Starna Green is a general-purpose absorbance reference designed for the routine qualification of ultraviolet and visible spectrophotometers within the wavelength range of 250 nm to 650 nm. It is specifically developed for instruments with wider bandwidths up to 20 nm, but remains suitable for spectrophotometers of all bandwidths.
The solution contains three well-defined peaks at wavelengths of 258 nm, 416 nm, and 630 nm for wavelength calibration and can be used for absorbance values up to 5 A. It is a stable, non-toxic, and REACH-compliant aqueous dye solution, calibrated to certify both wavelength and absorbance across the UV-visible spectrum.
