How Often Should Equipment Be Maintained?
The frequency of maintenance varies depending on the equipment and its usage. Generally, a combination of daily, weekly, monthly, and annual maintenance schedules is recommended:
Daily: Basic cleaning and inspection
Weekly: More thorough cleaning and minor adjustments
Monthly: Detailed inspections and calibrations
Annually: Comprehensive servicing and part replacements
Inspection: Regularly check for wear and tear, and ensure all parts are functioning.
Cleaning: Clean all surfaces and components to prevent contamination.
Lubrication: Apply lubricants to moving parts to reduce friction and wear.
Calibration: Calibrate instruments to maintain accuracy.
Documentation: Keep detailed records of maintenance activities and any issues encountered.
Blade dullness: Regularly replace or sharpen microtome blades.
Blockage: Ensure proper disposal of waste to prevent clogging in tissue processors.
Temperature fluctuations: Regularly check and calibrate cryostats and incubators.
Staining inconsistencies: Regularly clean staining machines and replace reagents.
Who Should Perform Equipment Maintenance?
Maintenance should be performed by trained personnel familiar with the specific equipment. In many laboratories, this responsibility falls to a
Histotechnologist or a designated lab technician. In some cases, specialized service engineers may be required for complex maintenance tasks.
