RAYLEIGH Research UV-2200 DOUBLE BEAM UV/VIS SPECTROPHOTOMETER

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, 0.2nm, 0.5nm, 1.0nm, 2.0nm,
• Spectrum scan can be made at any wavelength range in 190~1100nm, with the
  minimum sampling interval of 0.02nm.
• 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.
  y Wide sample compartment, to accommodate cell size from 5mm to 100 mm.
