Zetasizer Nano Z

Simplify pH, conductivity and additive titrations on your Zetasizer Nano

A cost effective accessory designed to automate the measurement of size and zeta potential as a function of pH, conductivity or any soluble additive.

Viscosity measurement with speed, simplicity and accuracy.

The SV-10 measures viscosity with the accuracy required for dynamic light scattering, for the conversion of diffusion speed to size, and electrophoretic mobility to zeta potential, in an extremely simple and rapid system.

Eliminate sample cross contamination between zeta potential measurements using a completely disposable cell.

The zeta potential of colloids and molecules is extremely sensitive to contamination from components of a previous sample used in a measurement cell. The use of a disposable cell completely eliminates this potential contamination issue.

The folded capillary cell provides the benefits of the accuracy of measurement of a capillary cell with the ease of use of a disposable cell.

Although, disposable, including the electrodes, for low conductivity samples each cell can be used for hundreds of measurements if required.

The cell can be used with the autotitrator, where multiple measurements are routinely done over a wide pH range.

Reusable solvent resistant cell.

Save time and effort by measuring zeta potential with little or no dilution.

The high concentration cell enables the measurement of the zeta potential of samples with little or no dilution in any Zetasizer Advance system that measures zeta potential.

The cell has a flow configuration so can be used for stop-flow size and zeta potential measurements using an MPT-3 autotitrator as well as batch measurements.

Extend the application of the Zetasizer Nano to measure the zeta potential of material surfaces.

The characterization of surfaces and interfaces is critical in a wide range of industries including consumer products, specialty chemicals, pharmaceuticals and life sciences. In each of these application areas, the interaction of molecules and particles with surfaces can influence the material properties of the end product.

The surface zeta potential accessory enables the measurement of the zeta potential of flat surfaces such as filter paper, silica, polymers and bone, using a standard Zetasizer Nano system.

Add flow capability for size measurements to the Zetasizer.

• Measure size and intensity with MPT-2 autotitrator.
• Connect to an SEC system to use as a DLS detector.

Glass cuvette for use with the dip cell.

• For size and zeta potential measurements using the ‘dip’ cell
• Compatible with aqueous and non-aqueous solvents and dispersants

Titrants used by the MPT-2 titrator need regular degassing, ideally before each titration.

Degassing is required to remove bubbles that can affect the volume of titrant dispensed. This is particularly important close to pH 7 where low volumes of titrant are required.

The degasser is a highly recommended ‘Fit and forget’ accessory that continuously degasses titrants which improves the speed of titrations and the accuracy of reaching the target pH. This gives more evenly spaced pH points.
