JASCO J-815 Spectropolarimeter


JASCO J-815 Spectropolarimeter

J-815 is a Circular Dichroism (CD) spectropolarimeter from JASCO. The J-815 is designed to measure CD in the UV/Vis region, and the instrument has two additional measurement modes.


  • Light source: 150 W Xe arc lamp.
  • Wavelength range: 163-900 nm.
  • Standard modes: circular dichroism & UV/VIS absorbance.
  • Optional modes: linear dichroism & fluorescence.
  • Four-channel simultaneous data acquisition: 2 internal and and 2 external channels.
  • Six-position Peltier cuvette holder for temperature-controlled measurements (thermal denaturation and cold effects).

JASCO recommends to use CDPro package for data analysis. It is available for download here. Unzip it to C:\CDPro directory and run index.html file.
