While zeta potential alone is often used to make comparisons between materials and formulations, measuring zeta potential as a function of pH, conductivity and other parameters provides much greater insight into the processes involved in disperse systems.

Using the MPT-2 autotitrator, measurements can be made automatically using as little as 2.5 ml sample, allowing the comprehensive analysis of even scarce biological materials. Since all tubing in the sample flow is fully disposable there is no risk of cross-contamination.

Operation is fully automated and protocols can be specified as part of standard operating procedures.
