Computer controlled automatic calibration machine with optical laser beams to prevent human error ISO/IEC 17025:2005 Accredited. Calibration Labaratory and ensure highest level of accuracy and precision BOROSIL Scientific performs the calibration process with fully automatic state-of-the-art calibration machines that eliminate any possibility of human error. This also ensures a high degree of repeatable measurements for all Borosil Volumetric products. BOROSIL Scientific has an in-house set-up of a wellequipped temperature-controlled calibration laboratory with precision electronic balances, thermometers and stopwatches that are traceable to national standards. Calibration of Volumetric Glassware is entrusted to only trained and experienced technicians. All Volumetric Glassware is calibrated either as To contain TC / In The contained quantity of liquid corresponds exactly to the capacity indicated on the article (e.g. graduated cylinders and volumetric flasks). To deliver TD / Ex The delivered quantity of liquid corresponds exactly to the capacity indicated on the article. (e.g. pipette and burettes). facility meets the BOROSIL Scientific These steps ensure that each and every Volumetric product leaving the highest international standards and can be used for various purposes with the highest degree of repeatability and accuracy. 1. Filling the Volumetric blanks with a precisely- defined amount of de-mineralized water under controlled temperature. 2. 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. 3. Cylinders, Burettes and Pipettes are marked at a minimum of two calibration points. 4. The wet surface area factor is always taken into account, throughout the process. 5. The calibration laboratory is temperature, light controlled and temperature is maintained at 23°C ± 2°C. The following steps are carried out by highly precise, fully automated computer-controlled machines:
