Litesizer™ 100

Particle analysis at the touch of a button

The Litesizer™ 100 is an instrument for characterizing nano- and microparticles in dispersions and solutions. It determines particle size by measuring dynamic light scattering (DLS).

A highlight of the Litesizer™ 100 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.

Key Features

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. In addition, Kalliope™ is fully compliant with the US FDA's 21 CFR part 11 regulations.
