Abstract

In this paper, we present a crystallization platform that couples capillary microflsuidics-based emulsion generation with evaporative crystallization for the production of monodisperse spherical agglomerates of glycine, a model molecule for API crystallization studies. This platform enables us to produce exquisitely uniform spherical agglomerates (SAs) in industrially relevant size ranges. Furthermore, on-line high-speed imaging provides valuable and hitherto unmatched insights into crystallization dynamics within emulsion droplets. We show that our system can be extended to other analogous molecules in a straightforward fashion. We also discuss several crucial aspects of crystallization dynamics that could extend our system's applicability to industrially relevant solutes.
