| Description | Couple the miniDAWN™ to your favorite HPLC or FPLC to determine the absolute molar masses and sizes of macromolecules and nanoparticles in solution from hundreds to millions of Daltons—without the need for column calibration standards. This sensitive unit requires as little as 25 ng injected Couple the miniDAWN™ to your favorite HPLC or FPLC to determine the absolute molar masses and sizes of macromolecules and nanoparticles in solution from hundreds to millions of Daltons—without the need for column calibration standards. This sensitive unit requires as little as 25 ng injected sample, 100 kDa polystyrene in THF (varies for other samples and solvents). The miniDAWN is engineered with self-contained modules that are easily replaced making it field serviceable. The system-ready monitors soise levels in real-time and an all-green status indicator lets you know when your system is ready for data collection. The optional DLS module uses the WyattQELS™ module, which fits inside the miniDAWN to providing on-line dynamic light scattering for determining radii down to 0.5 nm. All light scattering cells are subject to contamination by particles and to combat this issue the instrument has a self-cleaning, embedded COMET™ ultrasonic module. For maximum reliability and uptime, program the miniDAWN to automatically clean the cell after every run. The units may also be combined with a Calypso™ composition-gradient system to characterize biomolecular interactions....

Speed up protein formulation development and screening Accelerate protein formulation development and screening for therapeutic drug development
Protein stability analysis and preventing aggregation are is crucial when developing therapies. That’s why it’s time to leave flow cell imaging behind.
Speed up protein formulation development and screening with Aura PTx. With just 5 µL of a sample, discover a faster way to detect, count and characterize excipients and drug products at earlier stages of therapeutic development.
Now you can quickly identify and count aggregates that form due to degraded polysorbate in your formulation. And with two-channel fluorescence, determine if aggregation in your protein therapy is caused by proteins or polysorbates in your sample – at the same time.
Features:- Learn more with innovative technology. Aura PTx System combines backgrounded membrane imaging (BMI) with two channels of fluorescence membrane microscopy (FMM) to give you protein aggregate data without the need to clean between measurements.
-
ID protein aggregates. Accurately detect excipient degradation within your formulations and distinguish between protein and non-protein particles effortlessly.
-
Monitor polysorbate degradation. With fluorescence applications, you can track polysorbate degradation to confidently evaluate the stability of your product.
-
Analyze small volumes. You only need 5 µL of sample, allowing you to start characterizing protein aggregates earlier in development.

Read More | Unique among its peers, the DynaPro™ Zetastar™ performs simultaneous dynamic and static light scattering or dynamic and electrophoretic light scattering (DLS/SLS/ELS) measurements all within one instrument. Automate measurements of zeta potential and size for up to 96 samples at a time Unique among its peers, the DynaPro™ Zetastar™ performs simultaneous dynamic and static light scattering or dynamic and electrophoretic light scattering (DLS/SLS/ELS) measurements all within one instrument. Automate measurements of zeta potential and size for up to 96 samples at a time or measure manually with cuvettes with the walk-up touch screen functionality for optimal efficiency. Quickly quantify size, polydispersity, zeta potential/charge, particle concentration, molar mass or turbidity for characterization and stability studies.
Key Features:
- DYNAMICS™ Touch on-board app for walk-up, self-guided operation
- Pairable with a Waters HPLC and Pump to automate measurements of zeta potential and size
- Flow Mode for best-in-class zeta potential reproducibility and precision for samples in high salt buffers or prone to degradation
- Adaptive collection for faster and simpler measurements of zeta potential
- Measure size and turbidity with just 2 µL of solution, or zeta potential with as little as 65 µL of solution
- A selection of high-quality quartz and disposable cells and cuvettes for both size and zeta potential measurements
