slow to prevent contamination caused by the substances in the glove box;

3. When operating inside the glove box, follow the correct sequence and method of operation, and avoid pulling the gloves too hard to prevent them from breaking;

4. Be careful and cautious when using tools to prevent damage to the components inside the glove box.

5. At the same time, pay attention to monitoring the gas pressure and composition inside the glove box.
Q What preparations should be made before operating the experimental glove box？

A
Before operating the experimental glove box, the following preparations need to be made:

1. Be sure to check whether the gloves are intact, without any signs of breakage, perforation, or aging;

2. Confirm that the gas purification system and circulation system inside the glove box are operating normally, and ensure that the atmosphere inside the glove box meets the experimental requirements. For example, if an experiment requires an anaerobic environment, it is necessary to check the measurement accuracy of the oxygen analyzer before use, check the specific oxygen value detected, and ensure that it is within the specified range required for the experiment.
Q Why is lead glass used for the nuclear glove box window？

A
Lead glass plays a significant role in isolation glove boxes in the nuclear industry：

1. Having good visibility, operators can clearly observe the situation inside the glove box through lead glass, ensuring the accuracy of operations during nuclear material sorting, processing, or experimentation.

2. Lead glass can effectively block radioactive rays and provide strong radiation protection for operators, like a sturdy barrier, ensuring the safety of operators.
Q What are the precautions when operating a glove box？

A
When operating the glove box, the following precautions should be taken:

1. Prepare all necessary items and equipment before the experiment, arrange the transfer sequence, and minimize the number of times the transition chamber is used;

2. Wear three layers of gloves, lab coat, and goggles during the experiment, and handle with caution to avoid solvent spillage or instrument breakage;

3. Try to minimize the exposure time of experimental materials and reduce solvent evaporation;

4. After the experiment is completed, properly place the used items and equipment, clean up and report any abnormal situations in a timely manner.
Q Can hand cream be used during glove box operation?

A It is not recommended to use hand cream when operating in glove boxes. Because hand cream may make gloves greasy or slippery, affecting the accuracy and flexibility of operation, and may also contaminate the experimental environment or samples, affecting the experimental results. If hand protection is required, hands should be cleaned and removed from the laboratory environment after the experiment before using hand cream.
Q What type of sensor is the glove box oxygen analyzer?

A The sensors used to detect oxygen content in glove boxes mainly include electrochemical fuel cells and zirconia. The advantages of electrochemical fuel cells are accurate zero point, low drift, strong resistance to the influence of organic solvents, and low replacement costs. But its disadvantage is that prolonged exposure to high concentrations of oxygen can affect its lifespan, and it cannot be used to detect environments containing acidic gases and strongly oxidizing gases. The advantage of zirconia sensors is that they have a fast response time, can be used to detect high-temperature gases, and can be stored in air, making them easy to use. But its disadvantage is that it is not suitable for detecting gases containing organic solvents, and the zero point is prone to drift.
Q What is the role of the glove box evaporation film coating all-in-one machine in solar cell production?

A The glove box evaporation film coating all-in-one machine is integrated with a vacuum coating system and a glove box system. Thin film evaporation is completed in a high vacuum evaporation chamber, and samples are stored, prepared, and tested after evaporation in a high-purity inert gas atmosphere in a glove box. For example, by spin coating perovskite precursor solution in a nitrogen environment of a glove box, avoiding contact with water and air, the prepared perovskite cells can be directly transferred to the evaporation electrode in the evaporation chamber through a connected storage compartment. The entire experiment can be operated in an anhydrous and oxygen free environment, effectively avoiding problems such as component color difference and hot spot effect caused by uneven coating, thereby improving the performance and durability of solar cells.
Q Why is a glove box needed in metal 3D printing？

A The use of glove boxes in metal 3D printing is mainly due to safety and process requirements. From a safety perspective, important materials for metal 3D printing, such as titanium and aluminum, are reactive metals that are flammable and burn quickly, producing extremely high temperatures and pressures. The small particle size of metal powder can be inhaled into the human body, posing a health hazard to operators. The glove box can provide a fully enclosed operating space, minimizing dust exposure and hazards to the greatest extent possible. In terms of process requirements, for example, titanium alloy is a poor conductor of heat, which is prone to heat accumulation during processing. Traditional machining is difficult and has a low yield rate. However, glove boxes can provide a specific inert gas atmosphere environment to meet the environmental requirements of titanium alloy 3D printing, which helps to improve the quality and performance of printed products, such as solving the problem of oxygen embrittlement of titanium alloy in 3D printing.
