Agilent Neutral Density Filter set, Cert. UV Std 190032100

Certified glass neutral density standards to certify UV instruments from 440 to 635 nm for accuracy and linearity to USP. Set of three certified neutral density (glass filter) standards of 0.5, 0.7, and 1.0 Abs, required to certify performance of UV-Vis spectrophotometers for the determination of photometric accuracy and linearity from 440 to 635 nm to US Pharmacopeia requirements. Traceable to NIST.

Key Features:

• Three certified glass neutral density standards: 0.5, 0.7, and 1.0 Abs
• Certifies UV instruments across 440 nm to 635 nm
• Designed to certify photometric accuracy and linearity to US Pharmacopeia (USP) requirements
• Traceable to NIST
• Technique: UV-Vis

Advantages:

• Provides certified standards specifically required to certify UV-Vis spectrophotometer performance for photometric accuracy and linearity to USP (explicit requirement).
• Covers the 440–635 nm wavelength range used for USP photometric/linearity verification, enabling compliant instrument certification.
• Traceability to NIST offers documented metrological traceability for calibration and regulatory records.
• Three absorbance levels (0.5, 0.7, 1.0 Abs) allow verification across multiple points of the instrument photometric scale.
