Metrology Driven Calibration
Every measurement has a level of uncertainty associated with it. The lower the uncertainty, the better the measurement quality, and the greater the accuracy and reliability of the measurement process. Conversely, high measurement uncertainty signifies a high level of “doubt” about the measurement itself.
To reduce measurement uncertainty, it is necessary to identify the sources of that uncertainty, and to quantify these factors and report them along with the measurement result. This is the “measurement uncertainty” or mu value. The more tightly these factors are controlled, the smaller the mu and the more accurate the resulting pipette calibration. At Pipettes.com, we have isolated the following principal factors that impact the accuracy, repeatability and measurement uncertainty of our gravimetric pipette calibrations:
Accordingly, our laboratory and process controls are designed to stabilize these factors, and therefore to provide optimal conditions for a metrology-driven pipette calibration using gravimetric analysis.
Accurate Pipette Calibration and Low Measurement Uncertainty Is Impacted by the Facility & Equipment
The ISO 8655 standard defines the sensitivity of the test equipment required for a valid calibration measurement. At Pipettes.com, we not only meet these requirements, we exceed them, to ensure that even sub-microliter volumes are accurately measured.
Among the test equipment and systems we use in our pipette calibration to minimize and control measurement uncertainty for every test volume in our scope, are the following:
