Aurora is a microfluidic modulation spectroscopy (MMS) benchtop instrument for studying and testing structural characterizations for biomolecules. This technology is used in the drug development process under biological and pharmacological conditions to yield more information about proteins, antibodies, peptides, and other biomolecules. Aurora allows industry and academic labs to work with smaller sample volumes, enabling them to push the boundaries of structural characterizations for biomolecules. It is an automated system that saves time, labor, and lab space by incorporating all the benefits of a much larger set of equipment and processes into a smaller footprint with an improved user experience.
