Integrated Spectrophotometer, Fluorometer & Cuvette - DS-11 FX/FX+

Integrated Spectrophotometer, Fluorometer & Cuvette - DS-11 FX/FX+

Winner of the Reviewers’ Choice Award for Life Science Product of the Year 2017 (SelectScience®) and first instrument to receive the prestigious Platinum Seal of Quality 2018 (SelectScience®), the DS-11 FX+ combines the most sensitive 1 µl UV-Vis absorbance with the most flexible and precise fluorometer in one compact, maintenance-free instrument. Requiring no calibration or maintenance and with the ability to analyse both proteins and nucleic acids, this system, when combined with the accompanying dsDNA quantification assays, can quantify between 0.5 pg/µl and 37500 ng/µl. Every compact, easy-to-use instrument is provided with a 3-year warranty as standard and a great selection of system colours can be chosen from.

What People Say About The DS-11 Systems2018 Platinum Award
An excellent purchase and many happy customers
“The feedback on the DeNovix spectrophotometers is excellent, several people have reported how pleased they were with the reproducibility, which is so much better than with the NanoDrop™ 1000 we previously had. All in all, an excellent purchase and many happy customers.”

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 using a 1.0 mm gap that must stretch the sample, potentially producing an unbridged sample, the DS-11 spectrophotometer uses a 0.5 mm path and compresses the sample during measurement. Unbridged condition is a common issue with other spectrophotometers and leads to erroneous measurements, without the user knowing about it.
With the SmartPath® algorithm with Bridge Testing® to detect unbridged condition in the dsDNA, ssDNA, RNA and Protein A280 apps, the DS-11 spectrophotometer software automatically compensates to ensure accurate results, with no user action required.
