UV Spectophotometers PB2201

 

It is an optimal solution of a wide amount of tasks requiring photometric and absorbent analysis method for identification, quantitative test of different organic and inorganic substances and realization of a spectral research in ecological monitoring laboratories, veterinary medicine, pharmaceutical, health and science institutions, in laboratories of a quality control of different economy sectors.

  • Up-to-date analytical spectrophotometers with spectral range from 190 to 1100 nm for working in ultraviolet, visible and near infra-red sectors of a spectrum.
  • Impact xenon lamp with practically unlimited service life is used as one source of light.
  • Work with analyzing samples can be made with an opened cell section.
  • Devices management in an autonomous mode is simplified as much as possible with help of a large graphic display with a sensor panel and friendly interface.
  • It is required to use a PC and particularized software “Spectrum UV-VIS” to enlarge your functional capabilities.

Basic measurement functions

  • Measuring spectrums of absorption and transmission
  • Measuring optical density and transmission
