Microvolume Spectrophotometer has Broadest Dynamic Range

Denovix Microvolume Spectrophotometer

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, 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.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.
