JASCO J-1700 Circular Dichroism Spectrometer

Based on JASCO's experience in CD instrumentation over a half century, the new JASCO J-1700 is a high-performance CD spectrometer. The innovative optical system of the J-1700 allows the measurement of a CD spectrum in the near-IR region up to 2,500nm using a unique Triple Detection system. High sensitivity combined with a maximum of 10,000nm per minute scan speed allows the J-1700 to measure samples quickly increasing productivity. Minimal time exposure of biological samples to the high-energy UV light minimises the risk of sample degradation. 

JASCO J-1700 is ideal for Structural analysis of metal complexes and coloured proteins, Magnetic CD spectra measurements of transition metals and CD measurements of the first and second overtones of vibrational transitions.


In Brief

  • Wide spectral range from vacuum UV to Near IR upto 2500nm
  • High speed scanning 10,000nm/min
  • Extremely low stray light
  • Simultaneous Multi Probe measurements

Installation included

Simplicity and Ease-of-Use

Spectra Manager II or Spectra Manager CFR (For FDA regulated labs): 64 bit innovative, cross-platform Spectroscopy Software Suite for data acquisition, analysis and presentation including several methods of secondary structure calculation.

Excellent optical Performance 

The Dual Polarizing Prism Monochromator covers the entire region required for routine analysis of biomolecules with excellent stray-light rejection for accurate results.

Nitrogen purge capability

Enhanced vacuum UV measurement enables the measurement of a CD spectrum in the vacuum UV region which is of critical importance for biomolecules.

Rapid Scanning and Exceptional Stray Light Rejection

Rapid scanning reduces the time exposure of biological samples to UV light minimising the risk of sample degradation.  Exceptional stray light rejection enables high quality CD data particularly in the Far-UV region where the sample absorbance is high.

Simultaneous Multi-probe measurements

The SMP technology delivers a new level of productivity that looks at your sample using several techniques including CD, Absorbance and Linear Dichroism (LD), at the same time to extract maximal information in minimal time.

Measurement Options

The standard measurement modes include CD, LD and Absorbance for protein, peptides, DNA and other biomolecular studies.

ISO Standard and Validation

JASCO CD systems are manufactured to the internationally recognised standards of the ISO quality program. An integrated Hg lamp for wavelength calibration and the NIST traceable standard for scale calibration assure your results are not only accurate but traceable to internationally recognised standards.

Wide range of sampling accessories with automatic accessory recognition

Options include thermostatted cell holders, cell changers, temperature controllers, microsamplers and specific application software packages.
