This glove box maintains an anhydrous oxygen-free environment with water and oxygen levels below 1 ppm. The equipment includes pressure protection limits of ±15 mbar and uses automated purge and regeneration systems.

• Inert Gas Purity Requirement: The system requires a 99.999% pure inert gas source to achieve sub-1 ppm water and oxygen levels.
• Pressure Safety Limits: The chamber pressure must be maintained within ±15 mbar to prevent automatic protection activation.
• Regeneration Gas Hazard: Regeneration requires a gas mixture containing 5–10 vol% hydrogen, which is flammable and must be handled with proper ventilation.
• Material Compatibility: Butyl rubber gloves and 304 stainless steel surfaces are used; solvents or chemicals that degrade these materials should be avoided.
• Maintenance of Purification Capacity: The copper catalyst and molecular sieve in the purification column have finite capacity (oxygen 60 L, water 2 kg) and require periodic regeneration.

This procedure outlines the steps to start up and safely operate the opposite 4-station glove box. All actions rely on the PLC automatic control and integrated sensors.

Required Equipment: Vacuum pump, Touchscreen PLC controller

1. Connect inert gas supply
   Connect the inert gas (N₂, Ar, or He) at 99.999% purity to the gas inlet and verify the supply pressure.
2. Set chamber pressure setpoint
   Set the desired chamber pressure setpoint within the ±15 mbar range using the touchscreen interface.
3. Initiate automatic purge cycle
   Initiate the automatic purge cycle to replace the chamber atmosphere with inert gas until water and oxygen levels drop below 1 ppm.
4. Monitor environmental conditions
   Monitor the water and oxygen display to confirm the environment stabilizes below 1 ppm before handling sensitive materials.
5. Activate regeneration when needed
   Activate the automatic regeneration cycle via the PLC when purification capacity is depleted, using a 5–10% H₂ mixture as regeneration gas.

This opposite 4-station glove box provides a reliable <1 ppm H₂O/O₂ environment via closed-loop circulation with PLC-automated regeneration, but requires a 99.999% inert gas source and 5–10% H₂ regeneration gas, plus substantial floor space and 2-ton weight for laboratory integration.

Positive

• Closed-loop automated atmosphere control: The integrated circulation fan and purification column maintain water and oxygen levels below 1 ppm with PLC-controlled automatic regeneration, eliminating routine manual intervention for sustained lab operations.
• Durable, high-stability analytical sensors: The ZrO₂ oxygen analyzer offers long service life and stability without the air-exposure limitations of fuel cells, while the water analyzer can be recovered via purge/regeneration to avoid premature replacement.

Trade-offs

• High-purity gas and hydrogen requirement: The system demands 99.999% inert gas (N₂, Ar, He) and a 5–10 vol% H₂ mixture for regeneration, requiring dedicated gas supply infrastructure and safety handling protocols.
• Large footprint and equipment weight: With dimensions 2440 × 1000 × 900 mm and a 2-ton mass, the glove box necessitates adequate floor space and load-bearing capacity in the laboratory, limiting placement flexibility.
