Zetasizer Nano Series - Specification

 

"Although we’ve had the Zetasizer Nano only since November last year, it is clearly proving to be the easiest to use and most reliable of all the light scattering systems we’ve had in the lab. Whether sample concentration is low or high, it is never a problem, and is all taken care of with a single button, fully automated measurement. Data are clean and easy to interpret. Whereas light scattering systems we’ve used previously have proved too sensitive to contaminating particles, this is overcome with the Zetasizer Nano."
