Introducing the NanoFlowSizer FIDES instrument
Instrument for high sensitivity
The NanoFlowSizer THALIA is a NanoFlowSizer system designed for high-sensitivity nanoparticle sizing at low concentrations – ideal for biopharmaceutical and protein-based applications. Using SR-DLS, it provides real-time, non-invasive size and aggregation monitoring (e.g., for proteins and monoclonal antibodies) without dilution or extensive sample preparation.
Based on Spatially Resolved DLS
The THALIA is the sister platform to the NanoFlowSizer FIDES, covering complementary conditions when higher turbidity and in-process monitoring are required.
