Jasco FP-8700 Spectrofluorometer

FP-8700 NIR Spectrofluorometer with a liquid nitrogen cooled PMT detector for applications that require high sensitivity measurements into the near infrared (1700 nm).

The FP-8700 NIR spectrofluorometer is a wide range version of the FP-8600 and includes a choice of two different liquid N2 cooled PMT detectors for greatly enhanced sensitivity in the NIR region to 1400 nm (1700 nm as an option)

Jasco FP-8700 Spectrofluorometer

The FP-8700 is typically used for up-conversion experiments that require on a laser double-photon excitation of an electron. This expanding field is useful for research into some new applications biological dyes and carbon structural analysis. The instrument can be calibrated for quantum efficiency/yield measurements using the calibrated light source with a pattern file correction to 1700nm.

Instrument Performance

  • Highest Sensitivity

    The high throughput optical system and low noise signal processing of the FP-8000 Series provides users with a high S/N (signal-to-noise) performance of up to 5,000:1 (RMS). The advanced A/D converter enables rapid sampling and the high speed signal processing system that immediately converts the fluorescence signal from the detector to a digital signal without introducing any additional noise.

  • Wide Dynamic Range

    A wide dynamic range for luminescence measurements is obtained by using the Auto-Gain and Auto-SCS features, automatically adjusting the detector gain and sensitivity for optimum measurements.


Auto-Gain automatically adjusts the gain of a signal from the detector, so that the S/N is optimized throughout the entire scan range for spectral or time course measurements. Since quantum yield measurements can produce peaks that vary greatly in fluorescence intensity, the auto-gain function assures the accuracy of the measurement.


The Auto Sensitivity Control System (SCS) allows users to create calibration curves for a wide concentration range without having to manually change the instrument Sensitivity settings. Auto-SCS can obtain measurements of sub-picomolar to micromolar concentrations for fixed wavelength measurements and quantitative analyses.

Automatic Band-Pass Filter for Higher-Order Diffraction

The new automatic band-pass filters remove peaks originating from higher-order diffracted light to provide simple and reliable spectral acquisition and analysis. The band-pass filters can also be used for spectral corrections, 3D measurements, and quantum yield determination.
  • Spectral Correction

    JASCO has developed a spectral correction system to provide greater accuracy covering a larger wavelength range. While traditionally Rhodamine B was used for spectral correction of the excitation spectra, the use of calibrated deuterium and tungsten halogen light sources and calibrated detector now provide corrected data which can be directly observed from the UV to NIR spectral regions.
  • Automatic Accessory Recognition

    When an accessory is attached to the instrument sample compartment, Spectra Manager™ automatically recognizes the installed accessory. Previously used instrument parameters associated with the accessory are recalled and information such as the accessory name and serial number are logged with the measurement file information. The IQ start system in conjunction with IQ Accessory recognition allows rapid access to pre-defined analysis methods.

Genetec is a member of the same family of companies as Kovalent. Both companies share the same set of values and are in many ways integrated with each other. The main difference between the two companies are their products. Kovalent is involved in system solutions including instrumentation and Genetec is mainly working with consumables. The focus of Genetec is chromatography accessories. You are welcome to visit their state of the art web shop: genetec.se
