Rapid and Reliable 1µL UV-Vis

SmartPath™ Technology

The DeNovix team developed a combination of opto-mechanical components and software algorithms that optimize results for every sample. Bridge Testing™ verification eliminates unreliable results that stem from broken sample columns or loading issues.

  • Quantify DNA, RNA and protein in less than 3 seconds
  • Widest dynamic range and lowest detection limit
    • 0.75 – 37,500 ng/µL dsDNA
  • No routine maintenance or recalibration required
  • Full spectrum UV-Vis analysis using 0.5 – 1.0 µL of sample

SmartPath algorithms ensure that the sample is only compressed, never stretched, to keep the column intact.

SmartQC™ Contamination Alerts

Multiple algorithms ensure confidence in results while also providing important information about possible sample anomalies.

Integrated Fluorescence

Unmatched Sensitivity

The DS-11 Series uniquely integrates an optional 4-channel fluorometer. Fluorescence mode enables up to 1000x more sensitivity. DeNovix Fluorometers are compatible with a wide range of commonly used quantification assays.
