Absorbance Linearity Standards
Each 5 vial set contains 4 standard solutions in 6ml borosilicate glass vials (Standards 1 to 4) sealed with crimped aluminium overseal with PTFE faced septa and 1 reference solution (nominal contents 4ml). The absorbance values of standards 2, 3 and 4 are nominally 75%, 50% and 25% of Standard 1.

Product Number	Wavelength Coverage (nm)	Spectral Band Maxima (nm)*
SLM-LCUV-004	210-260	212, 261
SLM-LCUV-005	240-650	258, 416, 630

These linearity standards are traceable to Certified Reference Material LGC 2011, set S2 14, traceable to the NPL and NIST SRM 2030a, Filter 30%T-31 and SRM 1930, set 183 NIST (National Institute for Science and Technology, USA). All standards have an unopened shelf life of 12 months when stored correctly at temperatures below 25°C and come with a certificate of traceability.
