Over what wavelength range would you like to measure samples?
SPECTROPHOTOMETERS
UV/Visible
Often abbreviated to UV/Vis or UV-Vis. UV/Visible spectroscopy offers maximum flexibility and is suitable for applications in the wavelength range of 190 to 1100nm. In UV/Visible spectroscopy the UV region is considered to be any wavelength less than 340nm. Nucleic acid, purified proteins, and other organic molecules are often measured in the UV region.
Visible
Often abbreviated to Vis. Visible spectrophotometers and colorimeters typically measure in the visible region of the electromagnetic spectrum (340-750nm). If your samples are colored this is an indication that they will absorb visible light. If you do not need to measure in the UV region (<340nm) a visible spectrophotometer or colorimeter may be a more economical alternative.
