Miscellaneous Laboratory Equipment Maintenance Guide
Laboratories contain a wide variety of equipment beyond the major instruments. Systematic maintenance of all equipment ensures reliable results and laboratory efficiency.
I. Water Baths
- Use distilled or deionized water to prevent scale buildup
- Clean the bath monthly and replace the water
- Add a biocide to prevent microbial growth if the bath is used at temperatures conducive to growth
- Verify temperature calibration quarterly with a certified thermometer
II. Incubators
- Clean the interior regularly to prevent contamination
- Verify temperature uniformity by measuring at multiple locations
- Check carbon dioxide sensors for proper calibration if equipped
- Replace HEPA filters on schedule for cell culture incubators
III. General Practices
- Maintain a preventive maintenance schedule for all laboratory equipment
- Document all maintenance, calibration, and repairs in equipment logbooks
- Train laboratory personnel on proper equipment use and basic troubleshooting
- Label equipment with calibration status and next due date
- Establish a process for reporting and tracking equipment issues
