Unplanned breakdowns drain budgets. Here’s how to maintain laboratory equipment so your lab runs safely, smoothly and in compliance.
Modern labs rely on precise, high-value equipment to generate accurate data, ensure safety, and stay compliant with standards like ISO 9001, ISO/IEC 17025, and GLP/GMP principles.
But, even the best centrifuge or LC-MS system can become a liability without a solid maintenance routine.
In this guide, we show you how to maintain laboratory equipment through a practical mix of daily checklists, calibration insights, documentation best practices and smart consumable sourcing, whether you're managing an academic, pharmaceutical or industrial lab.
Build a Maintenance Culture (Foundations & SOPs)
Extending equipment life starts with consistent routines and clear responsibilities, not just occasional repairs. Lab equipment maintenance is not a one-off task, but a shared responsibility to be embedded in your team’s workflows and your lab’s quality system.
Start with clear roles:
- End-users: daily care, routine checks, and logging
- In-house engineering/facilities: mechanical interventions, preventative servicing
- External service providers: calibrations and certifications for regulated instruments
Standard operating procedures (SOPs) should cover cleaning, inspection, performance checks, escalation points, and risk assessments.
Maintain a detailed asset register tracking:
- Calibration and service history
- Location and responsible owner
- Maintenance intervals and warranty coverage
- Equipment ID, serial number, installation date
- Criticality ranking (essential, backup, non-critical)
Staff training should include maintenance, with competency sign-offs and refreshers. For ISO 9001 compliance, maintenance documentation must follow version control and be centrally stored. Consider a CMMS or a structured spreadsheet with owners and timestamps.
Daily, Weekly & Monthly Checklists (Reusable Template)
You can streamline preventative maintenance if you do it right. It’s about building repeatable habits that spot issues before they snowball.
Daily tasks (user-led):
- Confirm alarms and interlocks
- Inspect for damage, spills, loose cables
- Check calibration status and warm-up
- Log performance metrics (balances, fridges, incubators, gauges)
Weekly tasks:
- Review firmware logs/software alerts
- Inspect utility inputs (gas, DI water)
- Check seals, hinges, moving parts
- Wipe down surfaces with compatible cleaners
Monthly/Quarterly tasks:
- Test UPS or backup power
- Backup data
- Validate temperature probes, alarms, filters
- Perform in-house calibration checks
Annually:
- IQ/OQ/PQ on regulated systems
- Review maintenance frequency
- Arrange full servicing & recalibration
Tip: Create a shared template with task, frequency, responsible person, linked SOP, and sign-off.
Cleaning & Care by Equipment Type
Each category of lab equipment has specific maintenance requirements:
Pipettes & Controllers
- Clean exterior daily with 70% IPA
- Disassemble & lubricate weekly
- Rotate pipettes, store vertically
- Use low-retention, high-quality tips
Ocon stocks a full range of pipettes.
Balances
- Keep level, away from drafts/vibrations
- Run daily calibration/test weights
- Prevent corrosion: clean spills quickly
- Annual ISO/IEC 17025 calibration
Centrifuges
- Inspect rotors weekly
- Clean with neutral detergent (avoid bleach)
- Track rotor lifespan; replace per OEM
- Always balance loads and check locks
Safety reminder: Dispose of cleaning residues via approved hazardous waste channels.
Incubators & Ovens
- Wipe walls weekly
- Monthly: clean/refill pans, check seals & CO₂ sensors
- Map temps after service/relocation
Cold Storage (Fridge, Freezer, ULT)
- Check & log temperatures daily
- Clean gaskets weekly
- Manual/auto-defrost checks
- Validate alarms & UPS monthly
- Annual temperature mapping
Chromatography & LC-MS
- Use LC-MS grade solvents
- Filter & degas mobile phases
- Flush systems daily
- Replace pump seals monthly
- Prevent clogs with guard columns & filtration
Fume Cupboards & Safety Cabinets
- Keep sashes closed
- Certify airflow every 6–12 months
- Replace filters as specified
- Test alarms regularly
Glassware
- Use neutral detergents
- Avoid abrasive scrubbers
- Replace cracked/chipped glass
- Air-dry in dust-free racks
- Maintain joints, stopcocks, stoppers
Ocon offers precision glassware.
Calibration & Verification
- User checks: daily/weekly quick tests
- In-house verifications: monthly/quarterly with reference materials
- Third-party calibrations: annually, accredited & traceable
Label instruments with calibration date, due date, and status. Quarantine overdue/failed equipment.
Spares, Consumables & Compatibility
- Keep critical spares on-site
- Use OEM-approved lubricants
- Source high-purity solvents & precision consumables
Tip: Ocon offers fast nationwide delivery across Ireland & UK.
Audit-Ready Documentation
- Date/time of maintenance
- Task performed
- Responsible person/signature
- Readings or checks
- Parts used/replaced
- Deviations & CAPA
- Attach calibration/service reports
Contamination Control & Waste
- Dedicated cleaning kits (colour-coded)
- Validate residue removal
- Label/segregate chemical waste
- Use ADR-compliant disposal services
Ocon provides: ADR-certified drivers, DGSA oversight, ISO 9001:2015 procedures, full traceability.
When to Repair, Service or Replace
- Rising service costs
- Unsupported/missing parts
- Frequent breakdowns
- Failed calibrations
- End-of-life/safety notices
When replacing: plan downtime, validate new systems, use vendor-managed delivery. Ocon can assist with logistics and inventory.
Sample Weekly Maintenance Schedule
| Day | Task |
|---|---|
| Monday | Balance checks and cleaning |
| Tuesday | Centrifuge rotor inspection |
| Wednesday | Incubator wipe & CO₂ probe test |
| Thursday | Fume cupboard airflow/alarm test |
| Friday | LC/HPLC flush, leak check & waste review |
