Secondary Calibration Standards for Spectrophotometers, Hellma®

Certified UV/Vis calibration standards for spectrophotometers
To supply accurate results over the long run, spectrophotometers need to be calibrated in regular intervals. To this end, the Hellma Analytics calibration lab certified pursuant to DIN EN ISO 17025 offers ready-to-use, DAkkS certified calibration standards. Using UV/Vis calibration standards from the accredited Hellma calibration lab guarantees that the calibration operations performed are traceable to the NIST (National Institute of Standards and Technology) primary standards and the standards of the major pharmacopoeias (EP, DAB, USP).
The certified Hellma Analytics reference materials provide the user with a clean, easy, and efficient solution for checking the spectrophotometer.
