Anton Paar – Litesizer 500 – Partikkelanalysator, nano/mikro
Modell: Litesizer 500
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.
With cmPALS (European Patent 2 735 870), measurements can be performed at much lower applied electric fields, and within significantly shorter measuring times, thereby enabling reliable measurements of even highly sensitive samples.
Unique Ω-shaped capillary tube for zeta potential
Measurements are more stable and reproducible because of the unique Ω-shaped capillary in the cuvette.
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.
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).
Ingeniously simple software, Kalliope™
Kalliope™ provides an intuitive one-page workflow, where input parameters, measurements and analyses are all at hand. Kalliope™ is fully compliant with the FDA’s 21 CFR part 11 FDA regulations.
