Calibration standards for spectrophotometers
Certified calibration standards ensure measurement results. Spectrophotometers only provide correct results in the long run, if they are recalibrated regularly. UV/Vis calibration standards from accredited Hellma® Analytics calibration laboratory are traceable to primary standards of the NIST and thus assure the international comparability of measurement results. Internal quality requirements can therfore be met ideally. Glass filters: for testing spectrophotometers. Photometric accuracy in the visible spectral region. Liquid filters: for testing spectrophotometers to acc. to European Pharmacopoeia, wavelength accuracy, photometric accuracy, stray light behavior, resolution. Technical Data: - Height: 48mm - Width: 12,5mm - Depth: 12,5mm
