The Starna 1-Q series are quartz cuvettes that are usable from 170-2700nm. The most common size (universal for all spectrometers) is the 1-Q-10 with a 10 mm path length. Short path lengths like the 1-Q-1 are often used in biological applications (DNA-Protein ratios) when dilution is not an option. Long path length such as 1-Q-100 are of...
