How to Maintain Laboratory Equipment: Best Practices for Longevity

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

1. User checks: daily/weekly quick tests
2. In-house verifications: monthly/quarterly with reference materials
3. 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.
