Key Features
Get Particle Size and Shape in One Measurement

Image Credit: Anton Paar GmbH
Accurately measure particle sizes from 0.5 µm to 16,000 µm and identify single outlier particles in big samples. Use the market-leading liquid dispersion range of up to 2,500 µm. Replace traditional sieve analysis with quick, safe, and dynamic image analysis to better understand how particle size measurement can help users enhance their operations.
Optimize Measurements with Kalliope Software

Image Credit: Anton Paar GmbH
Start the measurements with simply three clicks. With the dynamic image analyzer, users can analyze particle size, shape, and images in the same digital environment. Kalliope’s strong capabilities allow users to easily filter particles based on their size and form. The Kalliope particle analysis software platform allows one to control all of the Anton Paar particle size devices.
Prioritize Operator Safety

The Litesizer DIA dynamic image analyzer features several safety measures to protect the operator. Stay safe with a cover that stops harmful samples from spreading. Prevent overheating by detecting liquid levels before sonication. Automatic suction inspections ensure the safe containment of dangerous materials. Comply with all applicable safety requirements, including EN 61010:2010 and ISO 12100:2011.
Three Dispersion Units in One Dynamic Image Analyzer
Samples are measured using Liquid Flow (liquid dispersion), Dry Jet (compressed air), and Free Fall (gravitational fall) dispersion devices. Experience unparalleled versatility in a dynamic image analyzer with the Quick-Click function, which allows users to switch between units fast and effortlessly without the burden of cables and tubes.
Save Time with Automation
