This is a set of two high-quality, standard 10mm path length cuvettes, the most common and versatile size used in spectroscopy. Each cuvette has a nominal volume of 3.5 mL.Constructed from UV-grade fused quartz, these cuvettes are transparent across the entire UV, Visible, and Near-Infrared (NIR) spectrum (approx. 190 nm – 2500 nm). This makes them the ideal "all-purpose" cuvette for any UV-Vis spectrophotometer, especially for deep-UV applications like measuring DNA, RNA, or protein concentrations.
