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

The Only All-In-One Absorbance and Fluorescence Design

Equip your lab for today’s quantification requirements and for future assay challenges with the only all-in-one system combining microvolume absorbance and fluorescence. 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.

Total Measurement Confidence The patented (Patent US9442009 – Apparatus and Method for Making Optical Measurements of Samples) DS-11 FX combines unique hardware and software features to deliver unmatched confidence in sample accuracy, performance and reliability.

  • SmartPath® Technology – real-time, precise pathlength control delivered every time
  • Exceptional for proteins – BridgeTesting® eliminates broken sample columns common on other platforms 
  • Calibration and maintenance-free – no measurement drift, no service down-time. Accurate results every time. 
  • Industry-leading 3-year warranty

Contamination Alerts

SmartQC monitors every sample measured for the presence of common contaminants, highlights these samples to the user and advises on potential issues. SmartQC also solves the problem of samples being left to dry on the measurement surface by monitoring the sample measurement and cleaning process and warning when the sample has not been removed.

Easy to Learn, Fast to Use

The DS-11 FX 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 for absorbance and fluorescence measurements right out of the box – no PC set-up or software installation.

Fluorescence Freedom!

The most sensitive and precise fluorometer of its type provides the ability to run almost any common fluorescence assay. Choose from a wide range of pre-configured kits or create custom applications for total flexibility. Combine the DS-11 FX with the DeNovix dsDNA fluorescence quantification kits for industry-leading sensitivity and dynamic range. Quantify to 0.5 pg/µL up to 4000 ng/µL with our choice of three quantification kits. 

Unmatched connectivity

Built-in Wi-Fi, Ethernet and USB allow easy export of data you want in the format you need. Email a CSV or color jpg of your results right from EasyApps…save data to LIMS or network drives…print results or graphs to network and label printers…and more! 

FX series Spectrophotometer / Fluorometers are available in four colors and two models:

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