- Determine isoelectric point with acid/base or reagent titration.
- Optimize surfactant concentration.
- Measure effect of salt concentration (ionic strength) on zeta potential.
The BI-ZTU autotitrator option for the NanoBrook zeta potential analyzers is ideal for automatic determination of the isoelectric point (IEP) of colloidal materials.
The BI-ZTU Autotitrator option for the NanoBrook zeta potential analyzers is ideal for automatic determination of the isoelectric point (IEP) of colloidal materials. Four pumps provide unparalleled flexibility for optimizing reagent use. The dramatic savings of reduced labor costs allows for larger scale studies that produce more valuable results.
In addition, the BI-ZTU can be used to evaluate the effect of salt concentration on zeta potential. Also, the surfactant costs can be minimized. Use the BI-ZTU to find the minimum concentration at which the zeta potential does not significantly change.
The BI-ZTU Autotitrator is simple to set up and to use:
When the BI-ZTU option is added to a NanoBrook zeta potential instrument, the titrator command appears in the main menu bar. The software automatically guides the user through an autotitration experiment. User friendly dialog boxes guide even the inexperienced operator through each step.
