ZetaPlus

The Brookhaven ZetaPlus is the simplest and most accurate particle electrophoresis system available. This revolutionary instrument has been designed to eliminate the shortcomings inherent in other zeta potential instruments. The ZetaPlus software is simple and intuitive to operate but yet offers flexibility and a full range of means for those who wish to tune their experiments to specific circumstances.

The screen image shown below indicates the clear and concise presentation. Information obtained from the sample is updated in real time and the user can select from several display formats. A Literature of physical constants for many usual suspending fluids is provided but the user may provide his/her values if desired. Printed reports are fully customizable and are provided in color with the supplied printer.
