A spectrophotometer used in laboratories for measuring reflection or transmission properties of any given material. 

  Visible Spectrophotometer Lab Equipment

325 - 1000 nm 4 nm 722N


When creating products made of glass or similar light-transmitting materials, it is very important to measure how transmissive or reflective these surfaces are. The 722N UV-VIS Spectrophotometer serves that exact purpose: to measure reflection or transmission properties of certain materials that are to be used in product creation. This model is used for laboratory purposes, and it is able to measure transmission and reflection of visible light, near-ultraviolet and near-infrared light.

It comes with a compartment for samples that are in between 5 millimeters and 50 millimeters. It has an automatic full scale or zero adjustment, depending on the sample. It also comes with included software and is equipped with an RS232 port.


  • Sample compartment for 5 - 50 mm cells
  • Precise automatic T/A changeover
  • Automatic zero and full scale adjustment
  • Direct concentration read-out and concentration factor setting function
  • Equipped with RS232 port
  • Software included
  • Glass coated, not easily become damp
