Introducing the Brookhaven Instruments NanoBrook ZetaPlus

Reliable and Accurate Analysis

The NanoBrook ZetaPlus is the simplest, 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, yet offers a full range of features and options to handle any experimental application. The image shown below is an actual presentation of a measurement- clear and concise. Information obtained from the sample is updated in real time and the user can select from several display formats. A table of physical constants for many common suspending fluids is pre-loaded, but the user has the freedom to provide their own values.

Comprehensive Information

The NanoBrook ZetaPlus measures complete electrophoretic mobility distributions in seconds, including multimodal distributions. An example of a bimodal zeta potential sample can be seen on the result screen after analyis of a mixture of charged particles.

The image to the right is an example of results collected from a measurement on a mixture of alpha and gamma Aluminas in 1 mM KCl and pH 10. The left peak is identified with the green cursor and shown to have a zeta potential of -75 mV. If the other peak is chosen, the zetapotential value is -55 mV. The NanoBrook ZetaPlus has an advantage with its ability to distinguish mixtures such as these, unlike other methods which only provide an average.

Key Benefits

Simple Clear Presentation

With Brookhaven Instruments Particle Solutions Software Suite, the user can easily produce a customized report based on the information desired, or select from one of the pre-designed templates. Furthermore, exportation of data to multiple formats (i.e: XLS, CSV, PDF) is both quick and simple.

Unique Cell Design

The unique cell configuration eliminates the electroosmotic effect: no stationary levels, no alignment, and no calibrations are required. This is evidenced by the excellent agreement with NIST1980, a standard reference
material. NanoBrook ZetaPlus uses low cost, dispoable sample cells. There is no assembly or maintenance required as cross-contamination is eliminated. Glass an quartz cells are available. The same basic cell design is used in the NanoBrook 90Plus Zeta, ZetaPALS, 90Plus PALS, and Omni.
