J-815 Circular Dichroism Spectropolarimeter

circular dichroism spectropolarimeter

 

 

The J-815, the World's most comprehensive Chiro-optical Spectrometer is still the most sensitive!

circular dichroism spectropolarimeter

J-815 Spectropolarimeter    Circular Dichroism, UV/Visible,  Fluorescence,  NIR research-grade chiroptical spectrometer.

  • Precision optics offers a parallal collimated beam to ensure accurate results regardless of sample cell dimension and position relative to source and detector - essential for sampling techniques where scatter is a problem or for accessories such as MCD
  • Measurement from 163-1100 nm with highest S/N ever achieved
  • Traceable Calibration for IQ, OQ,PQ for GLP/GMP regulated labs. Traceable standards for wavelength, absorbance and CD signal
  • 21 CFR Part II compliant software for electronic signature
  • New auto-response measurement optimizes instrument response to scan speed and signal
  • Auto-scale mode for data acquisition
  • Remarkable stability eliminates need for frequent calibration
  • Extremely low stray light (better than 0.0003%) ensures accurate, reproducible CD data into the Far UV
  • Compact, air-cooled 150W xenon arc source with option for the massive luminous output, water cooled 450 watt light source
  • Spectra Manager II and Spectra Manager CFR software for Windows XP Pro

Measure:

  • Circular Dichroism/ UV/Visible absorbance
  • Linear Dichroism/ Oriented molecules
  • Fluorescence detected CD and Total Fluorescence
  • Magnetic CD - permanent and electromagnets
  • Optical Rotation Dispersion
  • Fluorescence
  • Stopped Flow CD
  • Stopped Flow Fluorescence and absorbance

Want to squeeze as much information as possible from your precious sample? Why not use your CD instrument to do several jobs for you! The J-815 configured with the PFD-452S Peltier cell holder, FMO-427 EM Monochromator, Titrator and Macro software will enable acquisition of CD data simultaneous with Fluorescence data during thermal melts and chemical denaturation studies.


Increased Performance

JASCO has worked very hard to squeeze the very best out of the J-815's optical bench. We still use the proven design of dual prism optics, but a new 150 watt air cooled lamp housing provide remarkable stability and low maintenance cost. The power supply is fully integrated to save bench space - the J815 takes the same bench space as an any advanced UV-Vis spectrophotometer.

The J-815 has class leading optical performance.

  • Baseline stability
  • Signal to noise and drift even at the far UV
  • Precision and Accuracy

are unequalled and unsurpassed even by water cooled 450 watt instruments like the renowned J-720!

 

 

 

Features

  • Light source: 150W Xe arc lamp (air cooled) or 450W Xe arc lamp (water cooled)
  • Sample chamber: small or large - designed for your experimental techniques, with the collimated beam you can even make out of compartment measurrement without sensitivity drop!
  • Wavelength range: 163 ~ 900 nm (standard) ~1100 nm (with optional NIR sensitive PMT)
  • Four Channel Simultaneous Data Acquisition: Input channels: 2 internal plus 2 external signals can be acquired simultaneously
  • SIngle position and six cell peltier cell holders for temperature controlled simultaneous CD and fluorescence measurements
  • New Spectra Manager Software - Experiment design and data management software is JASCO's new, Spectra Manager system running on Windows XP/2000 with MacroManager
  • Safety interlocks for lamp operation and nitrogen supply protects the instrument from operator error
  • Validation systems (and software) for GLP/GMP and regulatory compliance  


Powerful Experimental Design

Using the single or six position peltier temerature thermostatted cell holder, you can design experiments to monitor any aspect of protein folding. The optional side entry port allow the simultaneous measurement of total fluorescence or fluorescence detected CD FCD.

Titrations can be automatically controlled using the automatic titrator with control by Macro Manager to design your own custom experiments.

The addition of a Biologic SFM-20 or one of the other Biologic units can add the facility to perform rapid kinetics or quench flow experiments.

The 4 channel insterface means that you can acquire much more data than before, you just need to design the experiment to make the most of this new flexible system!


Data

Spectra Manager ™ II and Spectra Manager ™ CFR

Jasco is the first instrument manufacturer to offer a powerful 32 bit Windows® software platform for control of it's full range of spectroscopy instrumentation as well as complete analysis and display of any kind of spectral data. Spectra Manager is an innovative approach to a cross-platform package setting a new standard for ease of use and allowing users to work seamlessly between several different types of instrumentation. Spectra Manager CFR includes all the features required to comply with FDA 21CFR11 requirements.

  • Compatible with Windows XP and 2000
  • Simple to use Windows Interface even for complex experimental design using MacroManagerTM 
  • Report results in all the major data formats including Molar Ellipticity, Millideg etc.
  • Secondary structure can be analysed by our own or any of the data packages available, even over the internet (see the excellent Dichroweb service offered by  Prof. B.Wallace at Birkbeck College)


Other new features

Easier operation through greater PC control of instrument facilities such as

  • Shutter to protect UV labile samples
  • N2 purge gas control including alarm on Nitrogen failure
  • PMT HT setting during manual measurements and light source power on/off 
  • Compact design - small footprint not much larger than a conventional UV-vis spectrophotometer
  • built-in light source power supply
  • Other: Sample chamber liquid leakage sensor, liquid leakage stop valve (optional)
