NIST-traceable - NIST-traceable certificates accompany each kit; the kit-to-kit lot variance is better than +/- 1%. Absorbance charts are supplied with data collected on NIST-calibrated instruments.
Stable - The standards are comprised of microsphere polymer beads suspended in ultrapure water and will not settle out of solution.
Non-toxic, non-carcinogenic - No special handling, storage or disposal precautions need to be taken with the Ocean Optics standards. Material safety data sheets are supplied with each kit.
Easy-to-use - The Ocean Optics standards are poured directly from their 125-mL bottles without dilution or special sample preparation. The standards are not photosensitive and do not require refrigeration.
Cost-effective - Available for only $430, the kits contain a volume of standards that can provide up to 100 calibrations. The standards have a one-year shelf life.
