Award Winning Performance


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 Only All-In-One Microvolume and Cuvette Absorbance with Fluorescence Design

With the DS-11 FX+ you can equip your lab for today’s quantification requirements and for future assay challenges. Combine the ease of use, wide dynamic range and contamination information of UV-Vis with the enhanced sensitivity and analyte-specific quantification of fluorescence for total sample quality control.

The choice of microvolume and cuvette absorbance plus fluorescence methods delivers unmatched flexibility and dynamic range. Coupled with the DeNovix dsDNA quantification assays, a range of 0.5 pg/µL – 37500 ng/µL can be rapidly measured.


Best in Class 1 uL Sensitivity and Highest Absorbance Capability

DS-11 Series Spectrophotometers set the industry standard for the lower detection limits of 0.5 -1.0 uL UV-Vis sample analysis. Detect to 0.75 ng/uL dsDNA, 0.60 ng/uL RNA or 0.04 mg/mL BSA.  The DS-11 can measure samples with absorbance values as high as 750 absorbance units (at a 1 cm equivalent path length). This translates into 1125 mg/ml of BSA protein or 37500 ng/uL of dsDNA. This ultra high absorbance capability is achieved by using a remarkably small pathlength enabled by our SmartPath® Technology.


Easy-to-Learn, Fast-to-Use

The DS-11 Series instruments feature the most powerful and intuitive software of its type. EasyApps® software is designed by life scientists and combines with a breakthrough Android™ touchscreen interface to ensure error-free operation and sample to data in under 4 seconds. Every instrument is ready to go right out of the box – no PC set-up or software installation required.

Multiple Model and Color Choices

The DS-11 Series is available in 4 models with different combinations of microvolume absorbance (M), cuvette absorbance (C) and Fluorescence (F):

  • DS-11 FX+ (M/C/F)
  • DS-11 FX (M/F)
  • DS-11+ (M/C)
  • DS-11 (M)

All models are available in multiple colors (red, white, blue and silver)
