Litesizer DIF offers advanced particle sizing from 10 nm to 3.5 mm, drawing on nearly 60 years of laser diffraction expertise. This laser diffraction particle size analyzer boasts a best-in-class optical setup, which yields superior results. An optional image analysis module is available for additional shape analysis and reliable detection of oversized particles.
The Kalliope software simplifies particle sizing, requiring no extensive training – measurements start with just three clicks. The Quick-Click system allows easy switching between dispersion units, minimizing errors. Safety features for both liquid and dry dispersion ensure effortless, secure operation.
The robust metal housing and the isolated optical bench ensure reliability everywhere: from harsh environments, to high tech laboratories.
Fueled by our pioneering legacy, this is next-generation laser diffraction technology – Litesizer DIF: From First to Best.
Key features
On quality, we lead the way
Litesizer DIF is the perfect tool for particle analysis due to its high-quality manufacturing. It features high-grade hardware, empowering the instrument to collect superior raw data. Litesizer DIF 500 enables users to measure a broad range of samples, covering particle sizes from 0.01 µm to 3,500 µm. Litesizer DIF 300 and 100cover a more targeted range for dedicated analysis of narrower size distributions.
Kalliope: The benchmark software for particle sizing
With Kalliope, users immediately know how to get started, via the one-page-only workflow (setting parameters, acquiring and working with results). Additionally, QC mode offers consistent reliable measurement results by customizing user management and locking delicate settings. The instrument in QC mode gives simple feedback if your product is within your defined limits. This means results in just three clicks and less training for new users. In addition, a pharma option with data security functions, user management, and audit trails is included, making Kalliope compliant with the US FDA’s 21 CFR Part 11.
Efficient dispersion, maximum safety
Litesizer DIF's Quick-Click feature connects the dispersion units in just one move – no hassle with cables, tubes, or pipes. When it comes to adding the sample, the obscuration level indicator allows you to monitor the sample amount while adding it, ensuring you get the right amount from the start. Our dispersion units are designed with safety in mind: The Dry Jet dispersion unit has a suction check and built-in dust cover to minimize the risk of powder spread. Plus, the Liquid Flow dispersion unit automatically checks for sufficient liquid before sonication, preventing overheating.
Particle sizing in any environment
Anton Paar's Litesizer DIF is suitable for heavy industries. It is made of high-quality components inside and out, and has a 10-year warranty on the lasers. Sturdy metal housing encases durable optical elements. Litesizer DIF is built to endure harsh environments: No dust or powder can penetrate into the optical bench of the instrument, and the inside of the instrument is isolated from possible direct vibrations at the production site. All of this means you save on upkeep and repair costs.
Sharper Results with Image-Enhanced Diffraction
Litesizer DIF can be enhanced by image analysis, which gives an additional insight into the particle shape and allows detection of single oversized particles.
Compatibility of dispersion units between Anton Paar’s Litesizer DIA and Litesizer DIF instruments reduces investment costs and lab space usage. On top of that, all Litesizer instruments can be operated using a single PC with the Kalliope software installed.
