Glovebox Maintenance – What Matters

A glovebox maintains a controlled inert gas atmosphere of argon or nitrogen, in which oxygen and moisture levels are often below 1 ppm. This condition can only be maintained if the glovebox is airtight, the gas purification system is functioning properly, and wear parts are in good condition. Regular maintenance is therefore not a luxury, but a prerequisite for reliable measurement data and safe operation—regardless of the manufacturer, whether MBraun, GS Glovebox, Jacomex, or Inert.

Why Regular Maintenance Is Important

Wear and tear on a glovebox rarely gives any obvious warning signs. Leaky gloves, porous seals, or a spent catalyst initially lead only to a slight increase in O₂ and H₂O levels. If this is overlooked, the quality of your work suffers—and in the worst case, the system comes to a standstill. Scheduled maintenance detects wear early, maintains high operational safety, and extends the system’s service life.

What to Check Regularly

• Gloves: the most common wear part—visually inspect for cracks and material fatigue; replace as needed. See the article “Replacing Glovebox Gloves” for details.
• Seals on doors and airlocks: Check for brittleness and proper sealing; replace as needed.
• Gas purification (molecular sieve & copper catalyst): Check condition and regeneration—read about how this works in “Glovebox Gas Purification.”
• Filters: Check HEPA/particle filters and—if present—solvent filters (activated carbon).
• Valves and pressure control: Test the function of the foot switches, overpressure/underpressure valves, and the automatic pressure control system.
• Leak Detection & Tightness Test: Perform an overpressure test to determine the box’s leak rate.
• O₂ and H₂O sensors: Check the calibration to ensure your readings are accurate.

Recommended Maintenance Intervals

The exact intervals depend on usage and application. As a guideline:

Do it yourself or sign a maintenance contract?

You can handle minor inspections in-house. For leak testing, sensor calibration, and the proper replacement of wear parts, it’s worth hiring a specialized service provider—especially if you have multiple systems from different manufacturers in use. With our KeT Care 360 maintenance contract, you get fixed service dates, predictable costs, and a dedicated contact person for all manufacturers. You can find all the details and the three plans (Eco, Standard, Premium) on the Maintenance & Repair page.

You can purchase wear and consumable parts such as gloves, filter cartridges, or seals directly from us—see the Glovebox Accessories & Consumables page for an overview.
