Important Notes for Glovebox Purging

Definition of Purging
Purging involves replacing the air inside the glovebox's main chamber with high-purity inert gas to achieve a low H₂O and O₂ environment. This process is crucial before starting circulation and is typically performed during installation, after opening the window for service, or when handling solvents.

Important Notes

• Set the gas cylinder regulator to 60-80 psi. Insufficient pressure may prevent effective purging.
• If the glovebox contains organic solvents, ensure the exhaust port is properly connected to the facility’s venting system and that it is functioning as expected.
• During standard purging, maintain the glovebox main chamber pressure at approximately 1 mbar (relative pressure).
• If the gas cylinder depletes during purging, first deactivate the "Purging" function on the touchscreen and close the gas cylinder regulator. Ensure the regulator’s secondary gauge reads zero pressure before replacing the cylinder. After replacing, perform a leak test on the gas line to verify there are no leaks, then reactivate the "Purging" function.
• If purging extends beyond the usual time or gas consumption, and moisture or oxygen levels remain outside acceptable limits, recheck for leaks or contact a VTI service engineer for assistance.
