DS-C Cuvette Spectrophotometer

Cuvette Quantification Made Easy

The DeNovix DS-C is an easy-to-use UV-Vis cuvette spectrophotometer with outstanding dynamic range, sensitivity and flexibility. Rapidly quantify biomolecules using any cuvette with an 8.5 mm z-height. The instrument includes preinstalled EasyApps for nucleic acids, proteins, colorimetrics assays, OD600, Kinetics, Custom Methods and more.


Easy to Learn. Fast to Use.

The DS-C features the most powerful and intuitive software in its class. Pre-installed DeNovix EasyApps™ software and a breakthrough Custom Linux™ OS touchscreen interface ensure error-free operation and sample results under 2 seconds. Every instrument is ready right out of the box.

  • Autosave millions of samples.
  • Common quantification assays pre-configured
  • Easily create custom assays
  • Compatible with a wide range of quartz and disposable cuvettes

Unrivaled Connectivity and Storage.

Built-in Wi-Fi, Ethernet and USB allow easy export of the data you want in the format you need. 32 GB of memory allows storage of millions of results!

  • Email a csv or color jpg of your results right from EasyApps
  • Automatically save data to network drives or LIMS
  • Flexible export to easily rename and save the fields you desire
  • Print results or graphs to network and label printers
  • Save to USB



Create simple kinetics methods measuring two absorbance wavelengths over a user-defined measurement frequency and period.  EasyApps streamlines the process to create and save custom methods and enables cuvette temperature control between and 37° and 45° C.


Cell Culture OD 600

The high-particulate nature of bacterial cell cultures benefit from a longer measurement pathlength. The particulates in these samples scatter light, and a 10mm pathlength provides a longer cross-section of the sample for the spectrophotometer’s light beam to travel through. This ensures the highest degree of accuracy and reproducibility when measuring these types of samples.
