QFX Fluorometer

Powerful Quantification

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 QFX outperforms Qubit^® 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 for Greater Assay Choice

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!

DeNovix fluorometers give scientists the flexibility to choose any fluorescent assay, not just the assays supplied by one manufacturer. Fluorometer apps are compatible with DeNovix Fluorescence Assays and other common commercially available assays measured in standard 0.5 mL thin-wall PCR tubes. Assays include:

dsDNA: DeNovix dsDNA Broad Range, DeNovix dsDNA High Sensitivity, DeNovix dsDNA Ultra High Sensitivity, Quant-iT PicoGreen® , Quant-iT dsDNA HS, Quant-iT dsDNA BR, Qubit®dsDNA BR, Qubit®dsDNA HS, Quantifluor dsDNA and Quantifluor One dsDNA

RNA: DeNovix RNA Assay, Quant-iT Ribogreen, Quant-iT RNA BR, Quant-iT RNA HS, Qubit® RNA BR, Qubit® RNA HS, Quantifluor RNA, Quant-iT microRNA, Qubit® MicroRNA

ssDNA: Quant-iT OliGreen, Qubit® ssDNA, Quantifluor ssDNA

Protein: Quant-iT Protein, Qubit® Protein

Unrivaled Connectivity

Unlike any other instrument in this class, the QFX is fully network integrated. Built-in Wi-Fi, Ethernet and USB allow easy for export of the data you want in the format you need. The QFX also has onboard storage capacity for over 2 million samples.
