SPECORD 210 PLUS UV/Vis spectrophotometer

SPECORD PLUS series UV-VIS spectrophotometers DOUBLE-BEAM SPECTROPHOTOMETERS

Real double-beam spectrophotometer with monochromator variable slit width (0.2/0.5/1/2/4 nm), dual thermally stabilized CСD detector and control via PC.

SPECORD spectrophotometers actually perform as a freestanding brand, which for 50+ years stands out all over the world for its absolute design reliability and measuring accuracy. The instruments feature unparalleled functional capabilities and supreme quality. The double-beam structure of the optical system combined with two thermostatted CCD detectors ensures high reproducibility and stability of measurement results over over time.

Main advantages:

  • monochromator with concave holographic grating and reduced stray light;
  • minimal quantity of moving parts in the optical system ensures reproducibility, vastly improved signal-to-noise ratio and high concentration of radiation energy;
  • aspheric optics for optimized, precise spectral imaging;
  • pre-adjusted and voltage stabilized radiation sources;
  • Integrated holmium filter for automatic wavelength calibration, for precision and reproducibility of wavelength setting;
  • maximum lamp service life;
  • double-beam design of the optical system to ensure high accuracy of results – simultaneous measurement of the working and reference signals;
  • ability to vary the wavelength resolution value enables to view all the spectral features;
  • position of the second cell right in front of the detector permits analyzing turbid samples.
  • improved detection system – two thermostatted CDD detectors to ensure stability of results over time.
