This device has unique characteristics:

  • The lowest in this class of devices the diameter of the light beam, the resolution to 0.1 nm,
  • The widest in its class photometric range from -4 to 5 Abs.

Double beam optical system ensures stable baseline, and allows the detection of minimal changes in the background, which is very important for colorimetric water analysis.

Spectrophotometer UV-2550 used in various fields of science and industry: organic chemistry, biochemistry, environmental monitoring, textile and food industries.
