The DynaPro Plate Reader 3 is a commercially available microplate that is a light scattering measurement device capable of measuring the size, molecular weight, concentration, and interactions of proteins, nanoparticles, and other polymers. This plate-based device allows for very high-throughput measurements compared to traditional cuvette-based light scattering devices. Additionally, after dispensing into the plate, there is no need to touch the liquid, minimizing sample carryover. 【Features】 - Compatible with commercially available microplates - Supports high-throughput measurement of multiple samples and automation - Simultaneous measurement of dynamic light scattering (DLS) and static light scattering (SLS) - Saves time and running costs - Non-destructive measurement allows the measured plates to be repurposed for other analytical devices

The DynaPro NanoStar 2 supports both dynamic light scattering (DLS) and static light scattering (SLS) measurements, allowing for the measurement of particle size distribution, particle concentration, interactions (kD, A2), and weight average molecular weight (Mw) of nanoparticles and proteins. It can be used for the analysis of proteins, gene therapy vectors, viruses and virus-like particles, indiscriminate inhibitors, micelles, liposomes, LNPs (lipid nanoparticles), and metal nanoparticles. To accommodate rare and precious samples, the specially designed quartz cuvette provides robust and accurate measurements with just 2 µL of solution. 【Features】 - Supports both dynamic light scattering (DLS) and static light scattering (SLS) measurements - Easy operation with an intuitive touchscreen - Achieves a wide range of temperature settings (-10 to 120°C) and fast temperature gradient settings - Connects with the multi-angle light scattering detector DAWN to support flow DLS measurements - Abundant cell options (2μL capacity quartz cell, 4μL capacity disposable cell, commercially available 4mL quartz cell, disposable cell (using adapter))

The DynaPro ZetaStar can measure dynamic light scattering, static light scattering, and electrophoretic light scattering (DLS/SLS/ELS) all in one device, allowing for the acquisition of information on a wide range of molecular sizes, polydispersity, zeta potential, particle concentration, molecular weight, and turbidity/milky degree in up to 1/10 the time compared to conventional methods. It can be used for the analysis and quantification of virus vectors, vesicles, LNPs (lipid nanoparticles), inorganic nanoparticles, nanoemulsions, polymers, peptides, proteins, nucleic acids, and more. With high sensitivity even with very small sample amounts, it is suitable for rare and precious samples. 【Features】 - Supports both manual and automatic measurements - Measurement is completed with just a few clicks, making it easy to operate and reassuring for inexperienced users - Wide temperature setting range (-10 to 120°C) allows for evaluation of thermal degradation and behavior under various storage conditions - High salt concentration compatibility enables reliable measurements under physiological conditions and in formulation buffers - A variety of cell options and disposable cell compatibility eliminate the need for cuvette cleaning and sample carryover
