Powerful, Sensitive Fluorescence Quantification

The QFX Fluorometer is more sensitive and reproducible than any other instrument in its class.

Why Do Scientists Choose the QFX Fluorometer?

The DeNovix QFX Fluorometer offers the widest dynamic range, greatest sensitivity, and ground-breaking ease of use. The QFX includes four excitation sources and requires as little as 1 μL of sample. The system is compatible with DeNovix dsDNA and RNA Fluorescence Quantification assays, commonly used Thermo Fisher Qubit™ assays, or user-configured custom assays.

Intuitive, Affordable and Broadest Dynamic Range

The QFX Fluorometer is more sensitive and reproducible than any other instrument in its class. The QFX is a powerful solution for all fluorometric applications where enhanced specificity or sensitivity are needed. Quantify nucleic acids and proteins using four user-selectable fluorescent channels with a choice of common assays or easily create custom apps for the ultimate in fluorometer flexibility. The DeNovix QFX Fluorometer outperforms the Thermo Fisher Qubit™ fluorometer and other tube fluorometers, giving superior data quality, more powerful software, and full network integration for seamless data handling.

Combined with the DeNovix Fluorescence Assays, the QFX offers quantification of DNA between 0.5 pg/µL and 4000 ng/µL. The ideal solution for quantification of degraded or low concentration samples, even in the presence of common contaminants.

 

Easy to Learn. Fast to Use.

The QFX features the most powerful and intuitive software in its class. Pre-installed DeNovix EasyApps™ and an intuitive touchscreen interface ensure error-free operation and sample to data in under 2 seconds. Every instrument is ready right out of the box – no PC set-up or software installation required.

  • Autosave up to 2 million samples.
  • Four user-selectable fluorescent channels
  • Compatible with all common quantification assays
  • Easily create custom assays

Four User-Selectable Fluorescent Channels for Greater Assay Choice

channels_table
DeNovix Fluorometers include four user-selectable emission and excitation channels to provide scientists the flexibility to use the fluorophore and detection ranges of your choice. Choose from UV (375 nm), Blue (470 nm), Green (525 nm) or Red (635 nm) excitation sources.

Fluorescence Freedom!
