Daily Routine Maintenance of Laboratory Glove Boxes

Standard daily maintenance is essential to stabilize the internal water and oxygen index of laboratory inert gas glove boxes and extend equipment service life. Operators must complete standardized checks before and after daily experiments. First, inspect glove surfaces for cracks, pinholes and air leakage, and replace aging butyl rubber gloves timely to avoid external air infiltration. Second, monitor real-time water and oxygen readings; keep the purification circulation system running continuously to maintain the internal environment below 1 ppm. Third, clean the inner chamber regularly with anhydrous ethanol to remove residual chemical powder, electrolyte and organic contaminants, which will pollute purification materials. Besides, check transition chamber airtightness and vacuum pump operating status every shift. Staff shall strictly forbid placing wet, corrosive and unsealed items inside the box. Recording daily operation data, gas consumption and parameter changes helps early identify potential faults. Scientific daily maintenance reduces equipment failure rate, guarantees repeatable experimental results, and cuts long-term maintenance costs for material and battery laboratories.
