Dynamic Light Scattering Instrument, Litesizer DLS 101

Litesizer DLS enables high-resolution particle sizing via MAPS multi-angle dynamic light scattering and automatic angle optimization. Continuous transmittance monitoring detects sedimentation and agglomeration in real time. cmPALS and Omega Cuvette enhance zeta potential precision by mitigating aging and field distortion. Fluorescence/polarization filters support concentration analysis across MAPS modes.

• Particle sizing from 0.3 nm to 10 µm
• Cost-effective entry to dynamic light scattering
• DLS back-scatter detection ensures broad sample coverage
• Transmittance measurement to live-monitor sample behavior
