Providing analytical metrology leadership in UV/VIS calibration science for more
than 25 years as an established vital link in the FDA-regulated global supply chain


Stranaska Metrology Laboratory is an elite top-tiered commercial calibration laboratory that specializes in providing higher-order analytical spectrophotometric metrology services and standards for high-stakes scientific laboratory applications such as analytical instrument qualifications in FDA-regulated laboratories. Our uncompromising commitment is to provide only the highest level of science-based measurement standards and services that can support the scientific integrity and metrological defensibility of analytical calibration programs around the world.

Stranaska Metrology Laboratory – the only commercial spectrophotometric calibration laboratory in the world that backs the integrity of the certified values and uncertainties of their UV/VIS reference material standards with scientific metrological rigor.┬á For this very important reason, you avoid costly “false positive” or “false negative” AIQ scenario ramifications for UV/VIS absorption spectrophotometers because you can trust Stranaska certification results that will facilitate the establishment of a science-based foundation for meaningful test result interpretations and management decisions.

The Stranaska Metrology Laboratory is the original STRANASKA scientific initiative and today it remains central to all of the other newer STRANASKA scientific initiatives. The Metrology Laboratory has three (3) emphasis areas related to state-of-the-art calibrations of analytical UV/VIS absorption spectrophotometric reference materials:

  • Measurement Standards
  • Measurement Services
  • Measurement Research

Degree-credentialed analytical scientists include Lucy Davis (Physics), Naveen Singh Pradhan (Physics), Jens Yetter (Chemistry) and Gwendolyn Sullivan (Chemistry).
