Fluorometer Mode

  • The highly sensitive QFX Fluorometer is a powerful solution for fluorometric applications. Quantify nucleic acids and proteins using four fluorescent channels and a choice of common assays which are built into measurement apps.
  • Combined with the DeNovix dsDNA quantification 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 is features the most powerful and intuitive software in its class. Pre-installed DeNovix EasyApps® and a breakthrough Android™ 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.

  • Autosave up to 2 million samples.
  • All common quantification assays pre-configured
  • Easily create custom assays

Fluorescence Freedom!
DeNovix fluorometers give scientists the flexibility to choose any fluorescent assay, not just the assays supplied by one manufacturer. Fluorometer apps are pre-configured for common commercially available assays measured in standard 0.5 mL thin-wall PCR tubes. Four fluorescent channels encompass a wide fluorophore excitation (361-662 nm) and emission (435-740 nm) range.

Unrivaled connectivity.
Unlike any other instrument in this class, the QFX is fully network integrated. Built-in Wi-Fi, Ethernet and USB allow easy export of the data you want in the format you need as well as onboard storage of over 2 Million samples.

  • Email a csv or color jpg of your results right from EasyApps
  • Automatically save data to network drives or LIMS
  • Print results or graphs to network and label printers
  • Save to USB

Four color choices

  • Cutting Edge and Tech Savvy– how about the modern Arctic White option for your lab
  • Resourceful and Dynamic – then the brilliant Brazilian Blue fits your style!
