DS-11 FX/FX+ integrated UV-vis-spectrophotometer, fluorometer & cuvette

DS-11 FX, DS-11 FX+ Fire RedThe award-winning DS-11 FX+ from DeNovix combines the most sensitive 1 µl UV-Vis absorbance measurements with the most flexible and precise fluorometer in one compact, maintenance-free instrument. 

Requiring no calibration or maintenance and with the ability to analyse both proteins and nucleic acids, this system is both versatile and exquisitely sensitive. Every compact, easy-to-use instrument is provided with a two year warranty as standard and a great selection of colours to choose from.

What people say about the DS-11 systems
An excellent purchase and many happy customers
“The feedback on the DeNovix spectrophotometers is excellent, several people have reported how pleased they were with the reproducibility, which is so much better than with the NanoDrop™ 1000 we previously had. All in all, an excellent purchase and many happy customers.”

SmartQC™ technology
DeNovix SmartQC monitors the complete measurement and quality control process on the DS-11 microvolume spectrophotometers.

  • Sample contamination alerts
  • Measurement surface cleaning monitor
  • BridgeTesting® - ensures sample column is always formed
  • SmartPath® - always calibrated with no routine maintenance
  • Spectral analysis

SmartQC clearly flags samples that do not meet purity specifications with visual alert icons, providing detailed information regarding the possible reasons for the high or low value. SmartQC detects contaminants such as phenol, proteins, carbohydrates, guanidine, glycogen, nucleic acids and buffers. Highly flexible, SmartQC allows the user to define and save custom limits, to use established default values, or not to enforce any limits.
