STRANASKA® Spectral Bandwidth/Resolution Standard  NEW!
This reference material artifact is intended for the verification and validation of the spectral bandwidth (SBW) of molecular absorption spectrophotometers in the ultraviolet (UV) region of the electromagnetic spectrum. It has been proven to provide significant advantages over the out-dated toluene/hexane solution. The solution is flame-sealed in a fused-silica cuvette of optical quality. The science-based calibration procedure ensures rigorous measurement traceability of the certified apparent absorbance ratios to the NIST SRM 1935a photometric standard.
