Dynamic Light Scattering Instruments
DynaPro™ Plate Reader III
High-throughput, automated dynamic light scattering.
The DynaPro Plate Reader III provides unparalleled levels of productivity and flexibility for the most demanding nanoparticle sizing and protein aggregation tasks such as biotherapeutic formulation, screening of promiscuous inhibitors, and optimization of protein crystallization conditions. Measurements are performed in situ with no fluid transfer. Select from industry-standard 96-, 384- or 1536-microwell plates.
DynaPro™ NanoStar™ II
Traditional dynamic light scattering, just better.
The DynaPro NanoStar operates in traditional microcuvette-based format to analyze size distributions and particle concentrations of proteins, nanomedicines, viruses, vesicles, emulsions, micelles and metallic nanoparticles. It uniquely combines two optimized 90° detections channels: one for DLS and one for static light scattering. Providing walk-up operation via an intuitive touch-screen app, the NanoStar performs robust, accurate measurements with as little as 2 µL of sample.
DynaPro™ ZetaStar™
Walk-up or automated measurements of dynamic, static and electrophoretic light scattering.
The ZetaStar operates with an autosampler, or manually using microcuvettes, to measure a sample’s size distribution, particle concentration, molecular weight, turbidity, and zeta potential. Proteins, nanomedicines, viral vectors, extracellular vesicles, nano emulsions, and polymers can all be analyzed in a variety of solvents, including salt concentrations greater than physiological conditions.
