💉 Pipette Uncertainty Training Course
Learn how to calculate pipette calibration uncertainty step by step — compliant with ISO/IEC 17025, ISO 8655-6, and ISO/TR 20461:2023.
🚀 Master Pipette Uncertainty with Confidence
Are you struggling to calculate pipette calibration uncertainty for ISO/IEC 17025?
This beginner-friendly online course teaches you exactly how to estimate pipette measurement uncertainty using the latest ISO standards:
- ISO/TR 20461:2023,
- ISO 8655-6 (gravimetric method),
- EURAMET CG-19, and
- DKD R-8-1.
I spent many hours going through these documents to ensure you estimate uncertainty that meets ISO/IEC 17025 requirements.
We have received a ton of requests this year (from labs all over the world) to estimate pipette uncertainty in accordance with ISO/TR 20461:2023. Many of these labs got nonconformities during their last assessment because their uncertainty budgets did not meet the new ISO/TR 20461.
So, we estimated uncertainty for them so they could renew their accreditation. As a result, I decided to create this course to help others take advantage of what we learned and the uncertainty calculator template that we use.
In just 2 hours, you’ll learn step by step how to build a complete pipette uncertainty budget — with examples, templates, and Excel demonstrations.
👉 Perfect for lab managers, calibration technicians, quality managers, auditors, and consultants.
Whether you’re responsible for calibration, testing, or quality assurance, you’ll get the tools, techniques, and templates needed to produce accurate, validated uncertainty budgets.
🔍 Why Pipette Uncertainty Matters
ISO/IEC 17025 requires accredited laboratories to estimate measurement uncertainty. Pipettes are one of the most commonly calibrated instruments — yet also one of the most challenging uncertainties to estimate correctly.
Without proper training, labs risk:
- Incorrect or incomplete uncertainty budgets
- Audit findings and nonconformities
- Wasted time trying to interpret ISO standards
This course makes pipette uncertainty clear, practical, and ISO 17025 compliant.

Demonstration 1: Complete Pipette Uncertainty Estimation
Finally, the last module is a demonstration where you get to watch me perform a full uncertainty analysis from start to finish. You will see where I get the data from, how I perform each evaluation from the lessons, and how I add the results to the uncertainty budget. Unlike any other course, you will see the instructor actually perform an uncertainty analysis using the methods and formulas given in the lessons. This is what makes my courses the best!

❓ Frequently Asked Questions
Q: What is the uncertainty of a pipette?
According to ISO/TR 20461:2023, a pipette’s uncertainty is a combination of uncertainty components (following the GUM method) related to the liquid delivery process of a piston-operated volumetric apparatus (POVA), such as: repeatability, reproducibility, equipment, environment, method, handling, and POVA related influences. This course covers all of these and shows you how to calculate each one of these uncertainties step by step.
Q: How do you calculate pipette calibration uncertainty?
To estimate uncertainty for pipette calibrations, you need to follow ISO/TR 20461:2023. Additionally, you will need to gather information from the ISO 8655-6, EURAMET CG-19, and DKD-R 8-1. In this course, I cover everything you need to know with Excel templates and worked examples.
Q: Is this training only for Eppendorf pipettes?
No – this training applies to all volumetric pipettes, including air cushion pipettes, positive displacement pipettes, fixed volume pipettes, variable volume pipettes, multi-channel pipettes, and micro-pipettes. Essentially, any pipette or POVA item calibrated following the gravimetric method in ISO 8655-6 and ISO 8655-7.
