UV-2200 Double Beam UV/Vis Spectrophotometer

The UV-2200 UV-Vis spectrophotometer adopts the patented technology of eliminating stray light and the patented technology of the lamp-changing and peak-seeking mechanism. The simple mechanism ensures that the system has sufficient light energy and minimizes the stray light, so that the stray light of the instrument can be avoided. reach the level of less than 1 in 100,000. High-resolution signal acquisition system; high-performance weak-signal program-controlled amplification system, signal processing system composed of multi-stage filters, and high-performance analog-to-digital conversion system and other high-quality electrical systems ensure high stability of instrument operation and high measurement accuracy. 

 

FEATURES

  • Research grade double beam, double monochromator UV/VIS spectrophotometer.
  • Fully PC control measurement with powerful software function and easy operation.
  • Super low stray light, direct determination of high concentration sample, without the need of dilution.
  • Six-step variable spectral bandwidth: 0.1nm, 0.2 nm, 0.5 nm, 1.0 nm, 2.0 nm,
  • Spectrum scan can be made at any wavelength range in 190~1100 nm, with the minimum sampling interval of 0.02 nm.
  • Rich data processing functions, such as spectrum conversion, superposition, derivation, peak-picking, curve smoothing etc.
  • Multi-wavelength determination in photometric mode. User defined arithmetic to the measured data can be made and stored.
  • Various methods for calibration curve establishment in quantitative measurement mode, such as single-wavelength method, double-wavelength method, triple-wavelength method, user-defined methods etc. User-difined method can be saved for the later use.
  • Flexible parameter setting in kinetics measurement mode to perform time scan at a fixed wavelength, with the same data processing functions of spectrum scan.
  • Built-in DNA/Protein module for direct DNA/Protein concentration measurement.
  • Wide sample compartment, to accommodate cell size from 5mm to 100 mm.
