Preventative Maintenance Tips to Extend the Life of Your Lab Equipment
A freeze dryer that fails mid-cycle doesn’t just cost you a repair bill; it costs you the batch, the timeline, and sometimes the data behind it.
Consistent lab maintenance is what stands between your equipment and that kind of expensive surprise. Labec has supported Australian laboratories, hospitals and manufacturers with scientific equipment since 1945, and the labs that get the longest service life out of their gear are the ones that treat maintenance as routine.
Here are our top tips on how to maintain your lab equipment.
Key Insights
- Clean and inspect equipment daily or weekly to catch small issues before they become breakdowns.
- Calibrate on schedule, ideally through a NATA-accredited laboratory where traceable results matter.
- Book manufacturer-recommended servicing rather than waiting for a fault to appear.
- Keep equipment in stable temperature, humidity and dust conditions.
- Log every clean, calibration, service and repair to protect compliance and warranty cover.
Why Preventative Maintenance for Lab Equipment Pays Off
Preventative maintenance for lab equipment means fixing small issues before they become expensive ones. A worn autoclave seal or a fridge running a degree or two too warm rarely looks urgent, until it fails during a critical run and takes your results with it.
Regular lab equipment maintenance protects your data, budget and your compliance position. Instruments operating outside their calibrated range can skew results long before an alarm sounds, and unplanned downtime on high-value equipment costs far more than a scheduled service call. For labs working under ISO/IEC 17025 or GLP frameworks, documented maintenance also demonstrates that equipment remains fit for purpose.
How to Maintain Lab Equipment: Build a Schedule
Ad hoc checks aren’t a maintenance plan. Effective lab maintenance runs on tiers:
- Daily: Visual checks, seal inspection, noting any unusual noise or temperature drift.
- Weekly/Monthly: Deeper cleaning, filter and gasket checks, verifying data logs.
- Quarterly/Annual: Formal calibration, manufacturer servicing, safety testing.
Base the frequency on manufacturer guidance and how hard the unit works. A fridge running 24/7 in a busy pathology lab needs closer attention than one used occasionally. Dust, residue, and biological buildup are the most common causes of early equipment failure and the cheapest to prevent through regular cleaning. Staff who use equipment daily are usually the first to notice a problem, so give them a clear and simple way to report it.
Calibration and Servicing Keep Results Trustworthy
Calibration confirms an instrument is still measuring accurately; servicing keeps its internal components in working order. Both matter, and neither replaces the other.
NATA has accredited Australian testing and calibration laboratories since 1947, assessing them against the international standard ISO/IEC 17025. Where results need to be traceable and defensible, calibration through a NATA-accredited lab is worth the investment. For general servicing, Labec’s technical team supports equipment across its working life.
Equipment-Specific Maintenance Tips
Ovens and Heating Equipment
Heating mantles, heating elements, and controllers need to be checked regularly, with spills cleaned before they bake onto surfaces.
Incubators
Incubators rely on stable temperature and humidity, so check door seals and sensors often. See our guide to what a laboratory incubator is used for if you’re reviewing your setup.
Autoclaves
Autoclaves are classified as pressure equipment under Australian Standard AS 3873, which sets minimum requirements for operation, inspection and maintenance records. Our guide on how to maintain your laboratory autoclave covers seal checks and test cycles.
Refrigerators and Freezers
Units storing vaccines or temperature-sensitive samples, such as lab freezers, should follow the Australian Government’s Strive for 5 guidelines: temperatures checked twice daily, kept within +2°C to +8°C.
Freeze Dryers
Freeze dryers need regular vacuum seal and condenser checks. Our commercial freeze dryer range is built for sustained, high-demand use.
Water Baths
Water baths should be descaled and refilled with clean water regularly to prevent scale buildup from affecting temperature accuracy.
Environmental Conditions Matter
Ambient temperature, humidity and dust levels around your equipment affect how hard it has to work, and how long it lasts. Keep units away from direct sunlight, poor ventilation, or overcrowded benches, and ensure airflow around compressors and vents isn’t blocked.
Record-Keeping Protects Compliance
Every clean, calibration, service and repair should be logged against the individual unit. This supports internal audits, accreditation reviews and warranty claims, and flags early if a piece of equipment needs more attention than it used to.
Signs Your Lab Equipment Needs Attention
Even with a solid maintenance schedule, equipment can start showing warning signs between services. Watch for:
- Unusual noise or vibration from motors, compressors or pumps.
- Temperature, pressure or humidity readings drifting from the set point, even slightly.
- Error codes or fault lights that weren’t there before.
- Longer cycle times. An autoclave or freeze dryer taking longer to complete a run is often an early sign of a failing seal or component.
- Visible wear on door seals, gaskets, cords or fittings.
Catching any of these early and booking a service call, rather than waiting for a full failure, is usually the difference between a minor repair and a major one.
Let Labec Support Your Lab Maintenance Routine
Keeping up with preventative maintenance across a full lab, running ovens, incubators, autoclaves, fridges and freeze dryers side by side, takes time most teams don’t have spare.
Labec’s technical support and servicing team works with government, medical and pharma laboratories across Australia to keep equipment calibrated, compliant and reliable for years. Get in touch with our team to talk through a maintenance plan for your lab.
FAQs
How often should lab equipment be serviced?
It depends on the equipment type and usage, but most manufacturers recommend annual servicing at a minimum, with more frequent checks for high-use items like autoclaves and fridges. Always follow the specific schedule in your equipment’s manual.
What’s the difference between calibration and servicing?
Calibration checks and corrects measurement accuracy against a known standard. Servicing covers the physical condition of the equipment, including seals, filters, moving parts and safety systems. Well-run lab maintenance includes both.
Can preventative maintenance really extend equipment lifespan?
Yes. Equipment that’s cleaned, calibrated and serviced on schedule experiences less wear and fewer sudden failures than equipment run until something breaks, which means fewer early replacements and more consistent results in the meantime.
