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 an intuitive 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.

 

Integrated Absorbance and Fluorescence for unmatched flexibility

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

With the DS-11 Series 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.

Absorbance and Fluorescence quantification are unique but complementary methods for assessing concentration and quality of biological samples. The multi-award winning DS-11 Series of 1 µL Spectrophotometers and Fluorometers provides the most sensitive and widest dynamic range for UV-Vis absorbance and fluorescence capability in one combined instrument.

 

Sensitivity

Extend the lower detection limit for low concentration samples. Quantify down to 0.5 pg/µL dsDNA

Specificity

Selectively quantify your sample in the presence of contaminants using DeNovix Fluorescence Quantification Assays

Total Sample QC

Combine Absorbance and Fluorescence measurements for specific quantification and reliable contamination detection.

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)
