Glove box is a laboratory equipment used to provide an anhydrous and anaerobic environment, which can be applied in fields such as chemistry and materials science. The purification column is a key component in the glove box, used to adsorb water and oxygen inside the glove box and maintain a high-purity environment inside the box. As the usage time increases, the adsorption material of the purification column will gradually become saturated, and regular glove box regeneration is needed to restore the activity of the adsorption material in the glove box purification column. If the glove box regeneration cannot restore the activity of the adsorption material, the adsorption material needs to be replaced to ensure the normal operation of the glove box purification column.
When replacing the adsorbent material in the glove box purification column, it is necessary to check whether the sealing of the glove box purification column is intact. If the sealing of the glove box purification column is not qualified, the entire purification column needs to be replaced to achieve the function of adsorbing water and oxygen under sealed conditions. Let's take a look at the replacement process of the glove box purification column together.
Replace the adsorbent material inside the glove box purification column
Prepare new adsorption materials: purchase adsorption materials that match the glove box model, such as molecular sieve materials for water removal, copper catalyst materials for oxygen removal, etc.
Disassemble the purification column: Follow the maintenance manual of the glove box to disassemble the purification column.
Replace adsorbent material: Remove the old adsorbent material and replace it with a new one.
Reassemble: Reassemble the purification column and ensure that the sealing ring is installed properly.
Check the replacement effect: Connect the power supply, conduct a sealing test and water oxygen probe detection to ensure that the replaced purification column is working properly.
Replace the glove box purification column
Disconnect the power supply: Before starting the replacement, disconnect the power supply of the glove box.
Disassemble the purification column: Follow the maintenance manual of the glove box to disassemble the purification column.
Install new purification column: Place the new purification column containing adsorbent material in the designated position and ensure that the sealing ring is installed in place.
Check installation: Reconnect the power supply of the glove box, perform a sealing test and water oxygen probe detection to ensure that the new purification column is working properly.
Matters needing attention
When replacing the adsorption material of the glove box purification column and replacing the glove box purification column, the glove box power, gas source and other systems should be turned off to maintain consistent pressure inside and outside the glove box.
Before replacing materials, ensure that the water oxygen probe can accurately detect the water oxygen content inside the glove box to ensure that the adsorption effect can be correctly detected after replacing the purification column and adsorption material.
Using appropriate tools, carefully disassemble the old purification column according to the structure of the glove box and the installation method of the purification column to avoid damaging other components of the glove box.
The old purification tower and adsorption materials removed from the glove box should be properly packaged, processed, or recycled according to laboratory regulations. It is strictly prohibited to store it in containers made of flammable and melting materials.It is strictly prohibited to store them in containers made of flammable and melting materials.
Safe operation: When replacing the purification column, be sure to follow the use and maintenance manual of the glove box to ensure safe operation.
Through the above steps, you can smoothly replace the adsorption material of the glove box purification column or replace the entire glove box purification column to maintain the efficient operation of the glove box. Remember to follow safety regulations during the operation to ensure the smooth progress of the experiment.
