Which model is right for you?

J-1100 CD spectrometer

As the UV/VIS model with measurement range from 180 nm to 600 nm, J-1100 is suitable for the research of biomaterials, such as protein or nucleic acid.

J-1500 CD spectrometer

The high end model of J-1500 with the measurement range from 163 nm to 1600 nm, will answer all the demands for not only the protein, nucleic acid, but also the chiral molecule, super molecule and metal complex.

J-1700 CD spectrometer

J-1700 is high-end model, which has ability to obtain data up to 2500 nm wavelength.
