Spectrometer UV-2550 (Shimadzu)
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.
