Particle analysis at the touch of a button
The Litesizer™ 500 is an instrument for characterizing nano- and microparticles in dispersions and solutions. It determines particle size, zeta potential, and molecular mass by measuring dynamic light scattering (DLS), electrophoretic light scattering (ELS), and static light scattering (SLS).
A highlight of the Litesizer™ 500 is its ingeniously simple software. We have created a one-page workflow, where input parameters, results and analysis are all on a single page: You can set up your experiments in a few seconds, and produce the analyses and reports you need at the touch of a button.
Continuous transmittance measured automatically
Transmittance gives you instant feedback about your sample, and allows automatic optimization of measurement parameters (angle, focus position, and measurement duration).
Accurate determination of the refractive index
While for most particle analyzers these indices must be determined from external sources, the Litesizer™ 500 is able to measure the refractive index for the exact wavelength and temperature of your experiment. This ensures maximum accuracy of particle size and zeta potential results under all experimental conditions.
The Litesizer™ 500 determines the solvent refractive index within ±0.5 %, as defined by ISO 22412:2017 concerning the accuracy of the refractive index required for DLS.
Particle-size measurements: Unprecedented resolution
Several different particle sizes in a single suspension can be precisely resolved, thanks to highly developed algorithms in the firmware.
