Double Beam UV-VIS Spectrophotometer
        The spectrophotometer is an instrument which measures the amount of light of a specificed wavelength which passes through a medium. According to Beers law, the amount of light absorbed by a medium is proportional to the concentration of the absorbing material or solute present. Thus the concentration of a colored solute in a solution may be determined in the lab by measuring the absorbency of light at a given wavelength.  Wavelength (often abbreviated as lambda) is measured in nm.  The spectrophotometer allows selection of a wavelength pass through the solution.  Usually, the wavelength chosen which corresponds to the absorption maximum of the solute. Absorbency is indicated with a capital A
Features
  ※ The innovative optical layout and state of art mono-chromator with high grade blazed holographic grating ensure accuracy. Its integrated design assures long term stability and durability.
  ※ The precisely aligned detector and quality deuterium and halogen lamps enhance the precision across the UV/vis spectrum starting from 190nm and into the near-infrared 1100nm.
  ※ Online software upgrade capability via Internet(for stand-alone models)
  ※ Full A4 print-out of graphs and tables of results with popular inexpensive printers such as HP or Epson Deskjet.
  ※ Real-time clock for date and time stamping of results
  ※ Large LCD display (320*240 Dots Matrix)
