This is a matched pair (set of 2) of high-precision micro cuvettes designed for spectrophotometry. Featuring an ultra-short 1mm path length and a corresponding 0.35 mL volume, they are specifically engineered for analyzing highly concentrated samples or conserving extremely limited sample volumes. Made from UV-grade quartz for broad wavelength compatibility (UV-Vis-NIR), these cuvettes have frosted (white) side walls for easy handling and include lids to prevent sample evaporation.
