In a method and system for forming concentrated volumes of microbeads, a polymer solution and/or suspension includes a polymer dissolved and/or dispersed in a medium. Streams of a focusing fluid and of the polymer solution and/or suspension flow towards a fluid bath, and into intersection with one another, so &s to focus the polymer solution and/or suspension. The polymer solution and/or suspension stream forms microbeads in the fluid bath. Some of the focusing fluid is drawn from the fluid bath, so as to concentrate the microbeads in die fluid bath. The system includes a flow focusing apparatus and a liquid-containing cell. The focusing apparatus includes polymer and focusing nozzles. The cell contains the fluid bath and has an outlet port, through which the focusing fluid is drawn from the fluid bath.
Dans un procédé et un système pour former des volumes concentrés de microbilles, une solution et/ou suspension de polymère comprend un polymère dissous et/ou dispersé dans un milieu. Des courants d'un fluide de focalisation et de la solution et/ou suspension de polymère coulent vers un bain de fluide, et en intersection l'un avec l'autre de façon à focaliser la solution et/ou suspension de polymère. Le courant de solution et/ou suspension de polymère forme des microbilles dans le bain de fluide. Une partie du fluide de focalisation est éliminée du bain de fluide de façon à concentrer les microbilles dans le bain de fluide de filière. Le système comprend un appareil de focalisation du courant et une cellule contenant un liquide. L'appareil de focalisation comprend un polymère et des buses de focalisation. La cellule contient le bain de fluide et possède un orifice de sortie par lequel le fluide de focalisation est éliminé du bain de fluide.
