The Litesizer DIF series delivers precise particle sizing across a wide range from 10 nm to 3.5 mm, backed by nearly six decades of laser diffraction expertise. Featuring a best-in-class optical setup, it combines powerful 10 mW and 25 mW lasers with the industry’s broadest detected diffraction angle range, spanning 0.01° to 170°.
Designed for ease of use, the Kalliope software streamlines the measurement process - getting started takes just three clicks, with no extensive training required. The intuitive Quick-Click system enables fast, tool-free switching between dispersion units, reducing the risk of setup errors. Built-in safety features for both wet and dry dispersion ensure smooth, secure operation.
With a durable metal housing and an isolated optical bench, the Litesizer DIF performs reliably across a wide range of environments, from rugged industrial settings to advanced research labs.
Building on a legacy of innovation, the Litesizer DIF series represents the next step in laser diffraction technology - precision, made effortless.

Key Features
Particle Sizing in any Environment
The Litesizer DIF is designed to withstand the demands of heavy industrial environments, thanks to its high-quality components and sturdy metal housing.
Its robust construction ensures that no dust or powder can penetrate the optical bench, and the interior is isolated from direct vibrations at the production site. This exceptional durability translates into significant savings on upkeep and repair costs.

Kalliope: The Benchmark Software for Particle Sizing
The Kalliope software is designed for immediate and intuitive use, featuring a one-page workflow that simplifies parameter setting, data acquisition, and results analysis. This streamlined process allows users to get results in just three clicks, significantly reducing training time.
For consistent, reliable results, the QC mode offers customizable user management and allows for the locking of delicate settings. In this mode, the instrument provides simple feedback on whether your product is within its defined limits.
A pharma option is available that includes robust data security functions, user management, and audit trails, making the software compliant with the US FDA’s 21 CFR Part 11 regulations.

Efficient Dispersion, Maximum Safety
The Litesizer DIF’s Quick-Click feature connects dispersion units in a single, seamless step - there is no need for extra cables, tubes, or pipes. An integrated obscuration level indicator lets users monitor the sample amount in real time, ensuring accurate dosing from the very beginning.
For dry samples, the Dry Jet dispersion unit includes a suction check and a built-in dust cover to help prevent powder from spreading.
The Liquid Flow unit automatically verifies that there is enough liquid before starting sonication, reducing the risk of overheating. A high-resistance module is available to handle chemically demanding samples in particularly aggressive media.
Additionally, the Liquid Flow Imaging unit combines laser diffraction with dynamic image analysis, enabling users to capture particle shape parameters starting from 5 µm in size.
