Are there any microplate readers that meet GLP documentation and calibration requirements?

Yes. Many microplate readers can be used in GLP-regulated environments, but the key point is that GLP compliance is not just a property of the instrument itself — it depends on the instrument, its documentation, calibration/qualification package, software controls, and your lab’s SOPs.

What to look for

A microplate reader is suitable for GLP work if it comes with:

• Traceable calibration documentation
• Installation Qualification (IQ) / Operational Qualification (OQ) support
• Service documentation and maintenance records
• Audit trails and user access controls in the software
• Data integrity features such as:
  • secure data storage
  • electronic signatures, if needed
  • version control
• Validation support materials from the manufacturer
• Regular performance checks and recalibration procedures

Commonly used GLP-capable brands/platforms

Several major vendors offer microplate readers that are widely used in regulated labs and can support GLP workflows, for example:

• Molecular Devices
• BioTek / Agilent
• Tecan
• PerkinElmer / Revvity
• BMG LABTECH
• Promega and others, depending on the model

Important distinction

Even if a vendor says a reader is “GLP-ready” or “compliant,” you still need to:

• qualify the instrument in your facility
• verify calibration intervals
• document acceptance criteria
• validate the software and methods for your use case

Best next step

If you want, I can help you narrow this down by:

1. Assay type: absorbance, fluorescence, luminescence, Alpha, etc.
2. Regulatory context: GLP, GMP, 21 CFR Part 11, ISO 17025
3. Budget range
4. Need for reader + washer + incubator integration

If you tell me your application, I can suggest specific models and what documentation to ask the vendor for.
