J-1500 High performance CD spectrometer for versatile measurements





circular dichroism spectropolarimeter

The new JASCO J-1500 is designed to meet the most demanding of CD applications. The performance level is unparalleled and the layout is suited for adaptation to a variety of different sampling methods. With CD, LD and Absorbance provided as standard the base unit is already very capable but when combined with optional measurement modes and sampling accessories in addition to the new Simultaneous Multi-Probe (SMP) acquisition system you can unleash the power only dreamed of by earlier systems.


The Dual Polarizing Prism Monochromator is enhanced for performance into the Vacuum UV region with excellent stray-light rejection for accurate results.

While the UV and Visible performance has been optimized the J-1500 can meet demands well into the NIR region. An optional PMT will extend the range to1250nm and a special detector and light source can be added to extend the range to 1600nm.

Measurement Modes
The wide range of measurement modes available delivers a true chiroptical spectroscopy workbench. One spectrometer can measure CD, LD, Absorbance as standard. Optional modes include Fluorescence, Fluorescence Detected CD, Fluorescence Detected LD, Fluorescence Polarization/Anisotropy, Optical Rotatory Dispersion, Magnetic CD, Stopped flow CD/Abs/Fluorescence and more.

Simultaneous Multi-Probe (SMP)
The SMP technology delivers a new level of productivity that looks at your sample using several techniques at the same time to extract maximal information in minimal time.

CD can be monitored whilst conducting experiments based on temperature, pH, solvent and buffer or for binding and rapid kinetics experiments to determine the dynamic properties of biomolecules.

This auto-sampling CD system utilises 96 well micro-titor plates for completely unattended measurement of up to 192 samples. Samples are maintained at a constant temperature during measurement which can include both spectral and temperature scanning. An adjustable wash cycle is performed between each sample which can be preserved and returned to the micro-plate for further analysis.

Amazing new accessories for the J-1000 allow you to measure excellent CD data from as little as a 5ul sample.

Integrated Hg lamp for wavelength calibration and the first NIST traceable standard for scale calibration assure your results are not only accurate but traceable to internationally recognised standards.

Excellent Nitrogen Purge Efficiency
Computerised gas flow modeling was utilised to design the fastest most optimised purge gas flow efficiency, effective throughout the entire optical system without any user intervention.

USB Interface
A standard USB2 connection is all that is required assuring that future PC changes are easy to make without any compatibility concerns and specialised control boards inside the PC.

Only JASCO CD systems are manufactured to the internationally recognized standards of the ISO quality program assuring you a product which consistently meets guaranteed specifications and a quality level that is defined and unsurpassed.
