Cuvettes are small rectangular containers (prisms) with straight sides and a round or square inner section designed to hold liquids,Sealed at the lower end and a stopper at the upper end,They are made of a transparent material such as plastic, glass or quartz.
Cuvettes are designed to hold liquid samples for spectroscopic measurement in a spectrophotometer, a beam of light at different intensities and wavelengths.They are transmitted through the liquid sample as a result of the impact of the light beam on the liquid The light intensity decreases, the detector of the spectrophotometer Detects the intensity of the light and calculates how much it has decreased, from the data obtained it is possible to deduce the properties of the liquid being tested.
Cuvettes are made of transparent materials made of plastic, glass or quartz, because plastic and glass have only visible wavelengths, quartz cuvettes are needed which are more expensive for tests where the wavelengths are invisible-ultraviolet.It is important not to use Cuvettes with solvents, corrosive liquids that may attack the Cuvette and cause it to leak. For such applications Cuvettes with increased chemical resistance are required.
