Glovebox Gas Cylinder Replacement: Safety Precautions and Steps

Precautions for Replacing Glovebox Gas Cylinders

1.Before replacing the cylinder:

• Ensure that both the primary and secondary pressure gauges of the current cylinder read zero.
• Turn off the circulation and set the lower pressure to -9 mbar.

2.During cylinder replacement:

• Only disconnect the nut between the pressure regulator and the gas cylinder; do not disassemble other components.
• Connect the new cylinder properly at the nut connection and ensure it is well sealed.

3.After replacing the cylinder:

• Adjust the chamber pressure back to the normal range (recommended: 1–6 mbar).
• Perform a thorough leak check on the gas line to ensure there are no leaks.

4.Additional precautions:

• Strictly follow the safety guidelines for handling high-pressure gas cylinders to ensure safe operation.
