The basis for secure and reliable measurement results!

Although checking measuring equipment to ensure accurate results has long been common practice for analytical balances, it still tends to take something of a backseat where spectrophotometers are concerned. Spectrophotometers are important instruments that play a major role in processes such as production control and ensuring product quality. 

Laboratories have become considerably more aware of the need to check that their spectrophotometers are working properly. These precision tools are also subject to mandatory checks under DIN EN ISO 9001

The standard clearly stipulates that measuring equipment must be calibrated or verified, either at regular intervals or before use, using measurement standards that can be traced back to international or national standards. An increasing number of laboratories are calibrating their spectrophotometers with Hellma reference materials to ensure their quality of work and the conformance of regulations.

You can have your UV/Vis reference materials (including other manufacturers) recertified in the Hellma calibration laboratory based on DIN EN ISO/IEC 17025! The accreditation is valid only for the scope listed in the annex of the accreditation certificate D-K-18752-01-00.

Hellma reference materials will be delivered in a high-graded pelicase
