The Litesizer DIA Series, a dynamic image analyzer, allows users to rapidly and consistently assess particle size and form by analyzing their direct images.
Switch seamlessly between three modules (using dispersion liquid, compressed air, or free-fall) for optimal sample dispersion in a single step. Automated features like feed rate adjustment and liquid rinsing make operation easy, enabling accurate measurements with minimal training.
That’s particle analysis at the press of a button, with the power of a dynamic image analyzer.

Key Features
Get Particle Size and Shape in One Measurement

Image Credit: Anton Paar GmbH
Particle sizes between 0.5 µm and 16,000 µm could be precisely measured, and in huge samples, single outlier particles can be found. Make use of a liquid dispersion range of up to 2,500 µm, which leads the market. To learn more about how particle size measurement could enhance the operations, use quick, secure, and dynamic image analysis instead of traditional sieve analysis.
Optimize Measurements with Kalliope Software
Measurements can be taken with just three simple clicks.
The dynamic image analyzer allows users to examine particle size, shape, and images in a single digital space. Kalliope's robust features make it easy to filter particles by specific size and shape. From the Kalliope particle analysis software platform, manage every Anton Paar particle-sizing device.
Prioritize Operator Safety

To safeguard the operator, the Litesizer DIA dynamic image analyzer features several safety measures. Keep oneself safe by using a cover that stops hazardous samples from spreading. Before sonication, use liquid-level detection to prevent overheating. Use automated suction checks to make sure dangerous samples are contained. Adheres to applicable safety regulations, such as ISO 12100:2011 and EN 61010:2010.
Three Dispersion Units in One Dynamic Image Analyzer

Liquid Flow (liquid dispersion), Dry Jet (compressed air), and Free Fall (gravitational fall) dispersion devices are used to measure samples. With the Quick-Click function, users can quickly and simply switch between units, providing unparalleled versatility in a dynamic image analyzer and eliminating the inconvenience of cables and tubes.
Save Time with Automation
Automate filling, draining, and rinsing procedures to free up time for other essential tasks and optimize sample feeding rates.
Improve data quality and expedite analysis by using particle auto-filtering.
