Zetasizer Nano Cells

Unique maintenance-free cell
One of the most exacting challenges in zeta potential measurement is to ensure the complete cleanliness of the sample cell. Even the smallest amount of contamination can dramatically affect the measured zeta potential. This problem has been solved in the Zetasizer Nano series with the development of a unique entirely disposable cell that consists of electrodes and a folded capillary, molded into a single precision measurement chamber. The cell can be discarded after a single measurement or series of experiments, or re-used where cleaning procedures are known to be effective for the application.

The folded capillary cell is central to the design and use of zeta potential measurement in the Zetasizer Nano series. Additionally, its suitability for particle size measurements allows both size and zeta potential to be measured.

Universal Dip Cell
This reusable cell can be used for zeta potential measurement in non-aqueous applications and is especially important where there is chemical incompatibility between the sample and the disposable cuvettes. The universal cell and measurement sequence have been designed to be suitable for both non-aqueous and aqueous dispersants.
