The most popular 10 mm quartz cuvettes with stoppers are cuvettes with rectangular test tubes made of quartz material for use in UV-Vis spectroscopy measuring systems. Like conventional test tubes, they are used to store aqueous solutions. Regular test tubes are useful in chemical reactions. UV-Vis cuvettes, on the other hand, are used in UV-Vis spectrophotometers or fluoro meters to determine the transmission or absorption of radiation at a specific wavelength in the UV and visible range of 190 - 2500 nm.
