The documentation should contain the values for accuracy and coefficient of variation as well as the testing procedure and test frequency. A distinction is made between: - Quality certificates (factory calibration Report) - Official calibration certificates ( Bureau of standards, DAkkS) ![](https://www.vitlab.com/fileadmin/_processed_/4/a/csm_csm_DAkkS_2a5db79111_7a96bcbf3f.jpg) **DAkkS CALIBRATION CERTIFICATE** The DAkkS calibration certificate documents officially the traceability of measuring results to national and international standards as required by the standards DIN EN ISO 9001 and DIN EN ISO / IEC 17025 for the monitoring of measuring instruments. A major difference between a factory calibration services and DAkkS laboratories is the accurate determination of the respective uncertainty of measurement guaranteed by the accredited laboratory and supervised by the DAkkS. DAkkS calibration certificates are appropriate in uses in which calibrations of an accredited laboratory are requested, where high level calibrations are demanded and for calibration of reference standards and instruments for comparative measurements. To order a new device with an individual certificate place “DAkkS/…” in front of the standard device catalogue number. **QUALITY CERTIFICATES** The VITLAB quality certificate is a factory calibration report on the basis of the quality assurance system according to DIN EN ISO 9001. Quality certificates are available as a batch or individual certificate. Devices from one production batch have the same lot number as the quality certificate. The certificate records for the specific batch the mean value, standard deviation and day of issue. In the case of an individual certificate, the volumetric instrument and the certificate bear an individual serial number in addition to the lot number. The certificate records besides the day of issue also the measured volume and the measurement uncertainty. To order a new device with an individual certificate place “EZ/…” in front of the standard device catalogue number. **CALIBRATION SERVICE** VITLAB offers a repair, maintenance and calibration service (incl. DAkkS calibration) for all Liquid Handling devices made by VITLAB. The calibration laboratory accredited by the “Deutsche Akkreditierungsstelle GmbH” (DAkkS) is authorized to issue DAkkS calibration certificates for the following instruments: Liquid Handling products like VITLAB piston-operated pipettes and burettes, VITLAB Dispenser and VITLAB volumetric plastic Labware.
