Abstract
An apparatus for making solid beads is provided, the apparatus comprising at least one liquid droplet generator operable to generate droplets comprising a solute dissolved in a solvent, and at least one flow channel for carrying a second liquid, at least one liquid droplet generator and at least one flow channel being spaced relative to one another so that, in use, liquid droplets pass through a gas into a second liquid provided in said flow channel, the solvent being soluble in the second liquid so as to cause the solvent to exit the droplets, thus forming solid beads. A method of preparing solid beads is also provided.
