The J-1000 Series Circular Dichroism spectrophotometers are specifically designed for high sensitivity measurements in the near- and far-UV regions, for scientists that need confidence in the data from characterization studies of biomolecule structure, function, and stability under a wide variety of experimental conditions.

Unlike some detectors which only provide good signal-to-noise for low absorbing materials, the J-1000 Series circular dichroism spectrophotometers use high dynamic range detectors to obtain high-quality spectra of samples with excellent signal-to-noise, especially for highly absorbing materials found in the far-UV.

Features of the J-1000 Series

  • High optical throughput
  • Double prism monochromator providing low stray light
  • Wide dynamic range PMT detector
  • Highly efficient nitrogen purge system
  • Digital signal processing
  • Simultaneous Multi-Probe: CD, LD, HT, DC, absorbance, fluorescence
