DeNovix takes spectrophotometry to a whole new level of performance with the DS-11 Series. This easy-to-use, compact instrument delivers full spectrum UV-Vis analysis and fluorescence capability making it ideal for rapid nucleic acid and protein quantification. Our customers agree and have made the DeNovix DS-11 Series the 2017 and 2018 Reviewers’ Choice Product of the Year and the first life science instrument to be awarded the Platinum Seal of Quality by SelectScience based on scientist reviews for outstanding ease-of-use, performance, service and technical support.

The DeNovix DS-11: The Most Sensitive Microvolume Spectrophotometer

The patented (Patent US9442009 – Apparatus and Method for Making Optical Measurements of Samples) DS-11 takes spectrophotometry to a whole new level of performance and reproducibility. This easy-to-use, compact instrument delivers full spectrum UV-Vis analysis and is ideal for rapid nucleic acid and protein quantification. Simply pipette and measure. It’s that easy!

Total Measurement Confidence

The DS-11 combines unique hardware and software features to deliver unmatched confidence in sample accuracy, performance and reliability

  • SmartPath® Technology – real time, precise pathlength control delivered every time
  • Exceptional for proteins – BridgeTesting® eliminates broken sample columns common on other platforms
  • Contamination Alerts – Instant sample QC guidance
  • Calibration and Maintenance Free. No measurement drift, no service down-time. Accurate results every time.
  • Industry-leading 2-year warranty.

Easy to learn. Fast to use.

DS-11 instruments feature the most powerful and intuitive software of its type. Designed by life scientists, pre-installed EasyApps® delivers error-free operation and sample to data in under 4 seconds. Every instrument is ready to measure right out of the box – no PC set-up or software installation

DS-11+ Cuvette Mode

Enables up to 10mm pathlength measurements using standard quartz or disposable cuvettes extending the UV-Vis lower detectible limit. The built-in cuvette heater controls temperatures for Kinetics studies.

Connect to Your Results.

Built-in Wi-Fi, Ethernet and USB allows easy export of data you want in the format you need. Email a csv or color jpg of your results, save data to LIMS or network drives, print results or graphs to network and label printers and more!

Upgrade to Fluorescence

To take advantage of enhanced sensitivity and specificity, the DS-11 can be upgraded to add fluorescence capability with the addition of the FX module. Alternatively, the DS-11 FX Series integrates both microvolume, cuvette absorbance and fluorescence into one compact instrument.

The optional FX Fluorescence Module enables any DS-11 to also function as a highly sensitive fluorometer.
