From low concentration protein solutions to emulsions, colloids and suspensions, the DelsaNano can measure particle size and zeta potential in most cases without the need to dilute the sample. Sample cells for both aqueous and non-aqueous liquids optimise the measurement process and a special surface analysis cell is available to measure the zeta potential of surfaces such as films and membranes. Flexible enough for detailed research work and using it's SOP operating structure, simple enough for routine QC work, the DelsaNano provides reliable reproducible data quicky and easily. An optional Auto titrator allows up to 3 additives to be titrated for Ioselectric point determinations and to monitor surfactant effectiveness.
