Right after the blank glasswares are produced, ISOLAB accomplishes the calibration process with fully automatic state-of-art calibration machines which are only used rarely by well known manufacturers.
The following steps are carried out by fully automated computer controlled machines with the highest level of precision:
- Filling in the volumetric blanks with precisely defined amount of water under fixed temperature.
- Application of the calibration mark with a diamond tool at the lowest meniscus point.
- Cylinders, burettes and pipettes; application and marking of minimum two calibration lines.
- The wet surface area factor is always taken into account throughout the process
All calibration laboratories at ISOLAB are strictly controlled and the regular calibration temperature is 20 °C. This temperature is very important for the accuracy so that if the environmental temperature is different than 20°C, calibration machines have to be adjusted accordingly.
All volumetric glassware is calibrated either as; “To contain” “TC, In” or “To deliver” “TD, Ex”.
