The DeNovix DS-11 FX+ Spectrophotometer/Fluorometer is designed to measure the concentration and purity of nucleic acids (DNA, RNA) and proteins, as well as quantify fluorescence assays.


  • Dual-Mode Operation: The DS-11 FX+ combines both absorbance (for spectrophotometry) and fluorescence (for fluorometry) detection modes in a single instrument. This versatility allows researchers to perform multiple types of analyses without needing separate machines.
  • Wide Range of Applications: It can quantify and analyze DNA, RNA, proteins, and other biomolecules. For DNA and RNA, it can assess concentration, purity, and sample quality. It can also perform assays involving fluorescent dyes, such as protein quantification or cell-based assays.
  • Microvolume Measurements: One of its notable features is the ability to measure samples in very small volumes (typically in the microliter range). This can be beneficial when working with limited sample volumes, as it reduces sample waste.
  • User-Friendly Interface: The instrument often comes with user-friendly software that simplifies data analysis and operation. This makes it accessible to researchers with varying levels of expertise in spectroscopy.
  • Accuracy and Precision: The DS-11 FX+ is known for its accuracy and precision in measurements, providing reliable data for research and analytical purposes.
  • Connectivity and Data Handling: Allows data transfer to computers or other devices for further analysis and storage.
