The DeNovix DS-11 Series of Spectrophotometer/Fluorometers and the Thermo Fisher NanoDrop™ One spectrophotometer are both used to perform fast quantification of nucleic acids and proteins. The spectrophotometer/fluorometer range from DeNovix provides superior limits of detection, the widest dynamic range, an easy-to-use interface and powerful networking features, which surpass the capabilities of the Thermo Fisher NanoDrop™ spectrophotometer. Here we will here we will outline the difference between the DeNovix DS-11 FX Spectrophotometer/Fluorometers and the Thermo Fisher NanoDrop™ One spectrophotometer.
Developed by the Creators of Microvolume UV-Vis
The DS-11 was first introduced to the market in 2013, and was the first UV-Vis spectrophotometer in the world with a customized operating system, touchscreen control and be network-connected.
Over the years, DeNovix has expanded the instrument’s features and functionality by collaborating with the Life Science community. The DS-11 Series also includes a fluorometer mode option with higher sensitivity capabilities integrated into the system. The DS-11 FX+ is patented (US9442009) and offers outstanding limits of detection for fluorescence quantification (0.5 pg/μL dsDNA) and microvolume absorbance (0.75 – 37,500 ng/μL dsDNA).
In just one unit, labs can choose the integrated model that fits both current and future research needs with the combination of fluorescence detection, microvolume UV-Vis and cuvette UV-Vis. All DS-11 Series instruments come with a two-year factory warranty from DeNovix.
