Stranaska Scientific LLC has the ONLY spectrophotometer filter calibration laboratory in the world that can PROVE and DEMONSTRATE its NIST heritage!​ This is critically important because the scientific credibility of the certified results of a UV/VIS filter can not be any better that the scientific validity and defensibility of the analytical measurement design of the calibration procedure used for the certification.

The conceptual proof and transparency of the experimental realization of a calibration laboratory’s declaration of metrological traceability is a key quality measure of its technical competence for UV/VIS filter recertification. Our traceability data resource document, which provides additional support to this Report of Calibration, is available post-calibration at any time at separate cost through Stranaska Scientific Documentation Services.
