Jasco Circular Dichroism

Circular Dichroism

Chiroptical spectroscopy has become one of the most important techniques for the characterization of biomolecules, determination of absolute configuration and stereochemical analysis. Since launching their first spectropolarimeter in 1961, JASCO has designed and built the finest in chiroptical instrumentation. More than a half-century later, JASCO proudly presents the J-1000 series, their latest circular dichroism spectrometers. Unparalleled optical performance and available measurement modes are combined to make the J-1000 CD spectrometers true state-of-the-art chiroptical spectroscopy workbenches.

Advanced features of the J-1000 series

• High optical throughput
• Low stray light

• Three scanning modes: auto, step and continuous

J-100

J-1100 CD spectrophotometer is a compact, general-purpose space-saving design. This simple yet powerful instrument is perfect for users looking to obtain more routine CD measurements in both industry and academia.

J-1500

J-1500 allows for the maximum flexibility to upgrade your CD system with different measurement techniques. While the standard measurement modes are CD, LD, and absorbance, up to four simultaneous modes can be measured when combined with a wide range of sampling accessories.

J-1700

J-1700 was specifically designed for more demanding near-infrared CD applications. In addition to the enhanced far-UV capabilities, researchers probing the chiral activity of molecules in the NIR spectral region now have the ability to obtain data at wavelengths up to 2500 nm.
