FAQ

  • Q Where did the liquid in the glove box come from?

    A There are three main sources of liquid in glove boxes. Firstly, during the experimental process, liquids may be intentionally or unintentionally introduced, such as liquid products produced in chemical reactions or solvents added during the experimental process. Secondly, equipment malfunctions, such as pipeline and valve failures in glove boxes, may cause liquid leaks, such as coolant leaks or condensation in gas pipelines. There is also external pollution, and external liquids may enter the glove box through the sealed area or other means, such as water infiltration or liquids brought in by operators.
  • Q What measures should be taken if using a glove box outdoors?

    A
    If you want to use a glove box outdoors, you need to communicate with the glove box manufacturer and choose a specially designed outdoor glove box with good sealing, protection, and temperature control capabilities; When there is no dedicated glove box for outdoor use, temporary protection such as sunshades and windproof covers can be installed, and insulation materials can be used to wrap and alleviate the impact of temperature changes. When placing, choose a flat, dry, well ventilated place away from dangerous objects, avoiding low-lying areas, air vents, and direct sunlight. Carefully inspect the seal before use, perform regular maintenance, check the condition of components such as purification, gloves, and seals, and replace damaged parts in a timely manner. Clean both inside and outside. Attention should also be paid to safety. Do not use during thunderstorms to prevent the glove box from being blown over or impacted.
  • Q What environmental challenges do glove boxes face when used outdoors?

    A Glove boxes face various environmental challenges when used outdoors. The outdoor temperature difference is large, and high temperatures may cause the temperature inside the glove box to rise, affecting materials and equipment. Low temperatures can easily freeze and damage glove box components; In terms of humidity, the outdoor humidity is high and varies greatly. When the sealing is poor, moisture can damage the low humidity environment inside the glove box; There is a lot of external dust and pollutants, which can contaminate materials and equipment when entering the box; Wind and rain may damage the glove box structure, and rainwater infiltration can cause equipment and circuit failures; In addition, prolonged exposure to sunlight can increase the temperature of the glove box and generate ultraviolet radiation, affecting the material's performance and lifespan.
  • Q How to use leakage method to test the sealing performance of glove box?

    A The leak detection method uses professional equipment such as helium mass spectrometer leak detector or halogen leak detector to test the sealing performance of glove boxes. Firstly, ensure that the glove box is sealed and all interfaces and valves are closed. Then, connect the leak detection device to the glove box according to the device instructions and select the appropriate detection pressure (positive or negative). After starting the device, if there is a leak, the detection instrument will display the location and size of the leak. At this time, it is necessary to check the installation or replacement of the sealing material; If no leakage is detected, the sealing performance can be confirmed as good.
  • Q What is the main function of the gas cylinder in the glove box?

    A The gas cylinder in the glove box is mainly used to provide high-purity inert gases for filling into the glove box. These inert gases include nitrogen (N ₂), argon (Ar), hydrogen (H ₂), etc. They have stable chemical properties and are not easily reactive with other substances. In addition, glove boxes may also support the use of rare gases such as helium (He), neon (Ne), etc., which have unique physical properties under specific conditions and are therefore used in certain scientific research and production fields. In general, gas cylinders provide the necessary gas environment for glove boxes to meet the needs of different experiments and production, ensuring the accuracy of experiments and the safety of materials.
  • Q How to determine the sealing performance of glove box sealing materials by inspecting their appearance?

    A The appearance inspection method evaluates the performance of sealing materials by directly observing their appearance. Check whether the sealing material is flat and smooth, whether there are cracks, bubbles, deformations, etc., and pay attention to whether the color is uniform, whether there are signs of discoloration or aging. If the appearance of the sealing material is good and there are no obvious problems, it may indicate good sealing performance; If there are any issues, further inspection of the sealing performance or replacement of the sealing material is required.
  • Q There are experimental materials in the glove box, what should be noted when cleaning?

    A
    During the cleaning process of the glove box, two preparations need to be made before cleaning to avoid damage to the experimental materials inside the glove box. Firstly, it is necessary to fully understand the properties of the experimental materials inside the box, clarify the sensitivity of the materials to factors such as water, oxygen, organic solvents, and temperature, in order to develop more accurate cleaning plans based on the characteristics of the materials. Secondly, it is necessary to properly store experimental materials, carefully transfer them to safe containers or areas for temporary storage, and ensure stable environmental conditions in the storage area to avoid factors such as temperature fluctuations and direct sunlight that may cause damage to the materials.
  • Q How to test the sealing of glove boxes using pressure testing method?

    A The specific operation of the pressure testing method includes sealing the glove box and filling it with a certain pressure of gas, such as nitrogen or air. After selecting the appropriate pressure value, turn off the pressure pump or valve and start timing. Monitor the pressure changes inside the box using a pressure gauge within a set time period (e.g. 1 hour or 24 hours). If the pressure drop is within the allowable range, it is considered that the sealing performance is good; If the pressure drops significantly, it indicates a leak and the installation or replacement of the sealing material needs to be checked.
