Improved Versatility for Malvern's Zetasizer Nano Particle Characterization System

The new ZEN1010 high concentration zeta potential cell for the market leading Zetasizer Nano particle characterization system from Malvern Panalytical enables measurement in samples of up to 40% w/v. The design, which incorporates a reduced optical path length, can typically provide three times the concentration measurement ability of standard cells for a particular sample.

High concentration zeta potential cell for the Malvern Panalytical Zetasizer Nano.

Suitable for measurement in aqueous media, the new cell takes just 150?l sample in the measurement area. As a consequence of the reduced optical path and reduced measurement volume area, there is less heat generation than in conventional cells making the ZEN1010 highly suitable for delicate samples, including biological materials such as proteins.

Although it operates just like a standard cell on the Zetasizer Nano, the ZEN1010 allows robust zeta potential measurements in highly concentrated samples. By requiring less sample dilution, it supports improved maintenance of the pH and chemical structure of the sample, for more directly relevant zeta potential measurement. This is especially important in many colloidal materials, where measuring the sample in its native state avoids the need for the often complicated centrifugation and dilution procedures needed to maintain sample integrity.

While the ZEN1010 is designed to offer the maximum concentration zeta potential measurement capability with a laser doppler electrophoresis technique, it also offers optimum stability for lower concentration samples. Its minimal sample volume requirements and small capillary are also beneficial for measuring samples with high conductivity.

Compatible with the existing Zetasizer Nano system and accessory range, the reusable high concentration zeta potential cell is easy to use.
