DeNovix DS-11 Spectrophotometer Advantages vs. Thermo Fisher NanoDrop™ 2000 Spectrophotometer

Thermo Scientific NanoDrop™ 2000 spectrophotometers are used to measure nucleic acid and protein samples in small volumes, typically 1µL. The term “NanoDrop™” has become synonymous with the type of spectrophotometry, but the Thermo Fisher NanoDrop™ 2000 spectrophotometer does not offer comprehensive advantages over all other microvolume spectrophotometers.

The DeNovix DS-11 Spectrophotometer is a compact, stand-alone spectrophotometer with some of the best-in-class features and advantages. It outperforms the Thermo Fisher NanoDrop™ 2000 spectrophotometer from the perspective of accuracy, convenience, performance, reliability and more.

Technical Note 125 is a direct comparison of key features of the DeNovix DS-11 Spectrophotometer versus the Thermo Fisher NanoDrop™ 2000 spectrophotometer. Browse the table below for a full breakdown of which instrument comes out on top in key performance areas.

*An erroneous measurement can occur if an insufficient volume is pipetted when using systems that stretch a sample between two measurement pedestals. DeNovix SmartPath™ technology eliminates this through sample compression, setting the optimum pathlength for each sample. In addition, many microvolume spectrophotometers, such as the Thermo Fisher NanoDrop™ 2000 spectrophotometer, can exhibit a phenomenon referred to as “unconditioning.” This is when the surface loses its hydrophobic property, and droplets spread out instead of beading up. The Thermo Fisher NanoDrop™ 2000 spectrophotometer does not alert the user to a broken column and allows erroneous measurements to go undetected. The DS-11 SmartPath technology detects if a sample does not fully bridge the gap and automatically compensates for the issue in real time.
