Volumetric instruments

The letters stand for the accuracy classes:

class A for higher accuracy
– class AS for higher accuracy of burettes and pipettes with definded waiting time
– class B for lower accuracy

The German Measurement and Calibration Regulation – valid from January 1, 2015 – requires certification of conformity by the manufacturer for volumetric instruments used for medical, pharmaceutical and commercial measurements (e.g. manufacture and testing of drugs). The regulatory compliance is certified by the marking DE-M. The conformity guarantees the compliance of the instrument with the German Measurement and Calibration Regulation and the valid standards.
For details of the procedure, please refer to the German Measurement and Calibration Regulation.
The user is responsible for application and providing of conformity certified instruments. The certificate of conformity is valid indefinitely unless otherwise specified by the manufacturer. Conformity certified instruments that have been manufactured before 1 January 2015, may still be used. Hecht certifies the conformity of volumetric instruments directly on the instrument. In case of disposable micropipettes on the inner packing. For some liquid handling instruments in the directions for use accompanying the instrument.

A lot certificate (showing mean value of production lot) is included in each original packing. An individual certificate of performance (showing the actually determined volume of the instrument) is available on request. Please specify in your order!
