Certified reference standard for certification of UV instruments to USP requirements. Includes 0.006% potassium dichromate plus perchloric acid blank and neutral density filters of 0.5, 0.7 + 1.0 Abs. for photometric accuracy tests. Also includes 4% holmium perchlorate in 10% perchloric acid for wavelength accuracy tests. Each solution is sealed in a quartz cuvette. A certificate of calibration with NIST traceability is included for each solution/filter. Certified reference standard for certification of UV-Vis spectrophotometers to US Pharmacopeia requirements.
