Micropipette
Calibrate micropipettes to ISO 8655 for life science, analytical chemistry, and pharmaceutical laboratories.
Standards
ISO 8655-1 to 8655-7, ISO/IEC 17025
Typical Interval
12 months
Uncertainty Range
±0.5–2% of nominal volume
What Is Micropipette?
Micropipettes aspirate and dispense liquid volumes from μL to mL — the fundamental tool of life science, analytical chemistry, and medical research labs. ISO 8655 calibration verifies accuracy and repeatability by the gravimetric method (weighing dispensed water) at a minimum of 3 test volumes.
Applicable Standards
Primary standards: ISO 8655-1 to 8655-7, ISO/IEC 17025
ISO/IEC 17025-accredited laboratories must maintain an unbroken traceability chain from the calibration result back to NIMT (Thailand's national metrology institute) or another internationally recognised NMI.
Typical Measurement Uncertainty
Expanded uncertainty is typically ±0.5–2% of nominal volume, depending on the measurement range, reference equipment used, and environmental conditions. The actual uncertainty will be stated on your calibration certificate.
Recommended Calibration Interval
A calibration interval of 12 months is generally recommended. The appropriate interval for your specific instrument depends on usage frequency, environmental exposure, and any applicable regulatory or customer requirements.
What Your Calibration Certificate Will Include
- Calibration results — instrument indication vs. reference value at each test point
- Error and expanded uncertainty (U) at k=2 (95% confidence level)
- Traceability chain to NIMT or a recognised NMI
- Environmental conditions during calibration (temperature, humidity)
- Calibration date, certificate number, and authorised signature

Frequently Asked Questions
Why is it important to calibrate a Micropipette?+
Analytical measurements underpin quality control decisions, safety assessments, and regulatory submissions. An uncalibrated Micropipette produces data that cannot be trusted or defended in an audit. Calibration verifies performance to ±0.5–2% of nominal volume per ISO 8655-1 to 8655-7, ISO/IEC 17025.
How often should a Micropipette be calibrated?+
Most Micropipettes should be calibrated every 12 months under normal operating conditions. High-use environments, harsh conditions (vibration, temperature extremes), or regulatory requirements (FDA, GMP, ISO 17025) may necessitate more frequent calibration. Always follow the manufacturer's recommended interval as a baseline and consult your lab's quality plan.
What does a Micropipette calibration certificate show?+
A calibration certificate issued under ISO/IEC 17025 includes: the instrument identification (make, model, serial number), the reference standards used (with their own traceability chain), the measurement points tested, before/after correction values, the expanded measurement uncertainty (±0.5–2% of nominal volume), the environmental conditions during calibration, the calibration date and next-due date, and the signature of the authorized calibration engineer. This certificate is the evidence required for audits and accreditation.
