Understanding Pipette Calibration and Why It Matters

What is Pipette Calibration?

Pipette calibration verifies and documents that your liquid handling instruments dispense accurate volumes with the precision your procedures require. Our technicians use gravimetric testing methods, measuring the actual mass of liquid dispensed in accordance with ISO 8655 standards, testing pipettes at multiple points across their volume range to measure accuracy, precision, and uncertainty values.

If a pipette fails to meet manufacturer specifications or your facility’s acceptance criteria, we provide detailed out-of-tolerance reporting so you can make informed decisions about repair or replacement before the instrument compromises your data quality.

Benefits of Regular Pipette Calibration

Audit Confidence When It Counts Walking into regulatory inspections with complete, current, and technically defensible calibration records transforms audit anxiety into audit confidence. Our ISO 17025 accredited certificates provide documentation that satisfies even the most scrutinizing regulators.


Data Integrity You Can Defend When measurement results drive critical decisions, patient diagnoses, or regulatory submissions, calibrated pipettes ensure your data reflects reality – not instrument drift. This is the foundation of legally defensible documentation and scientifically valid results.


Cost Avoidance Through Early Detection Out-of-specification pipettes quietly compromise batches and invalidate test runs before anyone notices the problem. Regular calibration catches drift before it costs you production time, wasted materials, or failed inspections.


Extended Equipment Lifespan Properly maintained and regularly calibrated pipettes last longer and perform more reliably. Our calibration process identifies developing issues before they become failures, allowing preventive maintenance instead of emergency replacements.

Risks of Neglecting Pipette Calibration

Failed Audits and Regulatory Findings Inadequate calibration documentation is one of the first things regulatory inspectors check. What seems like routine administrative work becomes a business-threatening problem when regulators discover gaps in your calibration program.


Compromised Data That Can’t Be Defended Results generated with uncalibrated pipettes lack scientific validity and legal defensibility. If you can’t prove your instruments were accurate when you generated data, imagine invalidating months of research or scrapping production batches.


Expensive Product Losses and Rework Pipettes that drift out of specification don’t stop working – they just stop working accurately. By the time you discover the problem, you’ve already wasted expensive reagents, compromised test results, and potentially released non-conforming product.


Liability Exposure in Regulated Industries In pharmaceutical manufacturing and clinical diagnostics, measurement errors affect patient safety, product efficacy, and legal liability. When investigators trace problems to uncalibrated measurement equipment, the liability implications extend far beyond the laboratory
