Ultraviolet-Visible (UV-Vis)


Ultraviolet-Visible Spectrophotometry (UV-Vis):

Ultraviolet and visible spectrometers are a versatile analyzing system almost using in all modern day laboratories. The method is the most common way in quantitative analyzing of an in solution because of its accuracy, simplicity and cost-effectiveness. In brief, when a light direct through a sample including absorbing component in UV-Vis region, a part of molecules called “chromophores” absorb light. These systems calculate the absorbance (A) by measuring a ratio called “transmittance” and using Beer-Lambert law formula (A=log10(Io/I)) . This ratio is the intensity of light directed through a sample called “I” in compare with the intensity of light before it passes through sample of interest “Io”.  


Different models of Ultraviolet-Visible Spectrophotometry (UV-Vis) systems (real double beam model and cost effective dual beam models) for routine and research laboratory works is available in our stock and ready for immediate delivery. Please contact us for further information.
