The NanoPlus AT is used to titrate sample suspensions in a pH range from 1 to 13. The instrument automatically controls the pH of these suspensions and conducts titrations during both zeta potential or nano particle size analysis measurements.


  • Automatic unattended operation
  • Automatic determination of isoelectric point
  • Software control of the titration and measurement provides automatic control through standard operating procedures
  • Automatically generated reports and graphs – plot size and zeta potential vs. pH value and additive volume

As the pH value of a solution changes frm acidic to alkaline, alumina particles show a significant change from plus to minus zeta potential values.
