Litesizer DIF 500 provides sophisticated particle sizing from 10 nm to 3.5 mm, based on nearly 60 years of laser diffraction experience. This laser diffraction particle size analyzer has a best-in-class optical setup, powerful 10 mW and 25 mW lasers, and the market's greatest range of recorded diffraction angles (0.01°-170°).
Litesizer DIF 500
- Measure samples ranging from 0.01 µm to 3,500 µm
- Switch from liquid to dry dispersion in just one move
- Kalliope software: No training is necessary, dedicated QC mode
- Reliable outcomes, even in tough situations
The Kalliope software simplifies particle size analysis and requires no extensive training; measurements begin with three clicks. The Quick-Click method simplifies switching between dispersion units, reducing errors. Safety features for both liquid and dry dispersion provide easy and secure operation.
The sturdy metal enclosure and isolated optical bench assure dependability in every setting, from severe locations to high-tech laboratories.
This is next-generation laser diffraction technology, built on a pioneering tradition- Litesizer DIF 500: From First to Best.
Key Features
On Quality, We Lead the Way

Litesizer DIF’s superior manufacturing makes it the ideal instrument for particle analysis. Its high-quality equipment enables the instrument to gather excellent raw data. With just one analyzer and no additional funding, customers may measure various samples with particle sizes ranging from 0.01 µm to 3500 µm with this laser diffraction particle size analyzer.
Kalliope: The Benchmark Software for Particle Sizing

Due to its one-page workflow, users can get started with Kalliope right away. This workflow includes specifying parameters and obtaining and working with results. The QC mode provides consistent, dependable measurement data by locking sensitive settings and adjusting user management.
The QC mode instrument provides clear feedback if the product falls within the specified bounds. This means that new users need minimal training and only need to make three clicks. Kalliope also complies with the US FDA's 21 CFR Part 11 by offering a pharmaceutical option that includes data security features, user management, and audit trails.
Efficient Dispersion, Maximum Safety

The Litesizer DIF's Quick-Click function links the dispersion units with a single move, eliminating the need for cables, tubes, or pipes. When adding the sample, the obscuration level indication allows users to monitor the sample amount as they add it, ensuring they receive the correct amount from the start.
Dispersion units are developed with safety in mind. The Dry Jet dispersion unit includes a suction check and a built-in dust cover to reduce the possibility of powder distribution. Furthermore, the Liquid Flow dispersion unit automatically checks for enough liquid before sonication, reducing overheating.
Particle Sizing in Any Environment

Anton Paar's Litesizer DIF is ideal for heavy industry. It is built of high-quality materials both inside and out. A sturdy metal housing protects the optical elements. The Litesizer DIF is designed to withstand tough environments: no dust or powder can reach the instrument’s optical bench, and the inside is insulated from direct vibrations at the production site. All of this means lower maintenance and repair costs.
Less Investment, Saved Bench Space – Compatibility Across the Board
