What are the best practices for maintaining common chemical laboratory instruments?

Best Practices for Maintaining Chemical Laboratory Instruments
1. Daily Cleaning and Corrosion Prevention

Rinse glassware with warm water, mild detergent, or acetone. Avoid using abrasives or strong acids to prevent surface scratches and corrosion.

Promptly dry metal parts and apply rust-inhibiting oil to extend their service life.
2. Temperature and Environmental Control

Avoid prolonged exposure of laboratory benches and instruments to temperatures exceeding 135°C to prevent cracks or deformation caused by thermal expansion and contraction.

Store instruments in a dry, ventilated cabinet to prevent moisture-induced rust or chemical leaks.
3. Regular Inspection and Calibration

Inspect instrument fasteners, seals, and power cords monthly to ensure they are not loose or deteriorating.

Calibrate high-precision equipment such as temperature sensors and electronic balances to ensure accurate experimental data.
4. Clean and Separate Instruments After Use

Clean instruments immediately after experiments and store instruments of different materials separately to prevent cross-contamination. Corrosive reagent residues should be cleaned specifically to prevent long-term damage to the instrument.
