Biologists rely on a wide range of electrical equipment to conduct experiments, collect data, and analyze results. From microscopes, centrifuges, and incubators to laptops, freezers, and field devices, your research depends on equipment working safely and reliably.
PAT testing (Portable Appliance Testing) ensures that all electrical devices in your lab or fieldwork setup are safe, compliant, and ready for use, protecting both you and your research.
What Is PAT Testing?
PAT testing is the process of checking electrical appliances to ensure they are safe to use. It involves:
- Visual inspection – checking for frayed cords, damaged plugs, or visible wear.
- Electrical testing – using specialist tools to detect hidden faults that could cause shocks, fires, or equipment failure.
After testing, each device is labelled pass/fail, and a certificate is issued. For biologists, PAT testing helps maintain a safe, professional, and compliant working environment.
Why PAT Testing Matters for Biologists
Even minor electrical faults can compromise research or create hazards. PAT testing helps by:
- Protecting researchers and colleagues – preventing electric shocks, fires, or accidents.
- Ensuring uninterrupted experiments – avoiding equipment failure that could ruin time-sensitive research.
- Maintaining professional credibility – safe, reliable labs demonstrate rigorous standards.
- Supporting insurance and compliance – many laboratory policies require evidence of PAT-tested devices.
- Extending equipment lifespan – early detection of faults prevents damage to costly instruments.
What Equipment Should Biologists Get PAT Tested?
Any electrical device used in labs, offices, or fieldwork should be included:
- Microscopes, centrifuges, and incubators
- Laptops, tablets, and desktop computers
- Freezers, refrigerators, and water baths
- Extension leads, power strips, and adapters
- Small appliances in the lab or field, such as heaters, lamps, or fans
Even equipment used occasionally should be included to prevent hazards.
How Often Should PAT Testing Be Done?
Frequency depends on usage:
- Annually – for frequently used, portable equipment.
- Every 2 years – for stationary or low-use devices.
- After visible damage or repairs – always retest before use.
Many biology labs schedule PAT testing before major experiments, the start of the academic year, or annually to ensure safety and operational reliability.
Is PAT Testing a Legal Requirement?
PAT testing is not explicitly required by law, but UK and European regulations mandate that all electrical equipment used at work must be safe. PAT testing is the recognised method to demonstrate compliance and is often requested by insurers, safety auditors, or institutional review boards.
Final Thoughts
As a biologist, your focus should be on research, discovery, and analysis—not worrying about faulty electrical equipment. PAT testing ensures that all your lab and field devices are safe, reliable, and professional, letting you work with confidence.
Because the only sparks in your lab should come from scientific discovery—not electrical hazards.
