✔ Three Channel Fluorescence
✔ Stand-Alone (no PC required)
✔ Wi-Fi, Ethernet, USB
Easy to learn. Fast to use. DS-11 FX Series instruments include intuitive, pre-installed DeNovix EasyApps® and a breakthrough AndroidTM touchscreen interface. Every instrument is ready for absorbance and fluorescence measurements right out of the box – no PC set-up or software installation.
Fluorescence Freedom! DeNovix fluorometers give scientists the flexibility to choose any fluorescent assay, not just a specific one designated by a manufacturer. Fluorometer apps are pre-configured for common commercially available assays measured in standard 0.5 mL thin-wall PCR tubes. Three fluorescent channels encompass a wide fluorophore excitation (442-662 nm) and emission (514-740 nm) range.
Microvolume Mode: Always Calibrated. Be confident in 1µL results, even for difficult to measure samples like protein, thanks to SmartPath® Technology. Our patent pending design controls the pathlength in real-time while compressing the sample during analysis. SmartPath® ensures the DS-11 FX is always in calibration – no drift and no service down-time.
Connect to Your Results. Built-in Wi-Fi, Ethernet and USB allows easy export of data you want in the format you need. Email a csv or color jpg of your results…save data to LIMS or network drives…print results or graphs to network and label printers…and more!

Automatic Path Length Adjustment
The DS-11 proprietary SmartPath® Technology in conjunction with DeNovix's innovative microvolume design (patent pending) automatically uses the optimal path length when measuring a sample. Other microvolume spectrophotometers may offer multiple path lengths, but many require the user to guess which path length is needed prior to measuring the sample. The DS-11 uses real-time absorbance data to determine the best path length (ranging from 0.03-0.5 mm) to use for each measurement.
Ultra High Absorbance
The DS-11 can measure samples with absorbance values as high as 500 absorbance units (at a 1 cm equivalent path length). This translates into 750 mg/ml of BSA protein or 25000 ng/ul of dsDNA. (In reality, concentrations this high may be too viscous to measure but the system uses these numbers for reference only). This ultra high absorbance capability is achieved by using a remarkably small path length of 0.03mm (30 microns) enabled by our SmartPath® Technology. Even at this short path length, typical CV of measurements is less than 3%.
Truly 1.0 ul Sample Volumes
A key feature of the DS-11 is that the longest path length used (0.5 mm path) is shorter than the 1.0 mm path used by other microvolume spectrophotometers. This enables the DS-11 to truly measure 1.0 ul samples, virtually eliminating the possibility of erroneous results due to sample column breakage.
The reproducibility of measurements on the DS-11 is an important performance feature. For example, replicates of 500 ng/ul dsDNA samples typically result in CV’s of less than 1%.
No Recalibration Required
By using SmartPath® Technology, the DS-11 does not rely on fixed path length calibrations and therefore does not require regular calibration checks. However, it is good practice to periodically confirm proper instrument operation. DeNovix offers the LC-NA standard to easily verify proper operation of the DS-11.
