Why UV/Vis reference materials from Hellma make the difference

Every single UV/Vis reference material is measured at Hellma Analytics in the accredited calibration laboratory, after which the calibration certificate is issued. Hellma Analytics runs the only calibration laboratory in Germany, which is accredited for the measurement of UV/Vis reference materials by DAkkS according to 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. Whether glass filter or liquid filter - Reference materials from Hellma ensure reliable measurement results and guarantee highest process transparency.


Basis for safe and reliable measurement results

Spectrophotometers in instrumental analytics have to be checked on a regular basis! Quality assurance and control regulations, such as B. ISO 9001, GLP, GMP and the pharmacopoeias, require a regulated performance verification of the UV / Vis spectrophotometers in use. Reference materials from Hellma Analytics help you with this task and create the basis for safe and reliable measurement results.


Wide range of liquid- and glass filters

In the Hellma Analytics calibration laboratory, which is accredited* to DIN EN ISO 17025, we manufacture UV/Vis reference materials based on the regulatory codes issued by NIST (National Institute of Standards and Technology), ASTM (American Society for Testing and Materials) and Pharmacopoeias (Ph. Eur., DAB, USP).
