Filling the volumetric blanks with a precisely defined amount of demineralized water under controlled temperature.
The meniscus is determined with a laser controlled camera at the exact lowest point of the water level and the calibration mark is made with a fine diamond wheel. This gives accuracies that cannot be achieved by manual calibration.
Cylinders, burettes and pipettes are marked at a minimum of two calibration points.
The wet surface area factor is taken into account throughout the process.
The contained quantity of liquid corresponds exactly to the capacity indicated on the article (e.g. graduated cylinders and volumetric flasks
The delivered quantity of liquid corresponds exactly to the capacity indicated on the article (e.g. pipettes and burettes)
