The DS-11 and DS11+ integrated microvolume and cuvette spectrophotometers from DeNovix offer sensitive 1 µl UV-Vis absorbance measurements. Requiring no calibration or maintenance and with the ability to analyse both proteins and nucleic acids, these compact, easy-to-use instruments come with a two year warranty as standard and a great selection of colours to choose from.
Also available within the DS-11 range is the award-winning DS-11 FX+, which combines the most sensitive 1 µl UV-Vis absorbance measurements with the most flexible and precise fluorometer in one compact instrument. Find out more about the DS-11 FX+.

DS-11+ cuvette mode
With an additional cuvette mode, the DS-11+ enables up to 10mm pathlength measurements using standard quartz or disposable cuvettes, extending the UV-Vis lower detectable limit. A built-in cuvette heater controls temperature for kinetics studies.
SmartQC™ technology
SmartQC™ monitors the complete measurement and quality control process on the DS-11 microvolume spectrophotometers.
SmartQC™ features
• Sample contamination alerts
• Measurement surface cleaning monitor
• BridgeTesting® - ensures sample column is always formed
• SmartPath® - always calibrated with no routine maintenance
• Spectral analysis
SmartQC™ clearly flags samples that do not meet purity specifications with visual alert icons, providing detailed information regarding the possible reasons for the high or low value. SmartQC™ detects contaminants such as phenol, proteins, carbohydrates, guanidine, glycogen, nucleic acids and buffers. Highly flexible, SmartQC™ allows the user to define and save custom limits, to use established default values, or not to enforce any limits.
DS-11 SmartPath® with Bridge Testing®
Unlike other instruments which must stretch a sample across a 1.0 mm gap, often producing an ‘unbridged’ sample, the DS-11 spectrophotometers work in the opposite direction by compressing samples to a 0.5 mm path during measurement.
Unbridged samples are not uncommon with other microvolume spectrophotometers and this leads to erroneous measurements, without the user knowing about it. With its SmartPath algorithm with Bridge Testing to detect unbridged condition, the DS-11 spectrophotometer software automatically compensates to ensure accurate results.
