Accessories

NanoSampler

Automated particle size measurement for the Zetasizer Nano

The Zetasizer NanoSampler is a sample delivery system that ensures highly precise and reproducible automated loading of samples into your Zetasizer Nano. The NanoSampler adds automation and unattended operation in a versatile, compact package, maximising the productivity of your Zetasizer Nano. While the benefits of automated operation are useful for all users, the NanoSampler is ideally suited for laboratories where a large number of measurements are required and reproducibility or multi-variate studies are important.

MPT-2

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.

SV-10 viscometer

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.

Cell and cuvette options

Disposable folded capillary cell (DTS1070)

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.

Universal 'dip' cell kit

Reusable solvent resistant cell.

The dip cell is used for the measurement of zeta potential of samples in aqueous and non-aqueous dispersants, and is designed to be cleaned and reused. It is for batch measurements using standard polystyrene or glass cuvettes.

High concentration zeta potential cell kit

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.

Surface zeta potential accessory

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.

Quartz flow cell (ZEN0023)

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.

12mm Glass cell (PCS1115)

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

12mm Square Polystyrene Cuvettes (DTS0012)

Disposable polystyrene cuvettes.

  • 100 disposable cells complete with 100 stoppers to avoid cross-contamination
  • For size measurements using aqueous dispersants
  • Compatible with zeta potential measurements using the dip cell

12mm square glass cell (PCS8501)

Glass cuvette for batch measurements.

  • For size and molecular weight measurements
  • Compatible with aqueous and non-aqueous solvents and dispersants

Disposable Solvent Resistant Micro Cuvette (ZEN0040)

Disposable plastic micro cuvette, for size measurement at 173° (NIBS) optics only.

  • 100 x 40µL cuvettes with 100 caps to avoid cross-contamination
  • Compatible with aqueous samples and a range of other solvents: Acetone, Benzaldehyde, Butanone, Dioxane, DMF, Ethyl acetate, Isopropanol, plus various acids and bases

Low-volume quartz batch cuvette (ZEN2112)

Low-volume quartz batch cuvette for size and molecular weight measurements.

  • Compatible with size and molecular weight measurements with aqueous and non-aqueous solvents and dispersants
  • Minimum sample volume 12 microliters
  • Maximum volume 45 microliters

ZEN0118

Disposable low volume cuvette for size measurement with 90° optics only.

  • 100 x 50µL cuvettes with 100 caps to avoid cross-contamination
  • Compatible with aqueous dispersants

Factory fitted options

Degasser for MPT-2 autotitrator

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.
