Duetta™ Spectrofluorometer: Product Description and Specifications

Overview: Duetta™ is a cutting-edge 3-in-1 spectrofluorometer, integrating the capabilities of fluorescence and absorbance spectrometers. It boasts the fastest performance in the market, thanks to its high-speed, built-in CCD detector that can acquire a full spectrum ranging from 250 nm to 1,100 nm in under a second. Utilizing A-TEEM™ technology, Duetta simultaneously measures absorbance, transmission, and fluorescence EEMs while correcting for the inner filter effect in real-time.

Key Features:

• Simultaneous Absorbance and Fluorescence Measurement: Combines fluorescence and absorbance spectrometers in one instrument.
• High-Speed Data Acquisition: Full spectrum acquisition in less than one second.
• A-TEEM™ Technology: Allows simultaneous acquisition of absorbance, transmission, and fluorescence EEMs.
• Accurate Measurements: Single-spot data acquisition without sample movement.
