Upgrade to Fluorescence

  • DS-11 can be upgraded to add fluorescence capability with the addition of the FX module.

Microvolume Mode: Smartpath Technology with Bridge Testing

  • SmartPath® Technology is Denovix patent pending design to precisely control microvolume pathlength in real-time. SmartPath® ensures the DS-11 is always in calibration – no drift and no service down-time.
  • SmartPath® technology controls the pathlength in real time ensuring accurate precise measurements. Bridge Testing™ is Denovix propriety process to compress and monitor a sample during measurements to ensure the liquid column is intact. Measurements are accurate and precise for 1µL, even for difficult to measure samples like protein.

Best in Class 1uL Sample Lower Detection Limits!

DeNovix Spectrophotometer 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.

Always Calibrated

  • The DS-11 does not rely on fixed path length calibrations and therefore does not require regular calibration checks. There is no downtime or expense required for routine calibration like many other spectrophotometers. DeNovix offers a LC-NA verification standard for labs that may need to verify proper operation from time to time in accordance with their own quality standards.

 Bridge Testing®

  • DeNovix software includes a proprietary algorithm to test for an unbridged condition in the primary nucleic acid and protein quantification apps. This element of the SmartPath® algorithm not only detects the broken liquid column but compensates to ensure accurate results with no user action required.

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.

Automatic Pathlength Adjustment

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-short pathlengths enable highest abs. measurements

                 0.015 to 750 AU (1 cm equivalent)

                0.75 to 37,500 ng/ml for dsDNA

Ultra High Absorbance

  • 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 37,500 ng/uL of dsDNA. This ultra high absorbance capability is achieved by using a remarkably small path length of 0.02mm enabled by our SmartPath® Technology. Even at this short path length, typical CV of measurements is less than 3%.

Superb Precision

  • 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%.
