How Are The Instruments And Equipment inside The Glove Box Placed

Glove box, also known as inert gas protection box, is a device used for experimental operations in an anhydrous and oxygen free environment. It is widely used in fields such as chemistry, materials science, semiconductor manufacturing, etc. to ensure that sensitive materials and reactions are not affected by atmospheric moisture and oxygen. So how are the instruments and equipment required for the experiment placed in the glove box?

The most common method for transferring small experimental instruments and equipment is through the transition compartment of the glove box. The transition chamber is a small isolation room that allows items to be safely transferred from the external environment to the inside of the glove box without directly opening the main box.

Place the instrument or equipment into the transition chamber, close the transition chamber door, evacuate and fill with inert gas to ensure that the environment inside the transition chamber is consistent with that inside the glove box.

Open the inner compartment door between the transition chamber and the main box, and transfer the instruments or equipment to the inside of the glove box through the inner compartment door.

After completing the transfer, close the transition compartment door and perform appropriate gas replacement on the glove box to maintain the stability of the internal environment.

2. Placement of large experimental instruments and equipment

For large equipment that requires replacement or removal of glove boxes in the later stage, it may be considered to customize a larger transition compartment. The transition compartment is a passage that connects the outside and inside of the glove box, allowing for a safe transfer of equipment without damaging the internal environment of the glove box.

For some large equipment that can be modularized and split into multiple parts, it is possible to consider splitting them and placing them one by one into the glove box through the glove box transition compartment, and then reassembling them inside the box.

If large equipment needs to be placed inside the glove box, the method of dismantling the window can be considered, which allows the equipment to be directly placed inside the glove box. But it is recommended to minimize the frequency of dismantling windows as frequent dismantling may affect the sealing performance of the glove box, and it is not recommended to dismantle windows during the experiment, as this will have a destructive impact on the atmosphere inside the glove box.

Operation steps: When disassembling the window, it is necessary to use appropriate tools and ensure that the sealing of the glove box is not damaged during the operation. Carefully place the instrument or equipment into the glove box, ensuring not to touch the inner walls or other sensitive parts of the glove box.

Install back into the window and check the sealing of the glove box to ensure there is no gas leakage. It is recommended that professional personnel carry out the disassembly and installation of the window to ensure the correctness and safety of the operation.

The most ideal placement strategy for large equipment is to pre position the equipment inside the glove box during installation. This can avoid opening and closing windows in the later stage and reduce the impact on the sealing of the glove box.

Cleanliness: Before placing any instruments or equipment into the glove box, ensure that they are clean to avoid contaminating the internal environment of the glove box.

Compatibility: Ensure that the materials of instruments and equipment are compatible with the internal environment of the glove box, avoiding chemical reactions or corrosion.

Accurate placement: When placing instruments and equipment, ensure that they do not interfere with other devices or operations inside the glove box.
