Zeta Potential Measurement Cell handles concentrated samples.
October 2, 2009 -
Designed for Zetasizer Nano particle characterization system, ZEN1010 enables measurement in samples up to 40% w/v. Design incorporates minimized optical path length and takes just 150 µl sample in measurement area. Although it operates as standard cell, ZEN1010 allows zeta potential measurements in highly concentrated samples. By requiring less sample dilution, it supports optimized maintenance of pH and chemical structure of sample for directly relevant zeta potential measurement.

Introducing the New ZEN1010 - for High Concentration, Low Volume Zeta Potential Measurement on the Zetasizer Nano
Malvern, UK: The new ZEN1010 high concentration zeta potential cell for the market leading Zetasizer Nano particle characterization system from Malvern Instruments 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. Suitable for measurement in aqueous media, the new cell takes just 150 µl 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.

About Malvern Instruments
Malvern Instruments provides a range of complementary materials characterization tools that deliver inter-related measurements reflecting the complexities of particulates and disperse systems, nanomaterials and macromolecules. Analytical instruments from Malvern are used in the characterization of a wide variety of materials, from industrial bulk powders to nanomaterials and delicate macromolecules. A broad portfolio of innovative technologies is combined with intelligent, user-friendly software. These systems deliver industrially relevant data enabling our customers to make the connection between micro (such as particle size) and macro (bulk) material properties (rheology) and chemical composition (chemical imaging).
Particle size, particle shape, zeta potential, molecular weight, chemical composition and rheological properties measurements are now joined by advanced chromatography solutions (GPC/SEC), extending Malvern's technologies for protein molecular weight, size and aggregation measurements, and synthetic polymer molecular weight and distribution. The company's laboratory, at-line, on-line and in-line solutions are proven in sectors as diverse as cement production and pharmaceutical drug discovery.
Headquartered in Malvern, UK, Malvern Instruments has subsidiary organizations in all major European markets, North America, China, Korea and Japan, a joint venture in India, a global distributor network and applications laboratories around the world.
