DS-11 FX Series of Spectrometer / Fluorometers combine UV-Vis absorbance and fluorescence methods in one compact instrument.

DS-11 FX (1µL UV-Vis, + fluorescence)

DS-11 FX+  (1µL UV-Vis, cuvette UV-Vis + fluorescence)

DS-11+ (1µL UV-Vis, cuvette UV-Vis)

DS-11 (1µL UV-Vis)

- Twice winner of Reviewers’ Choice Product of the Year

- Winner of the prestigious Platinum Seal of Quality

- Winner of the Scientist’s Choice Award for 2018 with the platinum seal of approval


The DS-11 combines the most sensitive 1µL UV-Vis absorbance with the most flexible and precise fluorometer in one compact, maintenance-free instrument.

The DS-11 Series is the first life science instrument awarded the prestigious Platinum Seal of Quality by SelectScience based on scientist reviews for outstanding ease-of-use, performance, service and technical support ( The instrument rapidly quantifies over seven orders of magnitude of nucleic acids and protein samples selecting your choice of UV-Vis or Fluorescent modes. 

The Only All-In-One Absorbance and Fluorescence Design
Equip your lab for today’s quantification requirements and for future assay challenges. The choice of microvolume or cuvette absorbance and fluorescence methods delivers unmatched flexibility and dynamic range. Coupled with the DeNovix dsDNA quantification assays, a range of 0.5 pg/µL to 37500 ng/µL can be rapidly measured.
