The Litesizer DIA 500 from Anton Paar GmbH is a dynamic image analyzer that leverages the power of direct image acquisition to deliver straightforward, reliable characterization of particles’ size and shape.
Users can switch between the instrument’s three modules in a single step, ensuring excellent sample dispersion whether using dispersion liquid, compressed air, or free-fall methods.
Particle analysis and measurements can be completed at the touch of a button, with minimal training requirements, thanks to a range of automated features, including feeding rate adjustment and liquid rinsing.
Key Features
A Single Measurement for Particle Size and Shape

The Litesizer DIA 500 delivers several advantages over conventional sieve analysis. These include:
- The capacity to measure samples’ size and shape with a broad particle size range of 0.8 µm to 8000 µm
- The ability to detect and analyze even single outlier particles in populations counted in millions
- A market-leading liquid dispersion range of up to 2500 µm
- Improved insight into particle size and shapes’ impact on processes
Optimized Measurements via the Kalliope Software

The measurement process can be streamlined and optimized using the Kalliope software:
- The measurement process can be started in just three clicks.
- Kalliope's one-page workflow allows size, shape, and image analysis in one digital space.
- Kalliope’s powerful filtering features enable the location of particles with a specific size and shape in just a few clicks.
- All Anton Paar particle-sizing instruments can be controlled within Kalliope.
Ensuring Operator Safety

The Litesizer DIA 500 places operator safety at the core of its functionality. Safety features include:
- An integrated safety cover prevents dangerous sample spread.
- Sonication will not commence until there is enough liquid in the system, meaning that the dynamic image analyzer will never overheat.
- An automated suction check ensures that any dangerous samples are contained.
- Robust protection against ingress of water and particles.
Full compliance with relevant safety standards including EN 61010:2010 and ISO 12100:2011.
Three Dispersion Units in One Dynamic Image Analyzer

The Litesizer DIA 500 features three dispersion units, enabling the measurement of various samples:
- Liquid Flow (dispersion liquid)
- Dry Jet (compressed air)
- Free Fall (gravitational fall)
The Quick-Click feature allows users to switch between dispersion units in one move, without the need to adjust or change tubes, pipes, or cables.
Powerful Automated Features

The Litesizer DIA 500’s range of automation features enables streamlined, efficient measurement and analysis while allowing users to focus on other critical tasks. These include:
- Automatic setting of the optimal sample feeding rate
- Automated filing, draining, and rinsing of the dispersion liquid
- Optimized data inflow features maximize data quality and expedite analysis, including the auto-filtering of particles of interest.
