Visão geral

O Zetasizer Ultra é o mais eficiente sistema combinado de DLS e ELS, incorporando as tecnologias de Espalhamento traseiro não invasivo - (NIBS) e, exclusivamente, o Espalhamento de luz dinâmico multi-ângulo (MADLS) para medir os tamanhos de partículas e moléculas. 

A tecnologia NIBS oferece versatilidade e sensibilidade para medir uma grande variedade de concentrações. A tecnologia MADLS, por sua vez, permite visualizar a distribuição de tamanhos em suas amostras em maior resolução para medições mais críticas.

Uma extensão para o MADLS na Etiqueta vermelha do Zetasizer Ultra permite analisar diretamente a concentração de partículas. A medição de concentração de partículas é compatível com diversos materiais, além de exigir pouca ou nenhuma diluição e ser rápida de usar. Por esses motivos, é a técnica de separação ideal. Esse recurso é exclusivo do Zetasizer Ultra. Ele pode ser aplicado inclusive a amostras de vírus e partículas como vírus (VLPs), anteriormente complicadas de serem medidas. 

Diversas células descartáveis e reutilizáveis estão disponíveis para otimizar a medição em termos de volume e concentração da amostra, incluindo o novo kit de células de dimensionamento descartáveis para baixos volumes, que viabiliza a medição de no mínimo 3 µL e extensão a um intervalo de tamanhos maiores nas medições de DLS, graças à supressão das correntes de convecção

Recursos

  • M3-PALS com modo de corrente constante para medições de potencial zeta e mobilidade eletroforética

  • Correlação adaptável para medições de tamanho mais rápidas e replicáveis, com menos preparação de amostra

  • Pacote de software ZS Xplorer para configuração e análise de dados rápidas e flexíveis

  • O Titulador automático MPT-3 opcional permite estudar o efeito das alterações de pH

  • Sistema de qualidade de dados com tecnologia de aprendizado profundo para avaliar quaisquer problemas com qualidade de dados de tamanho e fazer sugestões sobre como melhorar os resultados

  • O novo acessório Sample Assistant reduz o tempo de troca manual de amostras, sem comprometer a qualidade dos dados

  • Filtro óptico com filtro de fluorescência para permitir a medição de amostras fluorescentes sem prejudicar a sensibilidade geral do sistema.  Inclui também filtros de polarização para medições de DDLS

  • A célula de dimensionamento capilar descartável fornece o que há de melhor em análises não destrutivas de baixo volume (mínimo de 3 µL), com um intervalo de tamanho superior que se estende até 10 μm

Key applications

Zetasizer Ultra is ideal for a wide range of applications across many industries, including pharmaceuticals and mining. Find out more below about the key applications for Zetasizer Ultra.

Lipid nanoparticles

Zetasizer Ultra provides rapid, reliable characterization of lipid nanoparticles and viral vectors.

Measure particle size, concentration, polydispersity, and zeta potential to assess stability, yield, and surface charge across formulation development and manufacturing workflows to refine processes and ensure batch-to-batch reproducibility.

Viruses

Speed up analysis of viruses with fast size and concentration measurements. MADLS® technology enables simultaneous size and concentration measurement, determining viral titer and distribution in minutes.

Monitoring these key parameters with Zetasizer Ultra helps you optimize processes, maintain quality, and reduce development time.

Ceramics

The strength of ceramics is linked to particle size, and the Zetasizer Ultra is ideally placed to measure this. Al2O3 samples are often made of differently-sized particles which can easily be identified using MADLS.

In this 0.1% w/v sample, the two particle size populations would not be distinguishable with a single angle DLS measurement.

Resources

Excellent system for characterizing nanoparticles in terms of their Physicochemical properties (size, concentration, polydispersity, and zeta potential). I like the system because it consumes only a few microliters of precious samples to determine and analyze all the properties mentioned above. I highly recommend this system for particle analysis."

One platform, three critical answers

When your work depends on reliable, high-quality data, you need confidence in every measurement. 

Zetasizer Advance Ultra gives you that confidence, combining speed, sensitivity, and flexibility to deliver reproducible results - even when your samples are complex, your users aren’t light scattering experts, or your timelines are tight.

Smarter measurements, faster

Adaptive Correlation automatically adjusts each measurement according to the sample behavior, revealing your sample’s steady state faster, with less time spent re-optimizing methods for changing sample types.

What’s more, our unique machine learning-powered Data Quality Guidance flags results as good, suspect, or poor – and recommends next steps to improve results data quality while eliminating the guesswork.

Deeper insight with multi-angle DLS (MADLS®)

Our patented MADLS® technology provides high-resolution particle size and concentration measurements, revealing fine details single-angle systems can’t. 

MADLS combines multiple detection angles into angle-independent results in minutes, so you’ll quickly see more of what matters - from minor populations to subtle shifts in stability – with data appearing on screen in minutes.  

[Available with Red model only]

Low-volume, high-value precision

Measure from just 1 µL of material with our low-volume sizing cell, ideal for scarce or high-value samples. 

Preserve sample integrity with our patented diffusion-barrier method, protecting sensitive materials from dilution and handling effects.

More results with less hands-on time

Automate the measurement of up to 120 samples from a single setup with Zetasizer Sample Assistant. 

Measurements run unattended while your team focuses on higher-value work – or even overnight. Results are waiting when you return. 

Zetasizer Sample Assistant is an optional accessory that works with all models in the Zetasizer Advance range.

Seamless compliance in regulated environments

For regulated environments, all Zetasizer Advance systems pair with OmniTrust to enable 21 CFR Part 11 compliance, electronic signatures, and complete audit trails.

What our customers say

Zetasizer Ultra Trusted by scientists worldwide to deliver reliable, reproducible data. Don’t just take it from us - here’s what our customers say. 

Excellent system for characterizing nanoparticles in terms of their Physicochemical properties (size, concentration, polydispersity, and zeta potential). I like the system because it consumes only a few microliters of precious samples to determine and analyze all the properties mentioned above. I highly recommend this system for particle analysis.
