Accessory for Litesizer DIA and DIF:
Dispersion Unit
- Dispersion of samples using a carrier liquid
- Automated filling, draining, and rinsing of the dispersion liquid
- Prevention of overheating with automatic recognition of liquid
- Dedicated version with high chemical resistance available for handling aggressive liquids
- Available for the Litesizer DIA and Litesizer DIF series
Measure various samples with four dispersion units: Liquid Flow (wet), Dry Jet (compressed air), Free Fall (gravitational fall), and Liquid Flow Imaging (wet). Switch between dispersion units with the Quick-Click feature in just one move – no need for any extra cables, tubes, or pipes.
Welcome to particle analysis at the touch of a button.
Key features
Absolute operator safety
- Safety cover prevents toxic or explosive sample spread
- Liquid level recognition before sonication prevents overheating
- All toxic or explosive samples contained

Automated dispersion units
- Automated filling, draining, and rinsing of dispersion liquid
- Optimal sample feeding rate set automatically
- Filtering and identification of all particles of interest
- Optimized results data size

Four powerful dispersion units
- Liquid Flow (wet): Carrier liquid for dispersion; a dedicated version with high chemical resistance is also available for handling aggressive liquids
- Dry Jet (compressed air): Perfect for dispersing dry agglomerates
- Free Fall (gravitational fall): Dry and free-flowing materials (Litesizer DIA series)
- Liquid Flow Imaging (wet): Combination of laser diffraction with dynamic image analysis
