Litesizer, DIF 500

Litesizer DIF 500 performs particle size analysis from 10 nm to 3.5 mm via laser diffraction, utilizing dual 10 mW and 25 mW lasers and angular detection from 0.01°–170°. Kalliope software enables three-click measurements. Quick-Click dispersion switching, integrated safety protocols, and a vibration-isolated optical bench ensure precision in demanding environments.

• Measure samples from 0.01 µm to 3500 µm
• Switch between liquid and dry dispersion in just one move
• Kalliope software: No training required, dedicated QC mode
• Reliable results even in harsh environments
