Malvern Zetasizer Ultra
Dynamic Light Scattering (DLS) Particle Size and Zeta Potential Analyser
The Malvern Zetasizer Ultra is a combined particle size (DLS) and zeta potential analyser (ELS) with the facility to also measure particle concentration. It can be used in a wide range of applications; emulsion and formulation stability, biotechnology, shelf life studies, pharmaceuticals.
Malvern Zetasizer DLS
- Capable of measuring particle sizes from below 1 nm to 10 µm.
- Can also measure the zeta potential of particles and molecules, indicating sample stability and/or propensity to aggregate.
- Multi-Angle Dynamic Light Scattering (MADLS) scheme for absolute confidence in particle and molecular size distribution analysis
- Non-Invasive Back-Scatter (NIBS) optics for versatile, high sensitivity, particle and molecular size measurements
- Optical filter wheel with fluorescence filter to allow measurement of fluorescent samples without impairing overall system sensitivity. Also includes polarization filters for DDLS measurements
- Capillary cell for low volume measurements (down to 3uL)

Malvern Mastersizer 3000
Laser Diffraction Particle Size Analyser
The Mastersizer 3000 is a laser diffraction particle size analyzer that can measure particle size distributions for both wet and dry dispersions. It is capable of measuring particles from the nanometer to millimeter size ranges. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern.
Malvern Mastersizer 3000
The system has two sample dispersion units:
- The Hydro EV is a flexible volume wet dispersion unit that can be used with standard laboratory glassware. It is suitable for a wide variety of dispersant volumes and particle size ranges.
- The Aero S is a state-of-the-art dry powder dispersion unit. It is modular in design, meaning that it is easily configured for different applications.
