J-1500 Circular Dichroism Spectrometer

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.

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.

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 is easily monitored while altering conditions such as temperature, pH, solvent and buffer or binding and rapid kinetics to determine optimize long term stability or otherwise determine the dynamic properties of biomolecules.

This auto-sampling CD system utilized 96 well micro-titor plates for completely unattended measurement of up to 192 samples. Samples are kept at a constant temperature while waiting for 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.

You work hard for your samples and sometimes they are very limited. 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 scale calibration material purity validated using NIST certified standards.

Computerized gas flow modeling was utilized to design the flow of the purge gas to optimize the flow efficiency to purge the fastest and most efficiently throughout the optical system without user intervention.

Only a standard USB2 connection is made between the PC and the CD system assuring that future PC changes are easy to make without concern of compatibility specialized boards placed in 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.
