Zetasizer Ultra

The new Zetasizer Ultra is our most advanced system for the measurement of particle and molecular size, particle charge and particle concentration, and represents the most intelligent and flexible instrument in the Zetasizer Advance range. 

Our flagship model enjoys all the benefits afforded by ZS Xplorer software, in terms of ease of use, analysis speed and data confidence, and also offers two unique measurement capabilities: Multi-Angle Dynamic Light Scattering (MADLS) and particle concentration*, to offer even greater insight into your samples.

ZS Xplorer version 3.3 extends OmniTrust support to the Studies features of the main application. Previously OmniTrust users were prevented from accessing Studies to prevent un-audited events. From 3.3 OmniTrust users can now access Studies for Molecular Weight and associated parameters with permissions and auditing of events within the Studies features.  


Note that Studies by their nature are intended for advanced users and to be flexible in their analysis. Users not requiring Studies features can still prevent access to these features using permissions in OmniAccess.


Version 3.3 also addresses a few minor bug fixes.


See SUN for full details.

Accessories

Configure the Zetasizer Ultra for your applications and requirements with our range of configuration options:

Zetasizer Ultra accessories

Zetasizer sample assistant

Empowering scientists, one automated test at a time

Significantly improve your system utilization with the Sample Assistant – a new accessory for every Zetasizer Advance system. It frees the operator from manually changing samples. 

The result? The same great data quality and versatility you expect from your Zetasizer Advance with even greater efficiency.

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.

MPT-3 Autotitrator

Automate your pH titrations

The MPT-3 is a cost-effective accessory for the Zetasizer Advance range, designed to automate your Zeta and/or Size vs. pH titrations, helping you understand how your materials behave as a function of pH.    

The zeta potential and/or size of your materials with pH changes can be critical in understanding: 

  • Material stability
  • Agglomeration
  • Flocculation 
  • Point of net-zero charge (isoelectric point)
  • Storage conditions

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.

Low-volume disposable sizing cell kit (ZSU1002)

Our low volume disposable sizing cell (ZSU1002) design is unique in offering easy-fill, ultra-low volume size measurement in as little as 3 μL. 

  • Measure larger particles (up to 10 μm) with greater accuracy thanks to the inherent physical qualities of the capillary sizing cell
  • The cell also eliminates the errors associated with multiple scattering, allowing samples to be measured over a wider dynamic concentration range than would normally be possible at side scatter (90°)
  • The use of ZSU1002 is supported on Zetasizer Lab and Zetasizer Ultra models
12mm square glass cell (PCS8501)

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
12mm Glass cell (PCS1115)

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
Low-volume quartz batch cuvette (ZEN2112)

Low-volume quartz batch cuvette (ZEN2112)

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

This quartz cuvette holds between 12 μL and 45 μL of sample and is used for size measurements. It is compatible with both aqueous and non-aqueous solvents and dispersants.

12mm Square Polystyrene Cuvettes (DTS0012)

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
Disposable Solvent Resistant Micro Cuvette (ZEN0040)

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
