Dynamic Image Analyzer: Litesizer DIA
With Litesizer DIA Series, our dynamic image analyzer, you can easily and reliably characterize the size and shape of particles via analysis of their direct images.

Manufacturer: Anton Paar — Austria
Overview
With Litesizer DIA Series, our dynamic image analyzer, you can easily and reliably characterize the size and shape of particles via analysis of their direct images. In just one step, quickly switch among three modules that use dispersion liquid, compressed air or free-fall for excellent dispersion of your sample. Rely on the automation of feeding rate adjustment and rinsing of liquids, and conduct measurements with only minimal training. That's particle analysis at the touch of a button - only with our dynamic image analyzer.
Get Particle Size and Shape in One Measurement
Measure particle sizes ranging from 0.5 µm to 16,000 µm with precision, and detect single outlier particles in large samples. Utilize a market-leading liquid dispersion range of up to 2,500 µm. Replace traditional sieve analysis with fast, safe, and dynamic image analysis to gain a deeper understanding of how particle size measurement can optimize your processes.
Optimize Measurements with Kalliope Software
Start your measurements in just three clicks. Analyze particle size, shape, and images all in one digital space with our dynamic image analyzer. Easily filter particles by specific size and shape using Kalliope's powerful features. Control all your Anton Paar particle-sizing instruments from the Kalliope particle analysis software platform.
Prioritize Operator Safety
The Litesizer DIA dynamic image analyzer incorporates multiple safety features to protect the operator. Stay safe with a cover that prevents dangerous sample spread. Prevent overheating with liquid level recognition before sonication. Ensure containment of hazardous samples with automatic suction checks. Comply with relevant safety standards, including EN 61010:2010 and ISO 12100:2011.
Efficient Dispersion, Maximum Safety
The Litesizer Quick-Click feature connects the dispersion units in just one move – no hassle with cables, tubes, or pipes. The Dry Jet dispersion unit features a suction check and built-in dust cover to minimize the risk of powder spread. The Free Fall dispersion unit provides gentle, low-energy sample dispersion for coarse and sensitive materials. By minimizing mechanical stress, it helps preserve particle shape and integrity, making it ideal for granules, crystals, fibers, sands, and weakly agglomerated particles. The Liquid Flow unit automatically checks for sufficient liquid before sonication, preventing overheating. A dedicated module with high chemical resistance is available for aggressive liquids. The Small Flow unit is designed for applications with limited, expensive, toxic, or corrosive solvents, and reduces liquid consumption while expanding measurement flexibility.
Save Time with Automation
Automatically optimize sample feeding rates, and automate filling, draining, and rinsing tasks to focus on more important work. Enhance data quality and speed up analysis with auto-filtering of particles.
