FAQ

  • Q How much electricity does a glove box consume per day?

    A Glove boxes provide a stable and clean environment in scientific experiments, and their power consumption is influenced by various factors. Taking a standard single station glove box as an example, the lighting system consumes about 0.1 kWh of electricity, the vacuum pump consumes about 1.5 kWh of electricity, the circulating fan consumes about 0.96 kWh of electricity, and in addition to the power consumption of other equipment such as the control system, the total daily power consumption of a standard single station glove box is about 2 to 3 kWh of electricity. The actual power consumption may vary depending on the brand, scale, supporting facilities, frequency of use, and other factors. Maintaining equipment can help reduce energy consumption and optimize experimental costs.
  • Q What is the function of setting the box pressure for glove boxes?

    A The box pressure of the glove box is a key parameter of the gas pressure inside the glove box, which is crucial for maintaining a specific experimental environment. By setting the box pressure reasonably, samples can be protected from contamination, maintaining stable humidity, and ensuring safe operation. To determine the range of box pressure setting, experimental requirements and equipment manual guidance should be considered, and adjustments should be made through pressure sensors and regulating devices. The box pressure is affected by sealing performance and gas flow rate, and different experiments need to set different box pressures according to their characteristics. Correctly setting the box pressure is crucial for the success of the experiment.
  • Q Where should the glove box be checked for leaks when it is first turned on?

    A
    The first start-up of the glove box requires leak detection of the pressure reducing valve and glove box to ensure the sealing performance of the glove box. Leak detection steps for pressure reducing valve: Open the main valve of the working gas cylinder and adjust the pressure of the auxiliary gauge to between 0.4MP and 0.6MP. (Note: When adjusting the pressure of the secondary gauge with the main valve closed, there is no response from the secondary gauge). Click to set the box pressure to up pressure 4 and down pressure -1, turn off the main valve of the working gas cylinder, and then observe whether the main and auxiliary gauges of the pressure reducing valve drop pressure. If there is no drop pressure, it means that the gas pipeline connection is normal and there is no leakage. Restore the open state of the main valve of the working gas cylinder; Please contact the glove box supplier's technical support for pressure drop.
    Glove box leak detection steps: Click on Settings to set the pressure inside the glove box to up pressure 11 and down pressure 8. Wait for ten minutes, click on record, click on leak rate, the control screen displays a straight line, or the values before and after ten minutes show almost no change, indicating good sealing of the glove box and no leakage.
  • Q Why do we need to clean and cycle the glove box before using it again for the first time?

    A After assembling the glove box at the customer's site, it is usually cleaned first. After the water oxygen value drops to below 200PPM, the cycle is turned on for 2-3 minutes and then turned off, and then the cleaning is continued until the water oxygen value drops below 100PPM. This is because cleaning only replaces the gas inside the glove box, and the gas in the gas pipeline cannot be replaced. It is necessary to rely on circulation to bring the gas inside the pipeline back into the box, and then continue cleaning, trying to consume the water oxygen content inside the glove box as much as possible to achieve complete gas replacement. After the water oxygen value drops to below 100PPM, the glove box regeneration operation can be carried out, which can effectively prolong the use time of the purification column material.
  • Q How to check for leaks in the pressure reducing valve of the glove box? How to check the sealing of gas pipelines?

    A The leakage inspection of the pressure reducing valve in the glove box is to check the sealing of the gas pipeline. With the main power supply of the glove box turned on, open the main valve of the working gas cylinder and adjust the pressure of the auxiliary gauge to between 0.4MP and 0.6MP. Please note that when the main valve is in the closed state and the auxiliary gauge pressure is adjusted, the auxiliary gauge does not respond. Then click the settings button on the PLC control screen to set the upper pressure to 4 and the lower pressure to -1. Then turn off the main valve of the working gas cylinder. After 5 minutes, observe whether the main and auxiliary gauges of the pressure reducing valve have dropped pressure. If there is no drop in pressure, it means that the gas pipeline connection is normal and there is no leakage. At this time, it is necessary to reopen the main valve of the working gas cylinder. If there is any pressure drop phenomenon, immediately contact the technical support of the glove box supplier.
  • Q What things need to be checked before turning on the glove box?

    A
    Before turning on the glove box, a basic inspection is required, as follows:
    1. Check whether the gas is sufficient, whether the working gas pipe is connected to the regeneration gas cylinder, whether the regeneration gas pipe is connected to the regeneration gas cylinder, and whether the working gas pipe and regeneration gas pipe are connected to the glove box.
    2. Are the regeneration exhaust port, cleaning exhaust port, and vacuum pump exhaust port connected to the waste disposal device.
    3. Check if the vacuum pump power supply and oil mist filter are installed properly; Ensure that the oil level is above the minimum and maximum scale lines without excessive pressure; The vacuum pump switch should be in the on state.
    4. Check whether the network cable of the water oxygen analyzer, the power cable of the cleaning valve, the air pipe of the cleaning valve, and the exhaust interface of the cleaning valve are installed correctly.
    5. Check if the accessories such as gloves, shelves, and power cords inside the box have been installed.
    After all the above content is correct, turn on the glove box power.
  • Q Does the size of the transition compartment in the glove box have any impact?

    A The size of the glove box transition compartment has multiple impacts on operation. A larger transition chamber can accommodate larger volumes of items or more samples, which is advantageous when dealing with large objects or conducting batch experiments. Operators can more conveniently place or remove items into or out of the transition warehouse, reducing operational difficulty and time costs. However, larger sizes may also require more space to accommodate the glove box as a whole, and may affect the efficiency of gas circulation and purification inside the glove box, requiring a more powerful circulation purification system to maintain stable environmental conditions. On the contrary, although smaller transition chambers occupy less space, they may limit the size and quantity of operable items. For some large experimental equipment or samples, they may not be able to accommodate them and require more frequent item transfer operations, increasing the complexity of operations and potential pollution risks.
