Photometric Accuracy Verification Filters
Certified against National Institute of Standards and Technology (NIST) standards and surpassing NIST-2031a requirements, these filters provide a reliable and permanent benchmark for validating both laboratory spectrophotometers and Kemtrak process photometers. Unlike fragile liquid calibration standards, Kemtrak verification filters never need to be replaced, eliminating the cost, inconvenience, and safety risks associated with handling toxic liquid standards.
Spectroscopy is subject to stringent regulations from pharmacopoeias and quality assurance organizations worldwide, where maintaining photometric accuracy is crucial for ensuring correct readings at assigned wavelengths. Kemtrak photometric accuracy verification filters confirm whether instrument readings align with certified benchmark values of the standard, which is particularly important in regulated GMP environments where data integrity and instrument qualification are mandatory requirements. Manufactured from durable Inconel (metal) on quartz with a scratch-resistant protective coating, these filters deliver long-lasting, maintenance-free performance and high accuracy across a certified absorbance range of 200 nm to 2 000 nm, covering the full UV-VIS-NIR spectrum. Consistent verification with Kemtrak filters guarantees reliable measurements, regulatory compliance, and reproducibility of results across all analytical applications.
