Product Description

Horiba Spectro Fluorescence Duetta

Ultra fast compact spectrofluorometer for analytical molecular fingerprinting
From the global leaders in fluorescence comes a new bench-top instrument and a new concept for analytical molecular spectroscopy.

A Superior Spectrometer Concept

The Future of Fluorescence

  • Two-in-one Fluorescence and Absorbance Spectrometer
  • UV-Vis-NIR Fluorescence Detection Wavelength Range from 250 to 1,100 nm
  • Full 3-D Fluorescence EEM Acquisition in Less Than One Second
  • Best in Class Fluorescence Sensitivity Specification of 6,000:1 RMS for Water Raman
  • Automatic Correction for Primary and Secondary Inner Filter Effects (IFE)
  • High Fidelity Molecular Fingerprinting with Unique A-TEEM™(Absorbance-Transmittance Excitation Emission Matrix) Technology
  • Millisecond CCD Detection of Entire Fluorescence Spectrum

Fluorescence and Absorbance in one Spectrometer!

Duetta can be used as a fluorometer, as a UV-Vis-NIR spectrometer to measure absorbance, or as an instrument that measures true molecular fingerprints, which require the acquisition of fluorescence and absorbance, correcting for IFE in real time.

Fluorescence in the Blink of an Eye!

Duetta’s ultra-fast, state-of-the-art CCD technology allows it to outperform, by orders of magnitude, any competitor using PMTs. It’s the fastest bench-top fluorometer in the world, and the only fluorometer that can acquire a full spectrum in less than 100 milliseconds! This state-of-the-art CCD technology also extends NIR wavelength detection to 1,100 nm, well beyond the limit of a standard PMT fluorometer.

Highest Fluorescence Sensitivity in its Class

Having the highest level of fluorescence sensitivity means that Duetta’s optimized design lets you measure lower concentrations of a sample, and provides better quality data.

EzSpec™ Touch-Screen Software!

Duetta debuts HORIBA’s new generation software interface with touch-screen utility, and a selection of Apps for routine analysis.

A New Spectrometer Design

Fluorescence and Absorbance

Duetta’s two specialized sample detectors collect fluorescence at right angles to the excitation light, and absorbance straight through the sample.

Absolute Fluorescence Spectra with Real Time Inner Filter Effect (IFE) Correction

IFE limits the linearity of the fluorescence signal at higher sample concentrations due to primary and secondary re-absorption of fluorescence. Duetta’s unique design applies real time IFE correction to obtain absolute fluorescence spectra at higher sample concentrations.

CCDs Collect the Entire Emission Spectrum

Ergonomic, Hands Free, Sample Access

Duetta’s CCD detection takes a snapshot of the entire fluorescence emission spectrum from 250 to 1,100 nm. (So not only is it much faster but it also gives you much more information than the competition.)

Extended NIR Wavelength Range up to 1,100 nm

Near Infrared applications are growing rapidly, and Duetta is ready to meet the challenge with fluorescence detection from 250 to 1,100 nm, well beyond the reach of standard PMTs.

Easy Lamp Cartridge Replacement Lamp

Lamp cartridges are pre-aligned at the factory, guaranteeing perfect alignment upon snap-in replacement. No tools or service are required.

Smart Sample Accessory Trays

Switching from one type of sample holder to another could not be easier.

Without any tools or cables, Duetta’s spill-proof sample accessory trays are identified by EzSpec software, enable electrical power for the appropriate module (e.g. 4-position Peltier holder), and read an enabled
sensor (e.g. temperature), if available.

Fully Automated Order Sorting Filters

Duetta includes excitation and emission cut off filters for automated elimination of second order grating effects, which otherwise interfere with the fluorescence signal of interest.

EEMs Acquired in Seconds
Excitation Emission Matrix (EEM) acquired in 1 second, shows no second order scattering.

Pyrene in a solution of A-B-A triblock copolymer micelles is solvated in the hydrophobic core solvent environment. 3D EEMs can be shown in contour, waterfall plot, or 2D overlay mode.

Biology and Biochemistry

BSA protein measured from 5° C to 60° C and the peak intensity and peak wavelength are plotted vs. temperature of the protein solution. Measured using the SampleSnap-4Pelt 4-position Peltier temperature-controlled cuvette holder.


Polymer Aggregation and Structure. Temperature dependent spectra showing polymer micellization.

Molecular Binding (FRET)

A. Kinetic spectral scans of native BSA protein with rapidly added ANS (3×10-6 M). Spectra taken every 100 ms after ANS addition. As ANS binds to native BSA, the BSA Trp emission decreases and the ANS emission increases as a result of FRET due to proximity of excited Trp and ANS.
B. Kinetic spectral scans of SDS-denatured BSA after addition of ANS. Much higher ANS concentration (4×10-5 M) is required to affect binding to enatured BSA; no FRET is observed due to increased distances between ANS and Trp.

Rare Earths

Emission spectra of a series of glass materials containing different lanthanides. Measured using the SampleSnap-Uni solid sample holder.

Protein Biophysics

Comparison of bovine serum albumin protein and the same protein denatured by sodium dodecylsulfate (SDS). The emission peak narrows and shifts 15 nm to the blue.


Quenching: Fluorescence monitoring of the titration of 1 M potassium iodide (KI) into a solution of 2-aminopyridine, a common small molecule drug pre-cursor.
