*An erroneous measurement can occur if an insufficient sample volume is pipetted for the microvolume measurement. In addition, many microvolume spectrophotometers, such as the NanoDrop 2000, 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 NanoDrop 2000 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 path gap and automatically compensates for the issue in real time.

Summary

The next generation DeNovix DS-11 introduces new features to the microvolume spectrophotometer market, providing more confidence for a broader range of sample types and sample concentrations.
